Hi all,
I'm interested in learning more about what "good practice" is for protecting circuits on PCBs. In particular I am interested in:
-Fusing on PCB
-ESD protection
-Reverse Polarity protection
-Power circuitry protection (MOVs, etc.)
EDIT: -Is every PCB input/output protected individually? Or just the power input?
I bet most people don't consider this for hobby boards (I sure haven't), but I am sure it is present in commercial products.
As a related question... I think of PCBs in a commercial environment as a throw away element. I doubt many companies will rework failed boards returned by customers. What good does adding a SMD PCB fuse do? If it blows, the whole board/product is dead and thrown away anyways.
Thanks so much, not finding much literature on best practices when searching line.
