A Short Explanation of the Photo Chemical Etching Process

1. You send your print to us and your drawing is electronically manipulated and sent to a photo plotter, creating the photo tool (film) for your part
   
2. Metal is cut into sheets, scrubbed, coated with light sensitive polymer (resist) and your film exposed on it.
   
3. The sheet is developed, removing resist around your parts.
   
4. The sheet is run through a conveyerized etching machine which dissolves the metal not covered with resist.
   
5. Your parts, now etched to your specifications are put in an alkaline stipping bath to remove remaining resist.
   
6. Parts are dried and sent to QC for inspection, further work (plating, forming, etc.) and packaging.
