Repairing superfine wiring

[pentium]

I ended up with a Sony PMW-EX3 that was in a pretty nasty fall. At this point I've repaired everything but the wire harness that brings video to the LCD viewfinder. It's this bundle of several dozen wires 0.3mm in diameter that has one clearly broken wire and several others either questionably intact or with damaged insulation. I can splice them but I have no idea how to insulate the repairs.



The smallest shrink tube I have only reduces to about 0.8mm and wouldn't work. The harness can't have the wiring completely replaced due to the special crimped ends and so far the best I've gotten out of Sony is that they no longer sell replacement parts for this model camera anymore.

Investigate if it would be possible to use flat flex cables .. solder the wires to the ends of the ribbon cable (possibly cut in several less wide segments and stacked on top of each other)

Here's an example ... about 3$ for a strip with 23+ wires, 0.3 mm pitch: http://www.digikey.com/products/en/c...t+ribbon+cable

From what I'm reading there I think that doesn't shrink small enough.

Are you sure? Says 1:5 ratio. I think the maximum size spec is just worst case scenario?

Some nail paint might work, i've used it to protect some components form corrosion.

Re: Repairing superfine wiring

can you not run new wires instead of repairing them ?

No the ends are crimped and so small that trying to pry it back apart is going to open a can of worms.
