I'm testing a flying loom using a DSUB-9 serial cable:
try to
- push the wires into the pad (cut the extra part on the other side, if necessary)
- use the right temperature and time when soldering (so insulation is not melt, but soldering is fine)
- ask for someone's help. It takes much more time to do it nicely alone
- make sure no hair is tangling - that will short sooner or later
- use hotmelt after testing, to prevent damage
- also cut short and insulate the hair from the cable shield
Answer to feedback
- It looks a lot worse than it really is, I have tested it and there are no loose strands anywhere (tinned the wires before inserting).
- Because I had no help I intentionally cut of a lot of insulation because access was easier from the top, there was a lot of wire protruding through the board that I cut off after soldering.
- I will use the correct solder next time, mine required almost 400C (but works great with K-type wire)
- I will try to do it from below next time, with help, to save more insulation.
- I'll hot-melt glue it, good tip!
