Dry Film Resist-Negative 5' x 12"

You can now create professional looking boards quickly and easily by using M.G. Chemicals’ Dry Film Resist (Negative). This negative film is a photosensitizing material that can easily be applied onto plain copper boards by using a standard laminator. Once applied, you are ready for exposing, developing, and etching.
4170-500ML Negative Developer required.

Features:

High resolution

Scum free at development

Excellent adhesion

Positive Resist:
With the Positive resist, everything exposed to the light will wash off during the developing process.
Negative Resist:
With the Negative resist, everything exposed to the light will remain during the developing process.
For that reason, the schematic printed onto the transparency for the negative process is reversed compared to that of the positive print out.

Specifications:

Unexposed color: Green

Exposed color: Blue

Nominal thickness: 1.5-2.0 Mil, 38-50µm
