In-Circuit Test Fixtures – ICT

High-precision, custom-engineered “Bed-of-Nails” ICT test fixtures designed to hold populated PCBs securely and accurately detect manufacturing defects.

In Circuit Test Fixtures 01

Understanding ICT Test Fixtures

In-Circuit Test (ICT) fixtures are custom-built tools designed to keep populated circuit boards steady during testing. By using a specialized “bed-of-nails” probe setup, these fixtures make direct contact with your board to catch assembly issues—like short circuits, open paths, or misplaced components—early in the production process.

To make sure every test is accurate and reliable, Fixtronic builds these fixtures using high-precision G10/FR4 epoxy glass plates and ultra-fast drilling technology (up to 200,000 RPM). This allows for exceptional alignment accuracy down to 0.005 mm between the probe plate and the moving alignment plate, so even tiny test points align perfectly every time.

Key features & platform support include:

Extreme Precision
Turnkey Customization
Broad Tester Compatibility

Center-to-center drilling accuracy of 5 microns for flawless pin alignment

Complete finishing, high-speed drilling, and custom tooling tailored to your board layout.

Designed to seamlessly integrate with major ICT platforms, including Keysight, Teradyne, Digitaltest, SPEA, TRI, and Seica.
