An aqueous photoresist stripper specifically formulated for flexible circuit stripping operations. FLEXSTRIPcontains copper antitarnish agents providing a cleaner surface for subsequent flex material processing. FLEXSTRIPproduces fast strip speeds while producing large particles suitable for filtration. It contains no glycol ether solvents for greater compatibility with flex materials and a safer working environment.
A one-part concentrate (40% potassium carbonate) formulated to develop fully aqueous dry film photoresists. DX-40 is economical to use and easy to handle, eliminating the need to weigh and dissolve powdered materials. It contains a unique blend of ingredients to enhance the loading capacity of the solution and help keep the equipment clean. These special ingredients help ensure straight sidewalls and will help clean the foot” of underdeveloped polymer. These features result in greater productivity and less down time. DX-40 also works well for developing aqueous photoimageable solder masks or for any other situation where carbonate is used. “” one-part concentrate (40% potassium carbonate) formulated to develop fully aqueous dry film photoresists.
