The process

What is photo etching?

Photo etching, also known as chemical etching or metal etching, is a highly precise, tightly controlled corrosion process used to produce complex metal components with very fine detail.

When component integrity is critical, photo etching is often the only suitable metal machining technology as metal temper and magnetic properties are unaffected.

What is photo chemical etching?

How does it work?

The etching process can be demonstrated in nine steps. Precision Micro has advanced these principles, investing in new technologies and developing proprietary methods which have set the standard for accuracy and repeatability.
