Cold soldering has become the highest frequency problem found during pre-shipment electroluminescence inspection of PV ...

When you learn to solder, you are warned about the pitfalls of creating a solder joint. Too much solder, too little solder, cold joints, dry joints, failing to “wet” the joint properly ...

Electromigration failure of interconnected solder joints. Finally, electromigration is the most insidious of all, as it does not require any external influences. The ultimate effect of ...

Quality control and inspection are an integral part of making reliable solder joints. Their primary function is the continuous monitoring of all the parameters that contribute to the reliability of ...

The process involves melting a filler metal (solder) and flowing it into a metal joint. For this reason, it is important for the filler metal to have a lower melting point than the metals being joined ...

When defects cropped up in packages at various steps during manufacturing ... For example, advanced packages have a multitude of bumps with hard-to-see buried solder joints. For this application, a ...
