Cleaning
Step 4 of the PCM Process

Proper metal preparation, degreasing, and the removal of surface contaminants is essential for proper adhesion between the raw material and the photo resist during the coating process.

Modern PCM companies have invested in “clean lines” for improved material cleanliness.  These conveyorized machines are typically multi-chambered and material is put through a series of clean and rinses to ensure proper surface condition. 

The quality and quantity of the finished parts depends greatly on the care taken during this step.
