If you really need to remove the ribbon -- it's just stuck onto barbed bosses in the plastic. Get close to the attachment point and carefully pull directly up from both sides, they'll come off. The substrate is undoubtedly a polyester film, quite tough. The conductors are more fragile, being thin copper foil; and connections to the outside tend to be more delicate yet, involving tiny crimps and maybe conductive paint. Some flexible wiring circuits are actually made with conductive paint throughout. Having the foils encapsulated between two layers of film protects them but makes them a good deal harder to fix, as it can be difficult to expose the copper without cutting or abrading it. -- David Beierl - Providence RI USA -- http://pws.prserv.net/synergy/Vanagon/ '89 Po' White Star "Scamp"
