A one-part concentrate (40% potassium carbonate) formulated to develop fully aqueous Riston® photopolymer films. D-4000 is economical to use and easy to handle, eliminating the need to weigh and dissolve powdered materials. It is formulated to give optimum results with DuPont™ Riston® films and FoamFREE™ defoamers in conveyorized spray developer equipment.
ResiStrip 5000 is designed to strip difficult to remove photoresists and LDI films quickly, thoroughly and economically. The stripped board is oxidation-free and ready for oxide or etching.
PreLam Cleaner is a cleaner/microetch/adhesion promoter for use on copper and other metals. It will give optimal resist adhesion both initially and during subsequent processing, where other chemicals can weaken the bond at the copper/photoresist interface. PreLam Cleaner S yields a non-traditional looking panel with a bright orange color rather than a more typical matte pink.
