Reflowed indium metal has for decades been the standard for solder thermal interface materials (solder TIMs or sTIMs) in most high-performance computing (HPC) TIM1 applications. The IEEE Heterogeneous Integration Thermal roadmap states that new thermal interface materials solutions must provide a path to the successful application of increased total-package die areas up to 100cm2. While GPU architectures are relatively isothermal during usage, CPU hotspots in complex heterogeneously-integrated modules will need to be able to handle heat flux hotspots up to 1000W/cm2 within the next two years. Indium and its alloys are used as reflowed solder thermal interface materials in both CPU and GPU "die to lid/heat spreader" (TIM1) applications. Their high bulk thermal conductivity and proven long-term reliability suit them well for extreme thermomechanical stresses. Voiding is the most important failure mode and has been studied by x-ray. The effects of surface pretreatment, pressure during reflow, solder flux type/fluxless processing, and preform design parameters, such as alloy type, are also examined. The paper includes data on both vacuum and pressure (autoclave) reflow of sTIMs, which is becoming necessary to meet upcoming requirements for ultralow voiding in some instances.

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. Dust Collectors: Keep Your PCB Manufacturing Clean And Precise Precision in PCB manufacturing is not solely about cutting-edge machinery but also about cleanliness. If you seek a dust collector for your PCB depaneling machine, contact us today to explore your options. Ensure your operations maintain cleanliness, efficiency, and meet the high standards of modern PCB manufacturing. Don't let dust compromise your precision – let's keep it clean together!

The ability to undertake non-destructive testing on semiconductor devices, during both their manufacture and their subsequent use in printed circuit boards (PCBs), has become ever more important for checking product quality without compromising productivity. The use of x-ray inspection not only provides a potentially non-destructive test but also allows investigation within optically hidden areas, such as the wire bonding within packages and the quality of post solder reflow of area array devices (e.g. BGAs, CSPs and flip chips).

Laser reflow soldering is an important technology in electronic components processing. In this paper, we presented a simple but efficient method to achieve reflow soldering process with gradient energy band created by just two parallel mirrors. The detailed influence of the variety of optical parameters on the soldering process has been analyzed by using the finite element method. And the modulation of the optical parameters on reflow soldering parameters also has been demonstrated. In our experiment, one HR mirror and one-mirror with transmissivity of 10% have been used to create a gradient energy band with an incident laser power of 50W. In summary, both the simulations and the experiments show that the typical reflow soldering profile has been acquired by the optical system. The high quality joints on both the front and rear surface of the capacitor can be acquired by just one surface radiation of the optical system.
