Hello Sr.Tech, There have been two types of nozzles made by Fuji for 0201's one was a 1mm tapered to .4mm and the other has a straight .4mm tube. Has one superceded the other and if you have used both types, did one work better than the other? Asking

We have some new customers that are requiring class 3 IPC standards, and my question is, how would that translate into a labor rate increase as compared to class 2 rates? I'm assuming the labor quote would increase by at least 15-20%, if not more. An
