Fixture probe selection standard.

Fixture probe selection standard.

It is recommended to use INGUN original probes, corresponding to different measuring pin types, and choose the appropriate needle type. The test proves that INGUN original probes have the advantages of small contact resistance, excellent elasticity, and long life. Currently, high imitation probes also have the same laser marking and weight, so the simple way to identify it is: press the probe vertically with the fingernail, and the elastic and smooth ones are genuine INGUN products. When making fixtures, it is necessary to pay attention to the need to meet 2/3 of the downward pressure movement of the probe. Less than 2/3 will cause unstable contact impedance of the probe and affect the stability of the test.
