Help me chose my pogo pin for THM Test Points on my PCB plz

(1/1)

Hello everyone,

I have a slight problem. I'm in an internship and don't know much about Pogo pins. I wish to select a type to come and touch the THM test point on the board that is given to me. The test points look like the ones in the linked picture. If anyone could help me, it would be really nice.

Have a nice day!
(Sorry for my poor English)

Pogo pins are not normally used with that style of test point.  You are generally better off probing without a through hole test point, onto a bare SMT pad or maybe an open through hole pad.
There are various head designs like the crown point that can help probe a non-flat surface.

That style of test point are not so commonly used these days, except in R&D.  You would normally use a hook type test clip with them, like seen in the photo at top right.

Are you planning to use pogo pins from above or below the PCB?
If you were probing from above, you might be able to use a large concave (inverted cone) head pogo, like a P25-A2 or P100-A2.
If probing from below, it would depend on how much the particular style of test points used protrude from the PCB surface.

Thank you, Kean. I will discuss all of this with my internship supervisor.
