There are a lot of things that might affect your cleaning efficiency. Paste type (no clean or w/s?), cleaning chemistry, aperture aspect ratio (aperture width/stencil thickness), "linty" wipes, etc. Another thing you need to look at is the frequency

Ummm...why not use Loctite 7360 Surface Mount Adhesive Cleaner? It's designed to remove adhesive and works great. Low oder and can be bought in 500ml cans for hand cleaning. Part# 25658. Use it why any dry wipe. Do not use alcohol to clean this

Good morning, Our automatic cleaner simply doesn�t clean. When I am inspecting clogged apertures I execute �cycle wiper� command few times. After wiping cycle apertures remain clogged. Zero effect. We tried to use solvent in production to improve cl
