Shielding electronic systems against electromagnetic interference (EMI) has become a hot topic. Technological advancements toward 5G standards, wireless charging of mobile electronics, in-package antenna integration, and system-inpackage (SiP) adoption are driving the need to apply more effective EMI shielding and isolation to component packages and larger modules. For conformal shielding, EMI shielding materials for exterior package surfaces have mostly been applied with a physical vapor deposition (PVD) process of sputtering, leveraging front-end packaging technologies to back-end packaging applications. However, sputtering technology challenges in scalability and cost along with advancements in dispensable materials are driving considerations for alternative dispensing techniques for EMI shielding.

Understanding The Crucial Role Of Dust Collectors In PCB Depaneling Machines Precision is paramount in PCB manufacturing, but it must go hand in hand with cleanliness. The intrusion of dust and debris can wreak havoc on delicate electronics. This article explores the pivotal role of dust collectors, their operation, and their necessity for various PCB depaneling machines. The Dust Collector's Crucial Function Dust collectors, also known as dust extractors, play an indispensable role in PCB manufacturing. When a PCB depaneling machine or a Laser PCB Depaneling machine is in operation, it generates a significant amount of dust. The dust collector promptly engages its vacuum motor to suction fine particles off the PCB, directing them to a collector equipped with a filtration system. Which Models Of PCB Depanelers Require Dust Collector? Several PCB depaneling machines necessitate dust collectors to ensure precision and cleanliness, including: I.C.T-5700 Offline Depaneling Machine, high precision, easy manual operation, dual platform, high efficiency. I.C.T-IR350 In-line depaneling machine, high precision, rapid operation, suitable for integration into the SMT production line for Industry 4.0 and AI automated production. I.C.T-LCO350 Laser cutting ensures cutting accuracy of 0.002, ideal for precise cutting requirements. I.C.T-100A Desktop PCB depaneling machine with compact size and high precision, suitable for smaller-scale operations. The Science Behind PCB Dust Collectors To prevent charged dust particles from adhering to PCBs, PCB depaneling machines are equipped with ionizing guns. These devices emit ions that neutralize static charges, making dust particles less likely to stick to freshly cut PCBs. The Vacuum Effect: Suctioning Away Dust During PCB depaneling, a cloud of dust is produced. The dust collector utilizes a robust suction system, often powered by vacuum motors, to draw dust away from the work area. Collected dust is transported to a designated collection point within the dust collector. A Difference In Design: I.C.T-5700 Vs. I.C.T-IR350 The placement of the dust collection apparatus distinguishes PCB depaneling machines. I.C.T-5700 has a bottom-mounted system capturing falling dust, while I.C.T-IR350 features a top-mounted system preventing dust settling on the work surface. This strategic difference ensures efficient removal of dust and debris, guaranteeing a clean and precise manufacturing process. Check: If you want to learn about the comparison of I.C.T-5700 and I.C.T-IR350. The Importance Of Filter Replacement The efficiency of a dust collector relies on its filter, necessitating periodic replacement every 1-3 years, depending on usage frequency. Regular filter maintenance ensures optimal performance.

For the separation of ionic species, ion chromatography (IC), a type of liquid chromatography, is the method of choice. The most critical component of this technique is the separation column, which is selected based on factors that include the specific analytes of interest, the sample type and the required detection levels. This article outlines the column parameters that impact the separation of charged species in solution using ion-exchange chromatography and the developments that have continued to redefine what is possible with an IC system.

With the push for ever improving performance on semiconductor component I/O interfaces, semiconductor components are being driven into a realm which makes them more sensitive to electrostatic discharge, potentially increasing in sensitivity by 50% every 3-5 years. Today, the majority of modern day semiconductor components are being designed to meet 250Volts of charge device model sensitivity, and that could decrease to 125Volts in the next 3-5 years, and could again decrease to 50Volts-70Volts in the following 3-5 years. The entire electronics industry must prepare for this challenge.

On September 14, 2010, the late Shannon Wren, owner of VisionTech Components ("VisionTech"), and Stephanie McCloskey, VisionTech's Administrative Manager, were arrested during the execution of search and seizure warrants issued against the pair by the United States government after evidence connected them to the sale of counterfeit parts to the U.S. Navy, defense contractors and others. A ten-count indictment charged McCloskey with conspiracy, aiding and abetting in violation of Title 18 United States Code, Sections 371 and 2; trafficking in counterfeit goods, in violation of Title 18 United States Code, Section 2320; and mail fraud, in violation of Title 18 United States Code, Section 1341. McCloskey pled guilty to conspiracy and aiding and abetting for her role in the scheme.

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.
