SGB Tooling, LLC Provides Essential Services to the Semiconductor Industry.

IC (Integrated Circuit) Chips that provide the computing power for modern electronics may take a year or more of testing and development before production becomes viable. That’s where SGB Tooling’s specialty service supports IC chip manufacturing.

With 28 years of design engineering experience, Sam Glazebrook founded his company in January of 2018 to provide the test fixtures used by US semiconductor manufacturers. Sam designs all the components for the test fixtures, assembles and ships the fixtures to his customers.

SGB Tooling fixtures enable you to place a single chip inside the fixture pocket without creating a permanent electrical connection for ease of repetitive testing. Hundreds of test points make contact with spring-loaded pins in an extremely tight array.

Since each tooling fixture design is unique, Burger & Brown Engineering, Inc. makes the parts for SGB Tooling, often in small lots of 1 to 3 pieces each. Inspection and cleaning of the test fixture components are often done under a microscope. Hole diameters are frequently 0.003” requiring production using specialized high-speed milling machines with extremely accurate and repeatable tool positioning.

A variety of materials are used for these high-tech fixtures including specialty plastics and ceramics that are subject to extreme temperatures during IC Chip testing and production.
