Evaluation of Under-Stencil Cleaning Papers

Lars Bruno; Ericsson AB

Solder paste screen printing is known to be one of the most difficult processes to quality assure in Printed Board Assembly (PBA) manufacturing. An important process step in solder paste screen printing is the under stencil cleaning process and one of the key materials in this process is the cleaning paper1. This, often neglected, material affects the cleaning process and thereby also the print quality. It is therefore important to perform tests of different cleaning papers before one could be chosen.

This article describes how cleaning papers can be tested and it also tells how big differences it can be between different materials.
