How to settle it if there is water existed inside the compressor of temperature humidity chamber?

May 08, 2019 | Climatest Symor

It is necessary to know there are some faults that cannot be entirely avoided during the use of temperature and humidity test chamber, but how to deal with them in time is a problem that needs to be paid attention to.Here mainly explain the temperature and humidity test chamber compressor in the reason for the water, and how to deal with it. Reason: water comes from air, because there is always water in the air, known as humidity, which is compressed into supersaturated air and then analyzed to become liquid. The oil comes from the lubrication system of the compressor, possibly because the wear clearance of the mechanism increases, and the lubricating oil will escape into the cylinder. Solution: after the compressor is removed from the temperature and humidity test chamber, with a larger gas storage tank, the oil and water will naturally settle down to the bottom of the jar, and we need to discharge regularly to reduce the oil and water content in the compressed air. Of course, you can also use filters and other things to further reduce the content of oil and water. if you need to know more details about climatic chamber, keep an eye on our website www.climatechambers.com...

Notices in the use of temperature and humidity Test Chamber

May 06, 2019 | Climatest Symor

The temperature and humidity test chamber simulate the temperature and humidity, so there are a lot of things customers shoud notice in the process of use, although there is detailed instruction when purchasing the equipment. But some users just know how the device works and start using it. This is very easy to cause problems in the use of the equipment, so Symor intends to describe the safety details during the use of temperature and humidity chamber. 1. Before the test, determine if the sample contains flammable and explosive substances to avoid combustion or explosion during the test. Of course, also make sure there is no flammable and explosive material around the test equipment, otherwise it may cause fire and other accidents. 2, Do not open the chamber door to operate during the experiment, or the gas in the studio may cause the operator to burn and so on. 3. At the end of the test or at the time of regular cleaning of the test chamber, power off the equipment to avoid electrocution accidents. Also, when cutting off the equipment power, pull the power cord to pull out the plug, otherwise it may lead to a rupture of the power cord and so on. You can contact manufacturers if there are some places you donnot understand, do not dismantle and repair the temperature and humidity test chamber without authorization, otherwise it may lead to more serious problems....

A New Line Balancing Method Considering Robot Count and Operational Costs in Electronics Assembly

May 02, 2019 | Ryo Murakami, Sachio Kobayashi, Hiroki Kobayashi, Junji Tomita

Automating electronics assembly is complex because many devices are not manufactured on a scale that justifies the cost of setting up robotic systems, which need frequent readjustments as models change. Moreover, robots are only appropriate for a limited part of assembly because small, intricate devices are particularly difficult for them to assemble. Therefore, assembly line designers must minimize operational and readjustment costs by determining the optimal assignment of tasks and resources for workstations. Several research studies address task assignment issues, most of them dealing with robot costs as fixed amount, ignoring operational costs. In real factories, the cost of human resources is constant, whereas robot costs increase with uptime. Thus, human workload must be as large and robot workload as small as possible for the given number of humans and robots. We propose a new task assignment method that establishes a workload balancing that meet precedence and further constraints....

Controlling Moisture in Printed Circuit Boards

May 01, 2019 | Bhanu Sood, Michael Pecht

Moisture can accelerate various failure mechanisms in printed circuit board assemblies. Moisture can be initially present in the epoxy glass prepreg, absorbed during the wet processes in printed circuit board manufacturing, or diffuse into the printed circuit board during storage. Moisture can reside in the resin, resin/glass interfaces, and micro-cracks or voids due to defects. Higher reflow temperatures associated with lead-free processing increase the vapor pressure, which can lead to higher amounts of moisture uptake compared to eutectic tin-lead reflow processes. In addition to cohesive or adhesive failures within the printed circuit board that lead to cracking and delamination, moisture can also lead to the creation of low impedance paths due to metal migration, interfacial degradation resulting in conductive filament formation, and changes in dimensional stability. Studies have shown that moisture can also reduce the glass-transition temperature and increase the dielectric constant, leading to a reduction in circuit switching speeds and an increase in propagation delay times.

This paper provides an overview of printed circuit board fabrication, followed by a brief discussion of moisture diffusion processes, governing models, and dependent variables. We then present guidelines for printed circuit board handling and storage during various stages of production and fabrication so as to mitigate moisture-induced failures....

