  • PS For future reference, does this sort of exposed PCB trace (pad?) used for electrical connection take solder well?

    I can’t tell if you have gold plate or just raw copper (probably gold. But in either case, yes, it is solderable. You can think a little bit about how they manufacture the boards. First the print on the green solder resist, then they dunk it into an electroplating bath for a gold finish, or a dunk it in solder for HASL. It would be a lot of trouble to go through (=$$$) to individually mask off that part of the board for some special process.



  • Unless you’ve managed to get a switch made out of superconducting material and you’re working inside a liquid helium bath, everything has resistance :)

    You’ll have a bad time trying to measure such low resistances, so usually you can look at the datasheet for the switch you’re using or for a similar switch if you need a ballpark number. You’ll see an on-resistance, and a max current (since there will be arcing when you open the switch).

    If you do want to measure the low resistance, you’ll need dedicated meter with a kelvin connection.



  • that’s a good question–I’ve always just gotten the concave chisel tip because they’re the same price and I didn’t see any drawbacks to it under any circumstances.

    I do tend to do a lot of work like this with K-tips, and those don’t have a cup. I imagine that the non-concave tip would work ok. I would give it a try with your current equipment, and then think about getting a new tip if you end up doing this more.

    You’re kinda right? It’ll be harder for links to be considered authoritative by google since they’ll be across a bunch of smaller websites with fewer references to them (unlike reddit, which is 1 website with billions of links to it).

    But maybe it’ll work somewhat anyway since every page has “Join Lemmy” text in the bottom & google might be able to link them together.

    On the other hand I have no idea and I’m just going off my vague understanding of how the google algorith m works.
