I have snapped of the connector of my antenna interconnect cable on my dock flex cable. I have another dock flex cable which doesn’t work, and I was wondering if it would be possible to desolder it, and solder it onto the working one. What connections need to be made? What is the risk involved? Will I need anything other than a vacuum desoldering pump, a soldering iron and solder? Thanks!
Just use a soldering iron with a fairly fine point tip and some desoldering wick. This is much too small to use a desoldering pump. Generally the central core of the wire is soldered at the end and the sheathing is soldered separately (you can see it pretty well here on Step 33 of this guide) Don’t underestimate the difficulty of soldering/desoldering fine wires on soft flexes. Too much heat and you will do a lot of damage.