The EMS Gateway Model - Local to Global, Seamlessly

Apr 24, 2019 | Brenda Martin

Choosing an outsourced manufacturing partner that is perfect for a new product and close to your design team is quite different to choosing a partner that can manufacture that same product in volume in lower cost locations and fulfill globally. This is where the Gateway model comes into its own. Most large EMS have structured their organizations to leverage proximity to OEM design teams in high cost regions while providing the benefits of low cost regions for volume manufacturing. The "Gateway" facility in higher cost regions provides design engineering, supply chain design, prototype, and NPI services. The goal of the Gateway is to develop an effective build recipe that can then be effectively and seamlessly transferred to one or more volume manufacturing facility that offers lower costs and direct fulfillment to consumers.

We will present a case study that highlights the value of this model and that shows some of the key elements that allow for seamless transitions from plant to plant. The Gateway model is an essential element to a successful global manufacturing model and helps ensure that products are made in the right geography....

What is the application of moisture proof dry cabinet?

Apr 11, 2019 | Climatest Symor

Are your MSD safely stored? As humidity is found to be one of the key reasons for rejected products, many manufacturers are taking measures to control the humidity to increase their production efficiency and save the cost. In the industries of semi-conductor and electronics, the key section in which the rejected products are most probably to be made is that during the heating process of SMT, the IC(e.g.,PBGA,BGA,or TQFD) is likely to crack and thus cause non-effective welding because of the humidity. Climatest Symor® auto dry cabinet is the best solution to avoid the cracking and noneffective welding by dehumidifying the surface of your components. The dry unit can be used for 20 years without replacement,and controller is calibration free within 5 years.We attach dry cabinet application with different humidity range,welcome to download....

Soldering Immersion Tin

Apr 10, 2019 | Rick Nichols, Sandra Heinemann

The stimulating impact of the automotive industry has sharpened focus on immersion tin (i-Sn) more than ever before. Immersion tin with its associated attributes, is well placed to fulfill the requirements of such a demanding application. In an environment dominated by reliability, the automotive market not only has very stringent specifications but also demands thorough qualification protocols. Qualification is ultimately a costly exercise. The good news is that i-Sn is already qualified by many tier one OSATs.

The focus of this paper is to generate awareness of the key factors attributed to soldering i-Sn. Immersion tin is not suitable for wire bonding but ultimately suited for multiple soldering applications. The dominant topics of this paper will be IMC formations in relation to reflow cycles and the associated solderability performance. Under contamination free conditions, i-Sn can provide a solderable finish even after multiple reflow cycles. The reflow conditions employed in this paper are typical for lead free soldering environments and the i-Sn thicknesses are approximately 1 μm....

Symor ESD storage dry cabinet(Working principle)

Apr 08, 2019 | Climatest Symor

Climatest Symor® adopts molecular sieve to dry air, the whole system is controlled by microcomputer, when humidity is high, It will start to absorb moisture,when the humidity reach the pre-set value, it will stop absorbing, and then discharge the water to outside the cabinet by heating,again and again by automatic control. The most effective and environment-friendly moisture-absorbing desiccant is molecular sieve, molecular sieve is the microporous crystal material synthesized by silicon and aluminium oxide. In order to keep the crystal net discharge to be zero, atoms with cations are located in the crystal structure.and the cation used in these synthetic crystals is usually sodium. At present, there are two kinds of molecular sieves widely used in the dry box industry: Class A and Class X. Molecular sieves are synthesized, shaped and activated under strictly controlled production processes. The whole controlled sythesis process can ensure consistency of the three-dimensional pore size. 3A molecular sieve pore size is 3 angstroms, 4A molecular sieve pore size is 4 angstroms; 13X molecular sieve pore size is 8.5 angstroms. The working principle of molecular sieve: Molecular sieves adsorb molecules onto the crystal surface by physical attraction force. Since 95% surface area of the molecular sieve is within aperture,it needs to screen the adjacent molecules by different size. Only small size molecules can enter into the inner adsorption surface of the molecular sieve through the crystal aperture. This selective adsorption phenomenon is called molecular sieve effect. The molecular sieve adsorption capacity and charge density (polarity) are further related to the adsorbed molecules. The molecular sieves can further distinguish which of the mixed molecules can be adsorbed and determine to what extent the charge density can allow the molecules to be adsorbed onto the crystal. Water molecules are particularly small (2.6 angstroms), that belong to highly polar molecules (very strong positive and negative electron density), and are easily adsorbed by molecular sieves, even under very low moisture condition,once the water molecules are adsorbed,they will be firmly fixed on the crystal. The environment-friendly moisture absorption device is equipped with molecular sieve. When it’s absorbing, the memory alloy controller is in tensile state, and the spring is in contractive state,which just make the valve contact the outer baffle, this insulates the outside air from inside dry box air to achieve dehumidification purpose; and after molecular sieve absorbed moisture inside dry box and become saturated, the program will automatically control the memory alloy device to shrink it so that the valve reaches the inner baffle position. Meanwhile, due to the shrinkage of the memory alloy, the spring is stretched and the valve is pulled out of the outer baffle,so that the moisture in molecular sieve will be discharged into the outside. after the dehumidifying process finished, the program automatically control and reset the memory alloy and spring,to restart absorbing status....

