Circuposit™ Desmear
Circuposit™ desmear process results from DuPont long expertise in a solvent swell product designed to enhance the resin texturing and smear removal of high Tg materials in the subsequent Circuposit™ Promoter stage. This process defines a new standard for via plating. The serie contains products formulated to process both traditional FR-4 type laminates and more advanced high Tg materials.
