Void is the presence of air bubble in a solder joint, which affects the mechanical strength, thermal conductivity and electrical properties of the solder joint. Under the same PCB and device ...

Melting point: determines the soldering temperature of the solder paste, and the melting point of tin powder of different compositions is different. Particle size: affects the printing performance and ...

Granted, such a tool is a lot more work than tape and spare PCBs, but if you do a lot of SMD work, it may be worth the effort. It’s certainly less effort than a solder-paste dispensing robot.

“This typically occurs when one solder paste deposit reflows before the other,” said FCT. “It is commonly found on circuit boards that have a ground plane attached to one end of a small component, ...

[John] got a shiny new solder paste dispenser for a steal, and before he hooked up the tool, he decided to take a look inside to make sure everything was on the up and up. Aside from a few ...
