What is a PCB Test Point?
Very simply, a PCB #test #point is an electrical pad or via that can be probed during an ICT. These points are used to monitor voltage, current, and/or signal behavior in specific circuits. They can also be used to inject signals into a circuit. A pad on an existing component or a specific via in an existing layout can be assigned as a test point. The other option is to create custom test points in your #schemati and import them into your layout. This is a good idea if you suspect a component pad will not be accessible with a probe after assembly, or if you want to keep track of your test points directly in your schematic.
Typical pad or via #test #points are not ideal for all circuits and devices, as they might distort signal behavior at extremely high edge rates and frequencies. If you place a custom pad as a test point, it takes up a small amount of space in the layout. However, they are still useful for a variety of measurements. If you are working in the very high speed/high-frequency realm and you need to gather accurate signal behavior measurements on interconnects, you should use some validation structures on a prototype board or test coupon.

Thanks, it was a big help!
Welcome mike :)
When I want to rotate the 3D model, I get a message that says 3D not available, what could it be? thank you.
Hello Cristian,
1) Make sure under "View Configuration Panel" you have enabled (ON) "Show 3D Bodies" in "view options menu" ( "View Configuration Panel" is available at the right corner of Altium Designer under "Panels") or you can also enable "Show 3D Bodies" by Pressing "Shift+Z".
2) In case the first solution is not working then make sure that you have not "Hidden" your 3D model in the PCB panel. Please see in this video from 6:40 to 7:50 min ( th-cam.com/video/gkYHvQd6KAU/w-d-xo.html ) how to enable the 3D step model in the PCB panel.
I hope the first solution will work in case not , please feel free to write me.
Great Video.Thx
Thanks 👍, if you like the contents please subscribe my channel, I appreciate :)
