Hello Carlo,
can ProTEK A2 be patterned ? From this page,
http://www.brewerscience.com/?id=587
it seams that ProTEK A2 is not photosensitive. So how do you suggest to
ues it ?
Another question: do you have any informations about resistance of ProTEK
A2 to BOE etch (1 part of HF and 7 parts of NH4F) ?
Best regards,
Andrea
