Hoe soldeer ik losse draden op een flexibele printplaat??

Try to repair electronic sphygmomanometer now. It seems wires fell off from the flexible PCB, leaving trail on there. How do I solder them to the flex-PCB?

There are a few methods you can use to solder loose wires to a flexible PCB.

  • One is to use a soldering iron with a thin, pointed tip.

Hold the wire in place against the PCB and touch the soldering iron to the wire and PCB at the same time.

Apply pressure and heat until the solder melts and joins the wire and PCB together. Be careful not to overheat the solder or PCB, or you could damage them.

  • Another is to use a soldering gun with a wider, flat tip.

Hold the wire in place against the PCB and touch the soldering gun to both the wire and PCB.

The gun will heat up the wire and PCB, melting the solder.

Join the wire to the PCB by holding pressure and heat until the solder joins them together. Opnieuw, be careful not to overheat the solder or PCB.

 

Once the wire is soldered to the PCB, allow it to cool before moving it.

Once it’s cooled, you can test the connection by applying power to the PCB.

If everything is working correctly, the wire should light up or do whatever it’s supposed to do. Als niet, you may need to re-solder the wire.
