ST series

The ST SERIES of probe tips, available from GGB Industries, Inc., are precision crafted from a 0.020 inch (0.51mm) diameter solid tungsten shaft that is electrochemically sharpened to a specified point. These durable, 1.5 inch long solid tungsten shaft probe tips are for use in most standard micropositioners when probing an integrated circuit, pad, or line. A variety of radius point sizes from 0.5 microns to 10 microns are available to accommodate any probing need.

The ST Series tips are quite strong and can be used to scratch or punch through multiple layers of passivation while offering reliable probing at both an affordable price and the convenience of immediate delivery from our well-stocked facility. A nickel-plated option is also available allowing the user to solder to the shaft of the tip. When ordering the nickel-plated option, please add the suffix "NP" to the end of the part number. Custom sizes are available as well. Please contact our office if you would like to receive some samples.

T-4 series

T-4 tips are for use in most standard commercial micropositioners for probing integrated circuits, pads, or lines. Each T-4 tip uses the same 10, 22, 35, 60, or 125 micron diameter tungsten wire as our Model 12C Picoprobe, but is mounted to a 0.020 inch diameter, 2 inch long tinned copper shaft. 

An advantage of the 10 and 22 micron models pointed out by some of our users is that because the tungsten probing wire is thin and flexible it minimizes damage to the integrated circuit and allows them to probe the device for a much longer period of time. The flexibleT-4 tip remains in contact with the circuit even in the presence of probe table vibrations. 

T-4 tips are not recommended for use on sensitive nodes where capacitance loading could be a problem. Instead, one of our high impedance Picoprobes should be used. If you would like T-4 samples, please contact our office.
