 		 #169915 - That's worth a whole thread in itself - and a FAQ
Responding to: ???'s previous message
Per Westermark said:
At least for prototypes, people will do well to add zero-ohm resistance bridges to all important signals, to allow easy access to them and, if needed, allow patching.

Not just for BGAs - that's a really great idea for any prototype!

Also things like adding testpoints where wires can easily be attached for monitoring/debug.

Might be worth starting a separate thread for "favourite (hardware) debug tips"...
