High-Speed Spring Contact Probes

High-speed spring contact probes are designed for wireless functional test fixture on high speed transmission. Those probes can bring a socketless solution for customers, that reduces the loss and resistance compared to the tranditional spring contact probes. High speed spring contact probes provde a varity of test grids from 0.45mm( 0.0177'') to 2.54mm( 0.100'') and selectable tips for different test components.

Advantages:

1. Smaller Pitches Than Standard Probes.

2. Socketless Fixture Application.

3. Lower Insertion Loss And Resistance.

4. Reducing The Materials of Fixture Boards and Saving Cost.

5. Stable Signals Transmission.

6. A Varity of Pitches Probes in the Same Fixture.

7.High Precision Spring Contacts.

Barrel-Ring Spring Contact Probes

Barrel-Ring Spring Contact Probes are designed for wireless contact fixture, they are a part of high speed test probes.

This spring probe is a kind of double-ended contact probe with a ring on the upper part of tube.

The Barrel-Ring Spring Contact Probes bring you

1. Saving time on the probes replacement, 

2. Effectively shortens test length and reduces test grid pitches

3. Smaller test products 

4. effectively improves test performance.

5. Board drilling size will be reduced
