Re: MiniPCB2 bunches of weirdness
Your SHC may be working for now (ignoring the connection to the controller for now as that may be a software issue) but it looks like issues will be likely to develop down the road due to soldering problems.toggle quoted messageShow quoted text
I see a lot of pads that do not have sufficient solder (e.g. voids) and that probably means cold solder joints which could let go at any time. I would touch up all the joints with a 300 degree C iron and a bit more solder. Hold the iron on the joint for at least a second and a half after you remove the solder wire to make sure you get good flow. The SHC in particular has some tricky spots to get right because the ground plane is a complete copper layer (the top layer) and as such acts as a prodigious heat sink... it requires more time to reach proper temperature than the non-ground pads. All the PCBs actually have the same issue, they all use a copper pour for the ground plane. There are lots of examples of what good (and bad) solder joints look like on the web.
If the soldering on the controller looks the same, I would go over that as well.
