The wetting performances of these solder pastes on different substrates were studied under various reflow profiles. The test results of solder ball, slump and printing properties indicate that with a ...

This project, sent in by [Henk], goes through a few different ways to make a solder stencil using a vinyl cutter, a CO2 laser, and a fiber laser. The project starts with identifying a method to ...

The experiments were carried out with a different ratio between the standard and low-temperature pastes. It was measured whether changing the amount of bismuth in the solder paste changed the amount ...
