Printing process and trouble with metal stencils
2022年9月12日 · In this page, we will explain how to print out solder paste using a metal mask. There are two main types of stencil used in SMT process. Metal stencil with high printing accuracy is generally used for solder paste printing in the SMT process.

We provide high-precision, high-quality metal masks by using three types of treatment: laser, additive, and etching processes. This can be used not just for plates for printing, but in a wide range of fields, from deposition and sputtering applications …
BON MARK Chemical etching stencil For step-down or step-up stencil
STEP-DOWN Stencil Used when printing the pattern with small and large apertures at one time . (Large ones need enough amount of paste, but small ones need less for avoiding the “bridge”, “solder ball spreading” problems.)

What is 'metal mask' here? - Electrical Engineering Stack Exchange
2021年3月24日 · Metal mask in this case I believe refers to the solder paste stencil, given it specifies a thickness. And solder paste stencils are usually made of metal, except for the very cheapest (you can get mylar ones for one-off designs, but they can't usually be used more than a handful of times).

Stencils can be classified into three major categories. 1. Selectively etched mesh / emulsion screen. 2. Metal (Alloy 42, brass, or stainless steel) mask. 3. Flexible metal mask. The selectively etched mesh /emulsion type is made the same way as the screen, but the openings are completely etched out.
