as we speak about dry film soldermask and buying those,!
first of all it has a limmited time of use - shelf life is six months
from date of manufacture.
on this moment my film's are about one year old, and stil works fine
-brand is Dynachem®
Dynachem dm (soldermask) neet a strong vacuum unit for fine result
and 5000 (photopolymer)
My 2 cents
