I am doing lead free testing on a Vitronics selective machine with a 4 mm nozzle. The finishes I am testing are ENIG, ImSn, and ImAg. The problem I am encountering is achieving good top side wetting. Has anyone had any luck with this type of an ap

Hello experts, Here is my problem: I have a board that has smt parts on one side and TH parts on the other. We designed special pallet for wave, but the pallet itself is 15mm thick, so we are still seeing some defects. Have any of you tried to find

A thorough analysis is in order because laser point-to-point soldering lacks the flexibility of the bottom sided miniwave systems. My experience showed that heating profiles could be grossly affected by color temperature and thermal mass. This can be

Thank you guys. I will check this stuff out. It quite possibly could be something we have done wrong. Thanks again for the feedback

I was wondering if any of you fine folks had a trick to changing out nozzles for a Pillerhouse Jade Handex. The tool they gave us when we purchased the machine is inadequate at best. I have tried heating the nozzle up, to no avail. Just wondering if

Beej, The tool supplied works well as long as the bath is up to temp and the nozzle tip was not cross threaded when fitted. Did you apply a small amount of the anti seize paste before the nozzle tip was fitted? I have seen dry tight threads if not ap
