Class 1, 2 & 3 Defect if land is lifted away from the PCB surface more than the thickness of the land. Process Indicator Class 1, 2 & 3 if land is lifted at all but less than the land thickness. Gregg Owens -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Cedric ORAIN Sent: Tuesday, May 11, 2010 2:23 PM To: [log in to unmask] Subject: [TN] Pad lifting during manual soldering Hello all, We've just achieved a critical process analysis on a PCBa for high end market. We found that the land of some of the plated through hole appeared slightly lifted from the PCB surface. The component was hand soldered with lead free alloy (SAC305). Is pad lifting is acceptable? Or to what extend does it still acceptable? I could post a picture, but I have to admit that I didn't know where or how?