Database Driven Multi Media Work Instructions

Mar 25, 2019 | Tommy Fox

Work instructions are time consuming to generate for engineers, often requiring regeneration from scratch to address very minor changes. They need to be produced in varying levels of detail, with varying guidelines, for multiple stations, operators and lines. Minor component, station or process changes – down to the modification of an individual BOM component – can cause headaches when attempting to maintain consistency across multiple work instructions that are touched by the change.

The solution presented here improves efficiency and saves engineering time by making use of a database driven approach. Manufacturing details, component information, process guidelines, annotations, machine-specific data, and more can be stored in one central database. Any information stored in this single repository can then be modified quickly in one location and automatically propagate seamlessly throughout multiple work instructions. These can be instantly printed out or displayed on screens at appropriately affected stations with the simple click of a button, as opposed to regenerating from scratch, or going in and reviewing many documents to find and update with the change....

Embracing a New Paradigm: Electronic Work Instructions (EWI)

Mar 15, 2019 | Jeffrey Rupert, Travis Loving

While there have been quite dramatic and evident improvements in almost every facet of manufacturing over the last several decades owing to the advent and mass adoption of computer automation and networking, there is one aspect of production that remains stubbornly unaffected. Massive databases track everything from orders, to inventory, to personnel. CAD systems allow for interactive and dynamic 3D rendering and testing, digital troubleshooting, and simulation and analysis prior to mass production. Yet, with all of this computational power and all of this networking capability, one element of production has remained thoroughly and firmly planted in the past. Nearly all manufacturing or assembly procedures are created, deployed, and stored using methodologies derived from a set of assumptions that ceased to be relevant fifty years ago. This set of assumptions, referred to below as the “Paper Paradigm” has been, and continues as the dominant paradigm for manufacturing procedures to this day. It is time for a new paradigm, one that accounts for the vastly different technological landscape of this era, one that provides a simple, efficient interface, deep traceability, and dynamic response to rapidly changing economic forces.

This paper seeks to present an alternative. Instead of enhancing and improving on systems that became irrelevant with the invention of a database, instead of propping up an outdated, outmoded and inefficient system with incremental improvements; rewrite the paradigm. Change the underlying assertions to more accurately reflect our current technological capability. Instead of relying on evolutionary improvements, it is time for a revolution in manufacturing instructions....

An Investigation Into The Durability Of Stencil Coating Technologies

Mar 13, 2019 | Greg Smith, Tony Lentz

It is well documented that Nano coatings on SMT stencils offer many benefits to those assembling PWBs. With reduced standard deviation and improved transfer efficiency nano coatings can provide, there is also a cost. As PWB assemblers work to justify the return on investment, one key question continues to arise. What is the durability or life of these coatings and what can be done in the print process to maximize the life of the coatings?

This paper addresses durability of the coatings in relation to the number of print cycles and underside wipe cycles applied as well as materials used on the underside wipe process. Different parameters will be applied and data will be collected. The results of this study will be summarized to help those using or considering the use of these nano coatings to improve their print process and suggestions will be given to maximize the life of the coatings....

Method for detecting electronic components quickly www.seamarkxray.com Contact:Joy Tel/WhatsApp/wechat:+86 18779975930 X-ray is a kind of light with super penetrating power, which can directly penetrate the appearance of the product and directly reach the internal structure of the product. It can play a very important role in the identification of the internal structure of the product. At present, high imitation products are endless, many high Imitation products have similar appearance, but the internal structure design is different, especially the precision products, it is impossible to disassemble at will, so only the advanced technical means can be used to distinguish the product details. Now, the non-destructive testing ( NDT ) method has X-ray inspection machine and ultrasonic detection, magnetic particle testing, NDT x ray detection are as follows: For example, the internal structure of several electronic components is different: Terminal 3D detection: IC chip detection: The chip to be tested and the genuine chip are compared under the X-ray inspection machine.

