Metal Mask





Steken use the Photo Etching technology to make precision metal mask.

We use Japan technology to develop photo etching machine to make the products.The hole shape could as horn,and the edge is smooth.It is easy for solder to demould.

The Metal mask specification as follow:

1.Position precision:≦±5μm

2.Roughness:≦±2μm

3.Metal thickness:0.02㎜~1.0㎜

4.Minimize hole size:50μm

5.Apply on any kinds of solder and different machines requirement。

6.The products with micro-vias have smooth edge,Electrolytic polishing process help fine pitch pattern demould easily.

7.Half-etching process can make STEP UP/ STEP DOWN mask. Steken has the SMT know how over 20 years to develop special mask. It can display multiple layer on the mask to satisfy more complicate SMT process in the future.

●Normal Chemical Etching

The edge is not smooth for normal chemical etching. The center will be concave or convex. It will make solder demould well.
