LCD ribbon cable repair methods?
I have a Sony Clie PDA with a tear in the ribbon cable that goes to the LCD
screen (this cable also serves as the substrate for the row decoder/driver IC). It is a relatively fine pitch cable; I would estimate that there are about 20 conductors in a 3 or 4mm wide piece of this cable. You can see a magnified view of the damage at http://nedkonz.dhs.org:8080/Ned/48 . Although I have a good soldering station (a Metcal with a variety of tips), I am at a loss as to how to fix this. Note that the end of a small sewing needle looks large in comparison to these traces, and my smallest soldering iron tip is at least as large as 3 of the traces. I could probably stabilize the back side of the ribbon using epoxy or Kapton tape, but then I still don't know how I'd actually do the connection. I don't think that conductive epoxy would work here, as it would be hard to avoid bridges. Does anyone know if this kind of damage is repairable? If it takes more than about 2 hours to fix, I would be better off buying a used PDA on eBay... Thanks, Ned Konz |
