I've built myself a jig for faster assembly of #throughhole components. This #PCB has quite a few of them with different heights and it's pretty annoying to assemble them without help. So I designed this thing. Let's see if it even survives the soldering iron.
I'm looking to design a PCB that'll be carrying 40A peak (probably closer to 30A continuous) at 36V for my hauler project. Does anyone have any good guides on high current PCB design? Thinking in terms of recommendations on via stitching etc between polygons.
Realistically all the board will be doing is current monitoring with a couple of TI parts and a micro on a CAN bus, holding a fat relay as the battery cutoff, fuses and some connectors for power distribution.
Continued thread
Many cool answers, but the most interesting question still remains.
This board looks like it was covered in rosin deliberately, as a protective layer.
I failed to find any guides about it. Anyone with hints?
Solder warriors, how do you protect your etched boards from corrosion?
I bought this one a lifetime ago. Clearly homemade. It's covered with rosin.
I thought rosin was corrosive to the traces.
What technique is this? What kind of rosin is used here?

My first #SAO, first #PCB commission (for #HacksterIO), & first PCB designed with Autodesk Fusion – a simple little light-up board that can also work as a hanging pendant, earring, keychain, etc. :3
Limited-edition (test run w/ dark blue) for #DefCon33 – come grab one if you're still here!
