Sn-3.0Ag-0.5Cu/Sn-58Bi composite solder joint assembled using a low-temperature reflow process for PoP technology

Package-on-Package (PoP) is a popular technology for fabricating chipsets of accelerated processing units. However, the coefficient of thermal expansion mismatch between Si chips and polymer substrates induces thermal warpage during the reflow process. As such, the reflow temperature and reliability of solder joints are critical aspects of PoP. Although Sne58Bi is a good candidate for low-temperature processes, its brittleness causes other reliability issues. In this study, an in-situ observation was performed on .. ...

Optimising Solder Paste Volume for Low Temperature Reflow of BGA Packages

The need to minimise thermal damage to components and laminates, to reduce warpage-induced defects to BGA packages, and to save energy, is driving the electronics industry towards lower process temperatures. For soldering processes the only way that temperatures can be substantially reduced is by using solders with lower melting points. Because of constraints of ...

Assembly Process Feasibility of Low/No Silver Alloy Solder Paste Materials

Sn3.0Ag0.5Cu (SAC305) is the most popular near eutectic lead-free alloy used in the manufacturing processes. Over the last several years, the price of silver has dramatically increased driving a desire for lower silver alloy alternatives. As the results, there is a significant increase in the number of alternative low/no silver lead-free solder alloys ...

What range can it operate? -- What voltage range can the AD5245BRJZ5-RL7 operate on, and why is it important? Details:https://www.cff-chips.com/productdetail/ad5245brjz5-rl7

Yamaha YG100/Assembleon Opal XII camera brightness -- We operate a pair of Yamaha YG series pick and place machines (I believe also known as Assembleon Opal XII). One of them has nice, bright images from the cameras, while on the other the images are very dull. It's starting to cause problems with recognition on small parts like 0402 (imperial). We notice poor brightness from both the front and rear line scan cameras used to vision components, so it can't be the camera itself. The camera lighting LEDs are controlled by specific separate boards, so it can't be an issue there or we would see a different result front and back. Our second machine has the same cameras and we see a much brighter camera image and no visioning issues. Does anybody have any suggestions of where else we should be looking?
