suitable for the production of prototypes and small series. A proven method for the production of printed circuits, the transparent positive-pattern from the circuit diagram is accurately transferred onto the copper plates coated with POSITIV 20. After etching, the spraying of LÖTLACK SK10 is recommended to protect the circuits against oxidation. It acts as a highly effective flux during subsequent soldering.
K20-200 ml photo-positive resist
• the production of printed circuit boards using the positive method
• the lacquer resists strong acidic etching products
directions: clean and coat plates, dry lacquer and expose with UV light (340-420nm), develop in a diluted sodium hydroxide bath solution and etch copper with an iron-3-chloride solution, remove the remaining lacquer from the circuits with acetone, the PCB is ready. directions for use are enclosed in each aerosol can.
please observe shelf life (max. 1 year).
