What is acceptable ways of soldering wires directly to PCB?
There are eyelets also which are pressed into a PCB hole. Having said this, if your wires are smaller than #25 AWG and/or will not see any pulling stresses, you could even get away with soldering the wires directly to the board. Re: What is acceptable ways of soldering wires directly to PCB?
What’s the best way to trace a PCB?
1. The ability to solder (I’m sure you already know that by know) 2. A soldering Iron (the smaller the tip, the easier it is to solder small traces!) 3. Solder 4. A PCB or something with a trace 5. Something to scrape the trace with (an exacto knife or screwdriver or something else thin)
How do you put solder on copper wire?
You should put a dab of solder on your wire or component using flux and cover the revealed copper trace with solder. If you don’t have flux, you can still coat your wire (braided wire usually works best). This will make things much easier. Step 4: Solder! Now go ahead and solder your component/wire to the PCB.
What’s the best way to keep wires from falling off?
Agreed, the way to stop wires falling off is to avoid flex anywhere near the soldering point. Loom them and use a cable tie through 1 or 2 holes in the PCB to mechanically restrain them against movement. BTW, the wire shown in the OP photo appear to be silver plated, PTFE insulated.
How to re-solder a broken flex cable?
Remove the third lead, this will let you clear/prepare the pads for re-soldering. It’s probably best to flick the old solder off the leads; do this by heating and bending the lead with the tip of the iron and letting it spring back, DO NOT DO THIS TOWARDS YOUR FACE! You can buy solder with a flux core.
First the damaged volume/power flex cables are removed from the PCB, then a good volume flex cable is removed from a donor PCB and attached to the target PCB. Then a good power button flex cable is removed from the donor PCB and attached to the target PCB.
What kind of wire do you use for solder?
BTW, the wire shown in the OP photo appear to be silver plated, PTFE insulated. This is often used in aerospace but is the worst for solder wicking and fracture near the ends. It’s an absolute requirement that these are physically restrained away from the solder connection.
