And once I've done that, and made a pcb, then there's the joy of attempting to solder the fecking thing down.
I think I picked the wrong part.Comment

For a diode, it's generally 2 pads.
For a transistor, it's 3 pads.
For an IC it's 8, 14, 16, 18, 20, 24 etc. pads.
For this surface mount abortion of a gsm modem it's 52 pads.
22 down one side, 8 along the top, and 22 down the other.
Just to make things worse, the leads on the component are mostly underneath, which will make soldering the POS a major trial.
Once it's blown up, I can order something easier to work with.Comment

At least, I used to know that.

Can you solder some little wires to the contacts? Or is that far too botch-cowboy for an academic institution?
Anyways, why are you doing the soldering and not the student?My all-time favourite Dilbert cartoon, this is: BTW, a Dumpster is a brand of skip, I think.Comment
