I have a PCB where I have several point to point wire connections. I am using 18 AWG (<1.0237 mm) stranded wire which just barely goes through the 1 mm holes in the PCB. Note that I have multi-amp power (e.g., 7.5 A) flowing through these wires, so I need to stay "thick".
The problem is that I want to solder the wire on both sides of the PCB, so what I am doing is removing enough insulation to expose the tinned copper of the wire above and below the PCB and soldering to that. Unfortunately, this fries some of the insulation that is near the solder point where the wire enters the PCB, due to proximity with the soldered joint.
Also, the PCB hole spacing is 2.54 mm (this is one of those project PCBs that just has a rectangular array of circular solder pads on both sides and you connect them with wires or solder bridges). This means that if I have wires in adjoining holes, there is very little clearance and the possibility of a short from the wire exposed at the melted insulation points.
There must be a better way to do this - perhaps some sort of a pin or something that can easily go through one of the holes in the PCB and be solderable on both sides (one side to the wire which wraps or plugs into a cap or crimp connector and the other side would just be a pin that produces from the bottom of the PCB that I can solder to). I think they used something like this way back when for point to point wiring on PCBs, but I can't find anything like that these days - or maybe I don't know what to search for.
If you have any experience in this, please help.
