How to reattach LCD Ribbon Cable?
display attached to the main circuit
board with a ribbon cable, one end of which has come loose. My first instinct is just to heat up the individual traces but I can't tell if it was attached with solder or something else. Also I am nervous about melting the plastic backing or the ribbon cable. Does aanyone know how these things are normally attached and/or how to repair them? Thanks. -- Nelson "...one end of which..." So: Which END? The end normally connected to the LCD is connected with a "zebra" connector which relies on pressure only. The end normally connected to the PCB uses some other kind of connector, usually with a "latch" of some sort to secure the FPCB to the connector. It is a pretty good bet that soldering to the glass substrate in the LCD will not advance your cause. webpa |

How to reattach LCD Ribbon Cable?
There are a number of methods used. There is the one with the rubber type
of micro contact strip that works with pressure. There is the type where there is a ribbon cable, that is attached, by an adhesive. The process for this one uses a special adhesive that is attached with a heat die. If this type separates, a new ribbon is required, and the proper heat die is also required to heat it back. A soldering iron is not the way to go. -- Greetings, Jerry Greenberg GLG Technologies GLG ========================================= WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm ========================================= "Nelson" wrote in message ws.net...
