SMT fine pitch connector having oxidation on lead and P&P machine keep rejecting the part. Is there any alternative way to reduce the part throw out rate without jeopardize the placement accuracy? Or is it possible to re-coat the connector lead or an

Thanks for the reply Larry, I've checked the springs and they look ok, I have swapped them just to make sure. What I have noticed while manually moving the head up & down, there seems to be a sticking point, I have checked the rails and they are clea

Hege, the Nano coating goes on the opposite of the squeegee side of the stencil. I don't know if the cleaning paper is able to remove it little by little with the time, but I never refreshed my stencils with Nano coating and they work just fine. How

I am not trying to be critical but, you didn't even say Fuji CP-6 problem. There are CP-6, CP-642, and CP-643 machines, are asking 2 model as 642? Anyway, slow the cam speed down in the proper to 40 or 50%. If the problem goes away check the mainte

I am not aware of any correlation that temperature and pressure is a good indicator of board cleanliness. You can drop a thermometer into the tank to verify the temperature. Water cleanness/Ph are more important. If you are truly worried about board

There are two IR sensor (one for tipdown detector and other one for tipup detector) for each tip in each head. You should check infrared sensor for Head2 tip1, that cause may be by dirty between IR emitter and IR receiver. Just clean it and try to ru

A trick I used to use doing RF design was to have on the edge of a panel, a stripline that I could hook up to a Network Analyser to check board impedance. You could do this to verify if the fault is in the no wash process or a board manufacture proce
