STSeries DC needle tip

GGBCan provide curvature radius0.5-10umThe DC tungsten needle tip is wear-resistant. It also offers nickel plating options, allowing users to weld onto the pointed shaft. When ordering nickel plating options, please add a suffix at the end of the part number“NP”. We also offer customized sizes.

T-4Series DC Soft Needle

T-4Series and12CSimilar to the series of needles, with the same diameter10，22，35，60，125um Tungsten detection lines are thin and flexible, minimizing damage to integrated circuits and allowing them to detect devices for longer periods of time. Even in the presence of probe table vibration,T-4The tip is still in contact with the circuit. Not recommended for use on sensitive nodes where there may be issues with capacitive loadsT-4Tips. Instead, we should use a high impedance micro probe.
