Case Studies - Stencil + Misprint + Squeegee

Case Studies - Stencil + Misprint + Squeegee
Perfectly clean stencils (with and without frames) and squeegees are one of the basic prerequisites for the overall quality of SMT production. It is very important to pay attention to cleaning quality, especially nowadays with the miniaturisation of components, as this is the only way to avoid subsequent production failures.

Poorly cleaned stencils with soldering paste and SMD adhesive residues result in the production of improper pre-prints the subsequent repair of which (misprint cleaning) leads to increased costs and prolongs the overall process. If you are not sure about the correct cleaning technique, please contact us and we will test your samples free of charge and recommend both a cleaning liquid and a cleaning system.

How To Clean Pumpprint from Adhesives

Our R&D team tested the most effective way how to remove uncured epoxy adhesive Three Bond 2217H from pumpprints, which can get cured in the apertures and cause a printing error.
