ETAP240 Photoimageable Acid/Alkali Etch & Plate Resist

Description:

ETAP240 is a contact exposure, negative working photoimageable etch and plate resist, formulated for use as a cost effective alternative to dry film-resist in the manufacture of high density multi-layer PCBs.

It can be applied by air-spray or screen-printing and is suitable for use with alkali and acid etchant solutions and plating solutions. After etching or plating it is easily removed in a sodium hydroxide solution or proprietary resist strippers.

• <25µm (1 mil) resolution capability. • Excellent adhesion and conformance to copper surfaces. • High acid & alkali etch resistance. • Screen print, spray, dip or roller-coat.
