Product description
Kontakt Chemie POSITIV 20 200 ml. POSITIV 20 is a photo-positive resist lacquer in aerosol form, intended for the production of printed circuit boards and other photolithographic applications. It enables precise transfer of patterns from transparent originals to copper laminate. The applied film is sensitive to UV light in the wavelength range 370–440 nm.
Instructions for use:
- Surface preparation: Clean the copper surface thoroughly from grease and oxides. Use isopropanol.
- Application: Spray POSITIV 20 from a distance of 20–30 cm in an even, zigzag pattern. Keep the can as vertical as possible to achieve an even coating.
- Drying: Dry the coated surface in darkness. Gradually raise the temperature to 70 °C over 10 minutes and maintain this temperature for an additional 15 minutes.
- Exposure: Place the transparent original onto the coated laminate and expose with UV light (370–440 nm). Exposure time depends on the light source and thickness of the coating.
- Developing: Develop with photoresist developer (41000469), in a solution of 20 g per two litres of water at 20–25 °C for 30–60 seconds. Stir gently and then rinse with water.
- Etching: Etch with sodium persulfate (41018866).
- Resist removal: Remove remaining resist with acetone.
Warning:
Contains: 1-methoxy-2-propanol; monopropylene glycol methyl ether, 2-methoxy-1-methylethyl acetate, acetone; propan-2-one; propanone
