Solder joint faults can be described with a single word – pernicious. Solder joints connect the BGA package, containing an FPGA (Field Programmable Gate Array) core, to the PCB (Printed Circuit Board) ...

Many factors affect the long-term reliability of ceramic-substrate-based chip resistors. Among those are changes in resistance due to soldering, temperature changes, or even the expected shifts in ...

According to an article in EMT Worldwide, it’s not uncommon to find lead-free fillet tears in plated through hole joints. The article presents photos that show two examples of these phenomena, both ...

Solder is the conductive metal glue that one uses to stick components together. If you get the component and the PCB hot enough, and melt a little solder in the joint, it will stay put and conduct ...
