Test SMD J201

[TravisM]

I just completed my first surface mount soldering and I'm interested if anyone knows of a way to test them before I finish populating the board. I'd like to know if my solder joints are good before it gets too cluttered to fix them. I'm building the golden falk overdrive.

You can check continuity between the pins of the transistors and the adjacent component according to the schematic.

One thing I recommend for future builds is to use PCB adapters for the SMD’s. Pretty cheap but allows you to test your SMD before putting them on your build.

PedalPCB also sells them and they're less expensive than Tayda as well:

Continuity checked out, thanks. I was thinking a bit too deep, I was considering trying to use the through hole pads to send a voltage through them and check them that way. I've already have some of those adapters, but didn't even think about using them since the pads were on the board already.
