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)
