... The most important attribute of a stencil is its release characteristic. In other words, how well the paste releases from the aperture. The paste release, in turn, depends on the surface characteristics of the aperture wall and stencil foil. The recent introduction of new technology, nano-coating for both stencil and squeegee blades, has drawn the attention of many researchers.
The past few years have brought PCB assemblers a multitude of choices for SMT stencil materials and coatings. In addition to the traditional laser-cut stainless steel (SS) or electroformed nickel, choices now include SS that has been optimized for laser c
This paper addresses durability of the coatings in relation to the number of print cycles and underside wipe cycles applied as well as materials used on the underside wipe process. Different parameters will be applied and data will be collected. The results of this study will be summarized to help those using or considering the use of these nano coatings to improve their print process and suggestions will be given to maximize the life of the coatings.
... The effectiveness of both the nanocoatings as well as the higher end stainless steel materials, which have been heretofore studied in controlled printing environments, will be evaluated for their impact on the hand printing process. The purpose of the study was to determine the effectiveness of select nanocoating materials as well as certain high end stainless steel stencil materials as they relate to the manual SMT printing process. A variety of nanocoatings were applied to SMT metal stencils and solder paste volume measurements were taken to compare the effectiveness.
Ultrasonice Automatic Stencil Cleaner -- Team, Looking for best cost effective option for Automatic Stencil Cleaner (Ultrasonic) for Cleaning the stencils after solder paste printing process. Max size of stencil is 32" X 32".Please suggest.
Using Oxygen Absorbers/Scavengers -- Hi SMTnet. I have a series of sensitive parts and solder preforms which degrade when exposed to oxygen and moisture. It seems the standard way of protecting these components is to use a nitrogen purged cabinet as storage. This seems to use a lot of nitrogen as there is normally a constant flow of nitrogen through ... Thanks!
