Engineering Design Guide For Photo Chemical Machining

Photo chemical machining, or photo etching, is a fabrication process used in the creation of precision metal parts. Often, it is used as an alternative to conventional processes like stamping, punching, wire EDM, laser cutting and other common machining methods. Currently, photo chemically machined parts are used in a variety of industries, ranging from microelectronics to medical devices and RF & Microwave.

In this guide, you will learn:

  • The impact of metal sheet size and thickness on costs
  • How the sheet size/thickness affects tolerance
  • How to compensate for etch factors for tool design
  • Tab configuration vs. standard tabbing vs. recess tabbing
  • Outside and inside corner radius requirements
  • The uses of half-etching
  • Different ratio etch capabilities
