Improving SMT Stencil Printing YieldsPresenter: Chrys Shea
Company: Shea Engineering Services
Date Published: 4/11/2013
This 2-part webcast begins with a review of the basic mechanics of solder paste printing and the key elements of the process. The first portion continues with the general steps used to check a process that is not producing good prints, and then moves into specific defects like solder bridges, insufficient deposits, and poor print definition, showing images of the defects and discussing the most common causes of them in a typical production environment. The May, 2012 SMTA Webinar titled “Troubleshooting the Stencil Printing Process” presented similar content.
The second portion addresses process improvement techniques and how to employ the analytical capabilities of automated solder paste inspection systems to boost yields. It reviews simple experiments that can be performed quickly during production breaks to improve printing processes and prevent print defects from occurring.
