ASAHITEC's emulsion glass masks, on which circuit patterns are drawn as required by using the up-to-date
laser photo-plotter, help you form highly elaborate circuits on various boards.

 

Since this mask is made of glass, the dimensional stability is so high, all you have to do in dimensional control is to keep an eye on temperature.

This high-resolution type mask has high reproducibility almost comparable to that of "chromium glass mask" and also the industry's best resolution with
L/S = 5μm/5μm.。

We are also handing chromium glass mask.
