Ask a Question

The 72BE Series probes are constructed from solid 20 mil disposable beryllium copper wire with a taper mechanically ground to the radius.
(Also known as 72BEG with optional gold plating)

Features
Low contact resistance copper material.
Soft material design reduces contact surface damage from tip.

Specifications
Reduced scrub marks on device pads.
Lower contact resistance probe.
Easily bent or cut to custom shapes.
Solderable surface for custom applications.

Note:
All prices are EACH PROBE, NOT PER BOX
Sold in boxes of  10, 20, or 25.

Made to order.



What size probe should I use?

The typical recommendation is to use a probe diameter that is half to two thirds the size of the contact. Remember, APT's probes are sold by the radius, so you must double the number to determine the diameter. It is normally found that a radius larger than 20 microns does not yield lower contact resistance. An example is: The contact pad is 10 microns, using the recommendation, you would then use a probe with a radius of 2.5 - 3.5 microns. (5- 7 micron diameter)

Why are some probes etch and others ground?

There are two common ways to manufacture the probe's taper and radius: 1.Electrochemically etch 2.Mechanically grind Why is one method chosen over another? 1.The base material is the driving reason: a. Tungsten, Tungsten rhenium are typically electrochemically etched b. Paliney® 7, beryllium copper, tungsten carbide, steel are generally mechanically ground materials This is the short answer, for more details on the subject please refer to the link in the Technical Resources Area under Probe Question's.
