Well if you don't want the Chinese sh!tbox answers, don't ask on here. Go talk to the the semi-professional, working out of their garage people over on EEVBlog. There is a reason the anti-chinese comments come up, it is because in relative terms, the

I think you are going to struggle without a laser designed for PCBAs (Asys, XJ Link etc) as they are designed to just burn into the resist and give good defininition, then readback to know you have a good mark. Key tips for our experience: Datama

Hello and good morning. I've recently encountered an issue with a DEK tool and no one is able to remedy it. During the initializing phase, the table begins "bouncing" up and down and never stops, halting the process. There's a pass through proximit

I've never lost memory in a BGA from heat removal. However we can create a profile on our BGA rework stations to remove using bottom heat only. This exposes the BGA body to temperatures of around 190 to 200C. I have a colleague that has a machine
