WAFER FLATNESS MEASUREMENTS
Valley Design will be exhibiting at Photonics West in San Francisco, January 31 - February 2, 2017, and at LASER World of Photonics in Munich, Germany, June 26 - 29. For all the details on these shows, please click here.
We will be displaying a wide variety of product samples including:
We look forward to meeting with you to discuss your specific project requirements, whether it is for precision lapping, polishing, dicing, CNC machining, grinding, hole drilling, or for standard or custom wafers, substrates, shims, spacers or other flat components.
- Plates as large as 48" square or larger - lapping and polishing
- Tiny chips -0.127mm square - dicing
- Parts as thin as 10um thick - lapping and polishing
- Flatness to 1/10 wave (1/5 Helium Lightband)
- Parallelism within 0.000040" (1 micron)
- Thickness tolerance to +/- 0.000020" (0.5 micro meters)
- Surface finish - our best standard optical polish is < 10/5 scratch/dig (7 Angstroms Ra)
- Superpolishing to < 3A on some materials also available
