Hello all,
I have a question about PCB test points. What is standard practice? Do test points get solder pasted. In other words should test points have solder on them? Or should the test points have no solder on them. Is it better for the test probe to hit a test point with solder or without solder. What are the pros and cons of doing it each way?
Thanks

Absolutely NO solder. Usually automated test equipment use a kind of pins called pogo pins (which are spring loaded pins) to probe test points.
With solder (and a bulged solder "pillow"), the tip of pogo pins may slip, breaking contact at best, short circuit and kill your board at worst.
