High Frequency Dk and Df Test Methods Comparison High Density Packaging User Group (HDP) Project

Feb 06, 2019 | Karl Sauter

The High Density Packaging (HDP) user group has completed a project to evaluate the majority of viable Dk (Dielectric Constant)/Df (Dissipation Factor) and delay/loss electrical test methods, with a focus on the methods used for speeds above 2 GHz. A comparison of test methods from 1 to 2 GHz through to higher test frequencies was desired, testing a variety of laminate materials (standard volume production with UL approval, low loss, and "halogen-free" laminate materials). Variations in the test board material resin content/construction and copper foil surface roughness/type were minimized. Problems with Dk/Df and loss test methods and discrepancies in results are identified, as well as possible correlations or relationships among these higher speed test methods....

Novel Pogo-Pin Socket Design for Automated Low Signal Linearity Testing of CT Detector Sensor

Jan 30, 2019 | Mahesh Narayanaswamy

Due to the arrayed nature of the Computed Tomography (CT) Detector, high density area array interconnect solutions are critical to the functionality of the CT detector module. Specifically, the detector module sensor element, hereby known as the Multi-chip module (MCM), has a 544 position BGA area array pattern that requires precise test stimulation. A novel pogo-pin block array and corresponding motorized test socket has been designed to stimulate the MCM and acquire full functional test data. (...) This paper and presentation will focus on the socket design challenges and also key learnings from the design that can be applied to general test systems, including reliability testing. The secondary focus will be on the overall data collection and graphical user interface for the test equipment....

AOI Capabilities Study with 03015 Component

Jan 23, 2019 | David Geiger, Vincent Nguyen, Hung Le, Stephen Chen, Robert Pennings, Christian Biederman, Zhen (Jane) Feng, Ph. D., Alan Chau, Weifeng Liu, Ph. D., William Uy, Anwar Mohammed, Mike Doiron

Automated Optical Inspection (AOI) is advantageous in that it enables defects to be detected early in the manufacturing process, reducing the Cost of Repair as the AOI systems identify the specific components that are failing removing the need for any additional test troubleshooting1-3. Because of this, more Electronic Contract Manufacturing Services (EMS) companies are implementing AOI into their SMT lines to minimize repair costs and maintain good process and product quality, especially for new component types. This project focuses on the testing of component package 03015 which is challenging for AOI....

Introduction to the manufacturing process of anti static ic tubes

Jan 20, 2019 | James tong

With the rapid development of the electronics industry, more and more components such as integrated circuits and connectors, relays, power modules, etc. need to be packaged with IC tubes. The anti static ic tubes is actually a kind of pvc plastic(reference to : What are the materials for IC tubes) profile, the size varies with the shape of the installed product, the precision requirement is high, the wall thickness should be controlled within ±0.1mm, and the surface is required to have no impurity spots, smooth and transparent. The IC packaging tubes produced by Sewate Technology Co., Ltd. are extruded. The typical process flow is: extrusion, vacuum adsorption setting, traction, fixed length cutting and directional discharge, deburring, immersion antistatic liquid, drying, testing, packaging and storage ...

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....
