Can be used with 74CJ and DCP-15X Series probe holders to provide a ground return path when used with another coaxial probe.
Does not require the purchase of additional DC holder if you already own APT's 74CJ probe holder products.
The standard probe length is 1.2" with a 60 degree bend. A shorter 1 inch length is available should you require a lower profile probe, and different bend angles are also available upon request.
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.
