Model W2.5 x L6.5 Mini Probe Station
Price $1,850.00 USD

This portable manual probing station is designed for a versatile, comfortable, and accurate operation on up to 2.5” wafers or 2.5” X 6.5” printed circuit board assemblies.

This turn-key, manually operated probing station, model W2.5 x L6.5, is part of the D-COAX commitment to the test and measurement and fabrication industries. This affordable machine offers a versatile design with portability in mind. This is the first probing station to offer such a light weight and portable design; put it in the custom transport case (sold separately) or your back-pack and take it where you need to make your measurements, in another laboratory or office. Unlike the competitor's probe station, you can sit or stand while using this unit due to the very low table to chuck height. The chuck has a unique in the design, with a width of 2.5 inches and the length of 6.5 inches, suitable for circuit boards or multiple devices. The Z positioning is via a digital readout in micrometers or inches for accurate probe “touch-downs”. Its versatility, affordability, and user friendly features make it the best manual probe station on the market.

Price $350.00 USD
probe transport case

Two probes oriented to face each other isn’t always enough selection because some circuits have pads at 90 degrees to the other probe. The adapter can be used to place the probe 90 degree from the original position or hold two probes oriented at 90 degrees to each other.  The pitch between two probes can be adjusted by sliding the probe holders inside the 0.6 inch slots in the adapter. Use another adapter on the opposite side for wider pitch.This probe station adapter is compatible to any D-COAX probe station.
