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. |
