Hi,
I have this board, that has smd on the bottom side (the first time i see this here). Now 6 nodes are inaccessible unless i probe on smd pads (resistors). Is this a good idea, who has done this?.
Regards,
Andre

Probing on components is a risky practice. The only way to probe SMT parts directly is to probe on the solder fillet. This presents (3) main problems:
1. Solder fillets are not flat, causing the probes to side-load, which will quickly make them unusable.
2. SMT parts often “move” from UUT to UUT making consistent contact a problem.
3. Probing directly on components can damage the component and also can render a poorly soldered component “good” by forcing down a lifted pad.
Who has ignored this ??, tell me your experience
