Step 9 of the PCM Process

The next step in the manufacture of Photochemical Machined parts is stripping off the protective coating of photo resist.

Many companies use machines that have a strip chamber on the etch machines.  This is practical when running a product line, less practical when producing the varied parts most Photo Etching companies offer.

What Is The Most Used Method
Of Stripping Used IN PCM?

The most common method of parts stripping is to soften and lift the resist coating using the “batch” method.

Other PCM
Stripping Methods

Other processes dissolve the protective coating completely.  In either process care must be taken to ensure no resist material is left on the parts and staining or surface corrosion does not occur.
