Stainless Steel Surface Pre-Treatment for Dry Film Photoresist Adhesion
ABSTRACT –
Different cleaning processes on stainless steel
were tested to enhance dry film adhesion. It was
found that using an alkaline cleaner followed by
a well-balanced mixture of acids, acid salts and
activators provides an excellent surface for dry
film adhesion. Several Aquamer dry film resists
were compared on different types of stainless
steel (Type 301, 302, 304, 316, 321, 327, 410,
430, and 440). Adhesion and resolution were
used to make quantitative measurements to
characterize dry film performance. Comparative
data on a variety of Aquamer dry films versus
different stainless steels are included.
