1.Micro Series Probes
The center distance between the two test points is generally 0.25mm to 0.76mm.
2.Switch Probes
Switching probes have a single probe with two currents.
3.Coaxial Probes
Used to test high frequency signals, with shielded ring can test within 10GHz and 500MHz without shielding ring.
4.Rotator Probes
The elasticity is generally not high, because its penetration is inherently strong, generally used for OSP-treated PCBA testing.
