Custom Precision Spacers and Shims

APD provides ready-to-use custom chips that can be used as shims, spacers, and coupons for prototyping and testing.These shims can also be laser marked with serial numbers, part numbers or bar codes. Because these parts are turnkey we save you time, money and hassle.

What we make according to your specifications:

  • We create rectangular die pieces made of non-metallic materials (think silicon, glass, sapphire, etc.) with very precise X, Y and Z dimensions. The measurements of these custom precision spacers and shims are specified by you to fit your application. Optionally, you can also specify custom coatings or special laser markings for identification.

The current DIY (do it yourself) approach:

  • Find a wafer house and buy the wafer

  • Backgrind the wafer to the desired thickness

  • Polish the wafer (if required)

  • Add the oxide layer (or whatever type of layer required)

  • Find a dicing house and get the wafer diced

  • Add the serial number (if required)

  • Package the coupons in either a waffle pack, gel-paks, or tape and ring

The better way.
