Chemical etching is a low-cost alternative to stamping tools utilized for prototyping and low-volume production.
| Composidie Inc. can support your production requirements with our Leading Technologies, Inc.
etching facility. |
| ▪ High Speed, Continuous Process |
| ▪ Non-Contact Glass Mask |
| ▪ 0.002" to 0.025" Thick Materials |
| ▪ Dry Film Type Photoresist |
▪ Automated vision alignment system
for
exposure assures
+/- 0.0005"
(0.0127mm) offset mismatch |
▪ Accurate unit-to-unit progression
tolerance of +/- 0.001" (0.025mm) |
| ▪ Leadframe, Connector, RF/EMI Products |
▪ Major benefit in prototyping designs
due to inexpensive tooling costs and
shorter lead times. |
