RoHS Compliant Dry Film Resist – Negative
416DFR

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.
*Negative Developer required

General Features:

  • High resolution
  • Scum free at development
  • Excellent adhesion

difference between positive and negative presensitized boards?

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. (See diagram above)
