Exposing - Step 6 of the PCM Process

During this step in the photo etching process, material with the photosensitive coating is exposed to UV light. This is a straightforward process that transfers the photo tool image onto the coated material.

Types of Imaging Used in Photo Chemical Etching

Imaging has been accomplished by exposing the coated material to sunlight; however in the northeast it is more practical to utilize more sophisticated equipment that will control the desired exposure length and intensity.

Types of Equipment Used in Photo Chemical Etching

Exposure equipment commonly used in the Photo Chemical Etching industry consists of a vacuum frame, high intensity UV light and multiple trays for more economical transfer of image. The coated material is sandwiched between the registered film tooling and exposed from both sides; this exposure polymerized the areas of the film tool.
