Dense switching matrices
Reed relays can route many instrument channels in a compact load-board, probe-card or switching-matrix architecture.
Application: Semiconductor ATE
Reed Relays for Semiconductor ATE and ICT Test Equipment
Semiconductor test systems need dense, repeatable switching with low leakage, stable contact behavior and controlled parasitics for wafer sort, package test, ICT and device characterization.

What this component is used for
Measurement repeatability
Low leakage, high insulation resistance and stable contact behavior help protect small-current and high-impedance measurements.
Fast serviceable design
Modular relay banks simplify fixture maintenance and support multiple DUT families.
Application details
Wafer sort and parametric test
Route SMU, DMM, LCR or high-voltage stress channels to selected pins while guarding sensitive nodes.
ICT and functional test
Switch test nodes, boundary conditions and stimulus lines in production fixtures.
Burn-in and reliability fixtures
Support controlled channel selection for stress, monitoring and validation equipment.
Device characterization
Use relay matrices to compare devices, isolate channels and automate repetitive measurements.
Selection factors engineers should confirm
- Leakage current and insulation resistance under humidity and contamination.
- Thermal EMF and contact resistance for low-level measurements.
- Capacitance and bandwidth when switching RF or fast digital signals.
- Coil drive, magnetic interaction and relay density on the board.
- Expected operations, hot-switching conditions and maintenance strategy.
Engineering note: For ATE pages, exact relay ratings should remain tied to specific product datasheets; the application page should explain selection logic rather than overclaim universal performance.
