Lapping
Valley offers precision lapping of all materials and has developed a proprietary
process to achieve minimal material stresses and highest yields. Depending upon
the material, Valley has the capability to achieve flatnesses to ¼ lightband
and parallelism to .000050", and specializes in very tight tolerances.
We lap all materials including Glass, Quartz, Ceramics, Metals, Silicon and
many others. Valley processes parts as small as a few thousandths of an inch
and up to 32" and larger in diameter. Valley also has extensive experience
with thinning circuited and bonded wafers to as thin as 50 microns. For a complete

AF45, BK7, B270, D263, LASFN9, 1737, 7070, Ceramics, Lithium Niobate, Borosilicates,
Soda Lime, Crystals, Silicon and Metals. In
stock materials include Fused Silica, 99.6% Alumina, R-plane Sapphire,
Aluminum Nitride and Float Zone Silicon.
Valley Design provides custom parts,
as well as in-stock
items. We process prototype orders, as well as full production runs, and currently
process over 1,000 parts daily for our customers worldwide. With facilities
on both East and West Coasts, we operate three shifts, and are ready to serve
