We began placing chip resistors over vias as a rework process several years ago. We then "progressed" to printing paste over vias and placing directly onto the paste on one particular design. The solder paste sometimes all flows into the holes. The subsequent wave solder process also sometimes robs the chip resistor of solder. We explicitly inspect these locations following wave soldering. No field problems have resulted in this home/office modem product. ______________________________ Reply Separator _________________________________ Subject: [TECHNET] 0603's on vias Author: "\"TechNet Mail Forum.\" <[log in to unmask]>, Frank Hinojos" <[log in to unmask]> at ftl03
