Definition for a new defect

2017/2/28 4:28:01

Hi, Last Friday, we had a new defect in our line. We found a nice and shiny solder fillet completelly attached to some component leads (in a SPLCC 84) but the solderjoints were not solder to the pads. (Hasl finishing)

Any idea ?? Some contamination maybe ?? or profiling problem ??

Thanks
