IPC VT-35: Solder Paste Printing - Defect Analysis and Prevention
Second tape in a series (with IPC-VT-34) defines typical defects associated with solder paste printing. It discusses probable causes and offers recommended solutions.
Reviews: * Lack of Coverage
* Solder paste volume / print shape
Adjustments include kneading paste, squeegee pressure and speed, downstop, snap-off and temperature.
Stresses the inportance of preventative maintenance.
