A one-part concentrate (47% potassium carbonate) formulated to develop fully aqueous dry film photoresists. ADC 47 is economical to use and easy to handle, eliminating the need to weigh and dissolve powdered materials. ADC 47 also works well for developing aqueous photoimageable solder masks or for any other situation where carbonate is used.
A room temperature, conventional speed, electroless copper process which will deposit a dense, adherent copper film on catalyzed surfaces for the production of printed circuit boards. CIRCUTEK EC-1050 is easy to control, and has a broad range of operating temperature and bath loading tolerance. The copper produced is a bright pink, fine-grained deposit which is readily receptive to subsequent copper electrodeposition.
A mildly activated flux for use prior to hot oil fusing. 291 FLUX is formulated without isopropyl alcohol, making it safer to use and store. It is compatible with THERMO FLO® and PRO FUSE Fusing / Leveling fluids. 291 FLUX contains ingredients used in the fusing fluids, which results in reduced consumption and prolongs the life of the fusing fluids.
