Superior Soldermask, Dry Film, and Liquid Photomask Adhesion.


MultiPrep 200 is a revolutionary pretreatment process for the adhesion of solder mask, dry film and liquid photoresists to copper surfaces. Leveraging decades of etching experience, MultiPrep 200 is engineered to meet today's challenging adhesion requirements. It completely eliminates pumice and brush scrubbing for improved process efficiencies and product uniformity during the fabrication process.

MultiPrep 200 delivers an optimized, micro-roughened,  copper surface topography to provide uniformity of etched pulse-plated panels. It is a universal process that is ideal for solder mask pretreatment prior to final finishes such as ENIG, Immersion Tin, OSP, HASL through assembly. The micro-roughened topography enables solder mask to "stick and grip" to the copper surface with exceptional reliability and durability. 

Use MultiPrep 200 in any PCB operation requiring unparalleled 
copper adhesion to organic films.
