A one-part concentrate (45% potassium carbonate) formulated to develop fully aqueous dry film photoresists and photoimageable solder masks. DX-45’s highly concentrated formula is ideally suited for use in feed and bleed systems, resulting in less frequent additions than with more dilute carbonate solutions. Proprietary ingredients enhance loading, help keep equipment clean, and ensure straighter sidewalls, cleaning the foot” of underdeveloped resist. These features result in greater productivity and less down time. “” one-part concentrate (45% potassium carbonate) formulated to develop fully aqueous dry film photore”

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.
