In SMT stencil cleaning roll cores, mainly two different materials, PVC or paper, are used. Other materials, such as polypropylene, are rarer. Here we will review the pros and cons of the different materials. But it's not enough to consider the core as a separate product, we must also look at the whole picture to make the right choice. But let’s start with a review of the different core materials in this article.

Solder paste screenprinting 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 screenprinting is the under stencil cleaning process and one of the key materials in this process is the cleaning fabric.  This IPC report describes how cleaning fabrics can be tested and it also tells how big differences it can be between different materials.
