Utilizing programmable DISCO and K&S saws, parts can be diced to micron level tolerances with 200X optical magnification. Valley has recently expanded its dicing department, and now offers one of the largest production dicing capacities in the industry. Parts can be diced as small as 0.127mm square. Valley dices both customer supplied wafers and parts, as well as dices parts from our extensive material inventory. Materials diced include Fused Silica, Aluminum Nitride, 96% – 99.8% Alumina, Glass of all types, Silicon, Sapphire, Silicon Carbide, Macor ceramics, Ferrites, Germanium, Polyimides and PEEK, metals and more.
High volume dicing features and applications include:
- Chip-free edges
- Beveling
- Scribing
- Trenching
- Die edge polishing
- Wide or narrow streets from as thin as 25um up to 1.25mm
- Thin die dicing
- Die edge trimming
- Double cuts
- Stepped cuts
- Thick wafer dicing
- Plunge cuts
- Coated and patterned wafer dicing
- Metallized substrates and wafers
- Nitto and UV tape dicing
- Wax bonded dicing
- Top side wafer protection
- Shims, spacers and submounts which can be sequentially spaced within microns
In addition to dicing services, Valley offers a true one-stop shop including CNC 4 axis micromachining Lapping and Polishing services, Ultrasonic Hole Drilling , backgrinding and other precision machining services for custom and standard parts from as small as 0.127mm square to 450mm diameter wafers. Valley has even processed parts as large as 72” long.
