Stencil Printing 101
Printing is an extremely critical part of the assembly process and many defects that are created in the SMT process begin in the printing stage. Typical causes of these defects are poor alignment between the substrate and the stencil, incorrect paste chemistry, or inconsistent/excess/insufficient solder paste deposits. Understanding correct printing optimization is crucial to reducing defects and increasing yield. Industry veteran Peter Biocca, Kester ITW, guides you through this informative online course providing a basic understanding of the stencil printing and troubleshooting processes.
