| Has anyone had issues where bottomside double reflowed smt has fallen off in the wave when using voc-free flux? I have verified the hotter profile was not the issue by using an alcohol based flux with no problems.This voc-free flux is also not caus

Currently, I am having problems with a AMP Mictor connector at the wave process. These connectors have both SMT leads(topside) and thru-hole leads. Even though we have re-designed the board for via issues. We still see some of the SMT leads re-fl

Hello everyone out there, I have been working in the SMT process for a couple o years now, and now I'm partly responsible for the turret head component mounting process. We are about to buy new equipment and I want to do a capability study of this m

Trying to place PTH components with an SMT machine is possible but maybe not plausible. Would you have to buy specialized tools and equipment for the job ( gripper nozzles ). Are the machines you have capable. i.e.. Would you need camera modification

1) why is No-clean (NC) the preferred process, for BGA mounting by SMT? Probably the same reason NC is the preferred process for mounting non-area array SMT components. 2) why is water-soluble (WS) not a hot choice? There�s not reason not to use
