Hi, There is lots of threads on this, so I would search these, and then do some reading. Then once you have some brands in mind, call the suppliers of this equipment and get some demos to learn about how each machine works. There is lots of differen

If I was trying to sell you something I'd be more direct, i'm more interested in peoples views of this testing then I am in convincing you to use it. In addition, you're both in America and i'm in New Zealand, so what am I going to sell you? I didn'

Hello everybody, I had not noticed until yesterday this situation. Whenever the wave operator has a problem with a PCB (i.e. lifted parts, misprayed flux, etc.) they wave solder the PCB again "to fix it". The problem is that PCBs do not look pretty

Please note that pin holes and blow holes are not always defects. The latest IPC 610A Rev D workmanship standard has them as process indicators- depending on Class. I don't have the document handly while writing this. It would be good to look that up

"I just need better reasons than it [...] increases defect probability." If that's not enough, you have bigger problems. Have you seen any rework/repair that was generated by this handling gem? Does your company profess to build to IPC specificati
