Bare PCB Test Probes
Drawing on more than two decades of experience in bare board electrical test, ECT offers the world's largest selection of off-the-shelf and custom probes for this application. These products have been proven in years of high-volume production, and have been continuously refined to provide the best possible performance with today's smaller feature sizes. The proven performance of these probes continues to set the industry standard for performance, reliability and value.

Technical Notes
Replaceable probes for dedicated test fixturing for Bare PCBs such as Everett Charles Technologies' series 32 Fixtures:

Figures 1 and 2 show how probes designed for varying test center dimensions can be "mixed" in the same test fixture without costly machining of the probe plate. Probes designed for 0.050 or 0.100 inch travel and 0.050, 0.075, and 0.100 inch test centers can be mixed for bare board testing.
