Hi Joyce! Edge fingers, they plug into mating connectors on another board. regards, Graham Collins Senior Process Engineer Sunsel Systems (902) 444-7867 On 8/21/2015 8:26 AM, Yuan-chia Joyce Koo wrote: what is the gold pad for? wire bonding? zif? you got different repair... if it is wire bonding, you can forget it (on my watch if it is), unless it is stripped and replate.

So I know it is possible to get a kit with the chemicals and gear to allow re-plating the fingers, we are looking at it but my questions are: 1) what is the best kit, does anyone have a recommendation (or warning)? 2) does anyone offer this as a service? I've only got the 20 boards like this, the cost per board will be fairly substantial and this has not historically been a recurring issue. -- regards, Graham Collins Senior Process Engineer Sunsel Systems (902) 444-7867 ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
