Electronic – Is it normal/common to use this way of connecting point to point wire

protoboardsoldering

I want to make a circuit and am uncertain if the following is feasible/common and if there are better solution.

From the pin headers (the light blue circles), e.g. GndIn (upper yellow circle), I want to use 24AWG stranded wire to three other places on my protoboard (and one other), see the lower yellow circle.

Should I:

  1. Solder it like in the picture (one pin header with three wires soldered directly to the pin header); I can imagine it's a bit hard to solder three wires at the same time', maybe I should connect them first and solder them as one wire
  2. Make a vertical solder line until three pins below the GndIn pin header and solder each wire to a separate protoboard hole? However, this takes more space.
  3. Use another solution?

And I have actually the same questions for IC pins (not clearly shown in my example picture).

The protoboard I use is this type:

With so many unused holes, you can be more creative in routing jumper wires to holes and expand the number common pads. Use the adjacent row if necessary.

  • Just route then as neat as you can, like a PCB layout without clusters of overlapped wires to avoid signal crosstalk and so solder joints can be clearly inspected.
  • It doesn't take any longer and if the wires are tight and routed tight or bent in right angles, it will look better. Snake wiring looks a bit suspect to prospective clients or employers. Flush rectangular routing without overlap looks well planned.
  • Trained assemblers will use instant adhesive dots sparingly to prevent long loose wires. ( as long as you know it is permanent)
  • Don’t use excess solder.
  • Get the right solder temp to allow you to solder in 2~3 seconds by preheating and then add solder wire in a smooth sequence then release.
  • Magnet wire is popular for thinner appearance and I just burn thru the varnish without inhaling or use a fume extractor.