Compared with manual SMD counter machine, Advantages of X-ray SMD counter

Mar 08, 2019 | Joy Rong +8618779975930 info@seamarkxray.com

Compared with manual SMD counter machine, Advantages of X-ray SMD counter I believe that many companies have experienced the mid-year inventory and year-end inventory. For electronic companies, the statistics of electronic components are very time-consuming, scattered small components, making the inventory of personnel time-consuming and laborious, seriously affecting the quality of work. And the efficiency of the enterprise, the X-RAY spot machine can solve these problems very well. Advantages of X-ray SMD counter: 1.No need to disassemble the package, component reel raw materials directly into the warehouse, directly inventory 2. It can better maintain the integrity of the product without affecting the moisture and pollution of the product. 3. Reduce inventory staff. It can directly arrange one or two Staff to operate the X-ray spotting machine to increase the counting speed and achieve higher efficiency; The inventory data can be directly uploaded to the enterprise ERP system, which is very helpful for all departments of the enterprise to understand the quantity of the products, especially the production-related operators.

Effect of Encapsulation Materials on Tensile Stress during Thermo-Mechanical Cycling of Pb-Free Solder Joints

Mar 06, 2019 | Maxim Serebreni, Dr. Nathan Blattau, Dr. Gilad Sharon, Dr. Craig Hillman

Electronic assemblies use a large variety of polymer materials with different mechanical and thermal properties to provide protection in harsh usage environments. However, variability in the mechanical properties such as the coefficient of thermal expansion and elastic modulus effects the material selection process by introducing uncertainty to the long term impacts on the reliability of the electronics. Typically, the main reliability issue is solder joint fatigue which accounts for a large amount of failures in electronic components. Therefore, it is necessary to understand the effect of polymer encapsulations (coatings, pottings and underfills) on the solder joints when predicting reliability.

This paper presents the construction and validation of a thermo-mechanical tensile fatigue specimen. The thermal cycling range was matched with potting expansion properties in order to vary the magnitude of tensile stress imposed on solder joints...

The Influence of Clean Air on the Value-Added Chain in Electronics Production

Feb 25, 2019 | ULT

“The idea of the value chain is based on the process view of organizations, the idea of seeing a manufacturing (or service) organization as a system, made up of subsystems each with inputs, transformation processes and outputs”.[1] The definition of a value-added chain by Michael E. Porter is one of many to be found in reference books, works and on websites. In principle, it involves a sequence of activities, executed by a manufacturing company to develop, produce, sell, ship, and maintain products or services. Three main parameters essentially influence a value-added chain: Direct activities − research, development, production, shipment etc. Indirect activities − maintenance, operation, occupational safety, environment etc. Quality assurance − monitoring, test/inspection; quality management etc. In particular, indirect activities and quality assurance generate a greater part of the costs in product manufacturing. This article principally focusses on the indirect activities, among them air purification....

The Impact of New Generation Chemical Treatment Systems on High Frequency Signal Integrity

Feb 20, 2019 | Jim Fuller, Sanmina-SCI; Karl Sauter, Oracle Corporation; Scott Hinaga, Cisco; Tian Qingshan, Huawei; John J Davignon, HDP User Group; Brian Butler, Introbotix; Ted Antonellis, Michael Coll, John Marshall, John Marshall, MacDermid Enthone; Joseph Smetana,

The High Density Packaging (HDP) User Group has completed a project evaluating the high frequency loss impacts of a variety of imaged core surface treatments (bond enhancement treatments, including chemical bonding and newer low etch alternative oxides) applied just prior to press lamination. Initial high frequency Dk/Df electrical test results did not show a strong correlation with any of the methods utilized within this project to measured surface roughness. The more significant factor affecting the measured loss is the choice of pre-lamination surface treatment. Most of the new chemical treatment systems outperform the older existing systems which depend upon surface roughness techniques to promote adhesion....

Influence of Copper Conductor Surface Treatment for High Frequency PCB on Electrical Properties and Reliability

Feb 13, 2019 | Seiya Kido, Tsuyoshi Amatani

Development of information and telecommunications network is outstanding in recent years, and it is required for the related equipment such as communication base stations, servers and routers, to process huge amount of data in no time. As an electrical signal becomes faster and faster, how to prevent signal delay by transmission loss is a big issue for Printed Circuit Boards (PCB) loaded on such equipments. There are two main factors as the cause of transmission loss; dielectric loss and conductor loss. To decrease the dielectric loss, materials having low dielectric constant and low loss tangent have been developed. On the other hand, reducing the surface roughness of the copper foil itself to be used or minimizing the surface roughness by modifying surface treatment process of the conductor patterns before lamination is considered to be effective in order to decrease the conductor loss. However, there is a possibility that reduction in the surface roughness of the conductor patterns will lead to the decrease in adhesion of conductor patterns to dielectric resin and result in the deterioration of reliability of PCB itself.

