Standard/Sizes
ST Seires Hard needle
Specification:ST
Size:Hard needle tungsten material
Features:ST series hard needles are made from 0.020 inch (0.51mm) diameter tungsten needles after electrochemically processing and they come with a length of 1.5inch (38.1mm).They are mostly used for the vast majority of chip electrode spot tests and circuit spot tests.ST series hard needles can be used to scrape or pierce the passive layer on the chip surface.They can be optionally plated with nickel on the surface. If you choose nickel plating, add "NP" after the model number.
Kelvin Probe
Specification:Test frequency 150MHz
leakage<10fA
capacitance<10fF
Size:Regular
Features:Suitable for small signal testing. APT Kelvin Probe is suitable for four-wire method testing to reduce the impact of wire resistance and contact resistance on testing and ensure the accuracy of testing of small resistances. In addition, APT Kelvin Probe also can be used for high-frequency(such as 150Mhz) tests.
Large Current Shunt Probe
Specification:DC capability of a single shunt pin is 5A, pulse test capability of a single shunt pin is 50A
Size:number of needles can be customized
Features:Suitable for high current Testing and can better contact the sample
T-4 Series Soft Needle
Specification:T-4
Size:soft needle
Features:T-4 series soft needles are mostly used for spot testing circuits and electrodes of integrated circuits, or mini electrodes made by FIB (focused ion beam). T-4 series soft needles are made of tungsten needles with different diameters which are welded to tin-plated copper needle bars. Among them, T-4-10 and T-4-22 show remarkable advantages over other models according to customer feedback, because their needle diameters are thin and have good bending elasticity, which can greatly reduce the damage to the chip electrode and ensure perfect contact with the electrode even under vibrating environment. T-4 soft pins are not recommended to be used in sensitive nodes because they will cause capacitive load problems and the high-impedance Picoprobes series are more adviseable to be used instead in such situation.
