Sierracin to Discontinue Semiconductor Tooling

Sierracin, a Sylmar-based aerospace and electronics concern, is moving out of the semiconductor tooling business.

The company said it sold its Irvine semiconductor tooling operation to Master Images of San Jose for an undisclosed price. Master Images also has acquired an option to buy Sierracin’s Milpitas plant for semiconductor tooling.

Sierracin said the business isn’t in keeping with its long-range plans and that it will sell the Milpitas plant whether Master Images buys it or not.
