[SBE] Loose Circuit Board

[McGlothen, Darryl]

Rubbing the card edge connector with a soft pink eraser (see your grandkid for a sample)is not likely to damage the 'plating' unless you do it excessively long and/or vigorously. We have been using this technique to clear up intermittant and 'dirty' connections for years with no adverse effects. Much cheaper (and safer) than expensive chemicals.
