How to use Positive Photo Resist (PC 197)


PC 197 Photo Resist can be used to coat any type of PC Board material, as well as exotic materials such as Glass, Aluminum, Silver, Gold, and more. Useful for preparing boards for in-house manufacturing or prototyping, enabling you to have complete control. PC197 may be dip coated, spin coated, spray coated, or brushed ( under yellow or red light conditions ). Sensitive from 340 to 420 nanometers. Results have been achieved at less than 10 mils per line width. Available in bulk quantities from 2 ounces up to one gallon sizes.

PC 197 is also available precoated on a large selection of Copper Clad Boards of various thicknesses and substrates, both one sided and two sided, up to 18" X 18".

PC 197 POSITIVE PHOTO RESIST is used to coat materials in order to make them photosensitive. Materials should be cleaned from all dust, dirt and oils. The materials should never be handled without gloves as the oils from the skin will cause contamination and the Resist will not adhere properly.



1. Materials may be dip coated, spin coated or sprayed under yellow or red light conditions.

2. Materials should be air-dried until no longer tacky and then allowed to cure in a light proof environment overnight to allow solvents to evaporate.

3. A convection air-oven may be used to force dry the materials at 125 F for 15 minutes. This will allow the solvents to be drawn off. Improper drying will cause lack of adhesion.

4. Exposed Resist is sensitive from 340 to 420 nanometers. An INJECTORALL PC557F or PC557 may be used to expose the resist for 3 to 8 minutes depending on the light source and distance.

5. Develop for 2 minutes with D3 developer. Developer should be between 72-75 F.

6. Resist may be thinned or cleaned with PC197th thinner.

7. Warranty: This product is warranted free only from manufacturing defects, and only to the extent of replacing of chemicals so defective.
