Reply to "Protection against voltage spikes"

That is pretty close to what I was doing with the exception of the vise. I'm using mounting putty or sometimes called blue tack, I think, but mine is white. Had it on the microscope base to hold the PCB. It works well at holding the PCB steady, doesn't move at all.

I did experience the part sitting up and not firmly against the PCB thing, Your tip helps here. I sorts did that, but it was a bit of a struggle as the component kept moving around when the solder heated up. I may have had too much solder on the first pad to start with? The 'technique' is still in the development stage! 

I have the Hakko 888D and I was using a Hakko T18-B tip. It is pretty small, but maybe a smaller one would be better? It did seem kind of large compared to the parts. I have a few others and may have one that is slightly smaller, I'll check my stash. Which tip do you use in your Hakko for the SMT stuff?

I was using the 0.020 - 63/37 solder, and it's good quality from Digikey. It's not the cheaper Asian stuff. I have heard most of that stuff doesn't do so well on through-hole or SMT. Watched some youtube vids of folks trying it out, they weren't too happy with it.

Got a couple of emails from OSHPark today, more PCBs are coming. One is the through hole version of the TVS tester and the other is an earlier version of it in SMT form from before you shrunk it down. I'll have even more to practice with soon, probably by the weekend.
