These UNUSED sheets are left over from a project. Wrapped and stored in a cool, dark place in the original cardboard box. These boards come with a photo-sensitized etch-resist coating. Trace layout contact negatives and a high wattage (300 watt) floodlight expose the coating, the unexposed resist is washed off, and then the boards are etched in the normal way. I cannot guarantee that the photo-sensitized coating still works. If it doesn’t, the resist can be washed off and the boards etched with resist tape or left on as a corrosion resistant coating. I no longer have the chemicals to do this.

Type: Kepro photo-sensitized circuit boards, 2 – sided 2 ounce (thicker) copper, fiberglass substrate.

Kepro part number: S22-1224G
