Through the pads of conncector(50pin) were printed full solder paste, the solder paste of about 2-5 pads follow to bottom of the connector 2-5 pins, the 2-5 pads outside of connector no any tin after reflow. Is this PCB problem? I can supply failur

It sounds like a board issue. With the current site software, you can not attach pix. You need to post the pix on another site [eg, imageshack, villagephotos, etc] and then post the link here. Or if only a couple of folk are interested, just email

A touched-up solder joint is never as reliable as one soldered correctly by machine. Touching up adds more heat thereby increasing the thickness of the intermetalic bond. Our goal is to have the thinest intermetalic bond in our solder joints. The int

Bruno The real question about your troop using Kester 951 wave solder flux on boards is: how is the flux applied and controlled. See, when you apply this flux with your wave solder fluxer, it is ideally applied in a metered fashion with your fluxer

By definition, no clean solder can be not-cleaned. The solder/flux are formulated to result in low ionic-contamination, hence, no cleaning. I have, however, always had at least one customer that requests their no-clean solder get cleaned. No-clean
