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 ...

A PCB stencil provides a template that goes over the PCB and has openings only where solder paste needs to be applied. With a glob of solder paste and a squeegee, an entire board can have the solder ...

Mini LED chips can measure as small as 50μm × 100μm, with pad spacing as narrow as 5-50μm, demanding extreme precision in ...

Preventing plating and soldering voids is about testing new manufacturing processes and analyzing the results. Plating and soldering voids usually have an identifiable cause, such as the type of ...
