  • Statistical process control of solder paste stenciling using a replicated solder paste feature distributed across a printed circuit board
    Publication number: 20080083816
    Abstract: Methods and systems for improving a solder paste stenciling process include obtaining data pertaining to solder paste deposits on a printed circuit board, the solder paste deposits deposited by a solder paste stenciling process through multiple identical apertures of a solder paste stencil, statistically analyzing the data, and correlating the data with a plurality of solder paste stenciling process problems to identify at least one solder paste stenciling process problem in the solder paste stenciling process.