In this paper, we will show the evaluation results of adhesion performance and electrical properties using certain type of dielectric material for high frequency PCB, several types of copper foil and several surface treatment processes of the conductor patterns. Moreover, we will indicate a technique from the aspect of surface treatment process in order to ensure reliability and, at the same time, to prevent signal delay at the signal frequency over 20 GHz. ...

Optical Bonding

Jan 10, 2019 | Scheugenpflug

We notice that the quantities of material that are to be dosed are becoming more and more divergent. In addition to large media volumes, small and very small quantities are also increasingly coming into focus. For example autonomous driving: These vehicles already produce an immense amount of data today. When potting the associated sensors, cameras, and ECUs, it is important to ensure a precise and repeatable media application – even with volumes of only 0.03 ml. In contrast, when high-voltage batteries for electric cars are potted, 5 to 10 litres of heat-conducting paste are required per vehicle – and the trend is rising. Optical bonding used in display production, on the other hand, is in the medium volume range. The challenge now is to cover the entire volume spectrum reliably and in compliance with the required cycle times. This is remedied by a modular system of scalable modules, which offers the customer the necessary flexibility and enables him to plan a system according to his needs....

An Investigation into Lead-Free Low Silver Cored Solder Wire for Electronics Manufacturing Applications

Jan 09, 2019 | Shantanu Joshi, Jasbir Bath, Kimiaki Mori, Kazuhiro Yukikata, Roberto Garcia, Takeshi Shirai

The electronics industry has widely adopted Sn-3.0Ag-0.5Cu solder alloys for lead-free reflow soldering applications and tin-copper based alloys for wave soldering applications. In automated soldering or rework operations, users may work with Sn-Ag-Cu or Sn-Cu based alloys. One of the challenges with these types of lead-free alloys for automated / hand soldering operations, is that the life of the soldering iron tips will shorten drastically using lead-free solders with an increased cost of soldering iron tool maintenance/ tip replacement. Development was done on a new lead-free low silver solder rework alloy (Sn-0.3Ag-0.7Cu-0.04Co) in comparison with a number of alternative lead-free alloys including Sn-0.3Ag-0.7Cu, Sn-0.7Cu and Sn-3.0Ag-0.5Cu and tin-lead Sn40Pb solder in soldering evaluations....

Casting NDT inspection Original: Casting NDT inspection Casting refers to the casting of metal. In the process of manufacturing, due to the gas generated during the cold casting and forging process, many small pores are easily caused in the casting, which has a certain influence on the overall tightness of the casting. Casting NDT inspection method: There are problems with castings. If some problems are more serious, the quality defects of the products will be increased. Generally, non-destructive testing equipment is used in the market to detect the quality of castings, such as X-RAY, ultrasonic, etc. Loose casting: During the solidification process of the casting, due to solidification shrinkage or the presence of gas, the castings produce voids, resulting in insufficient tightness of the casting; Impurities: Castings are mixed with other fine particles, foreign matter, etc., affecting product quality; Internal defects: After the castings are manufactured, the process technology lags behind, causing defects such as bubbles, cracks and delamination of the castings; Small defects won’t affect the normal use of the product, but for the precision of scientific research, the product’ quality is very important, in order to ensure the quality of the casting, X-RAY inspection equipment, ultrasonic non-destructive testing can be used to test the casting.

Risk Mitigation in Hand Soldering

Jan 02, 2019 | Robert Roush

Failed solder joints remain a constant source of printed circuit board failure. Soldering is the bonding of metallic surfaces via an intermetallic compound (IMC). The interaction between thermal energy delivery, flux chemistry, and solder chemistry creates the solder bond or joint. Today, reliability relies on visual inspection; operator experience and skill, control of influencers e.g. tip geometry, tip temperature, and collection and analysis of process data. Each factor involved with the formation of the solder joint is an element of risk and can affect either throughput or repeatability. Mitigating this risk in hand soldering requires the identification of these factors and a means to address them....

Process Optimization for Fine Feature Solder Paste Dispensing

Dec 19, 2018 | Maria Durham, Greg Wade, and Brandon Judd; Indium Corporation, John Boggiatto; ITW EAE - Speedline Technologies

With the rapid trend towards miniaturization in surface mount and MEMs lid-attach technology, it is becoming increasingly challenging to dispense solder paste in ultra-fine dot applications such as those involving chip capacitors or BGA packages, as well as dispensing ultra-fine lines in MEMs lid-attach applications. In order to achieve ultra-fine dots and fine line widths while dispensing solder paste, both the solder material and dispensing equipment need to be optimized. Optimizing the equipment can be very challenging, as there are many input variables that can affect the dispense quality of the solder paste.
