I'm replacing the SMD LEDs on my instrument gauge cluster in my truck with a new color LED. While attempting to remove one of the original LEDs, the solder pads came off from both the positive and negative contact points. One of the pads is salvageable (still attached to the light I removed), but the other is not. Please advise. It is neither visually appealing, nor safe to be traveling at night without an illuminated speedometer.
I visited a computer repair shop in town and they said if a solder pad is gone, there is no way to repair it. They advised me to buy a new instrument cluster at a cost of $150-$200.
Online I found a suggestion to fix. Buy silver based conductive epoxy. Place where pad was. Make sure it is touching an exposed lead. Either attach light to epoxy while curing, or let cure, then solder the light to the cured epoxy.
Also I saw a suggestion of using copper wire to make a bridge. With the method, I didn’t know where to scrape the green area to expose copper below. Nor what, nor where to connect that wire to beyond the LED. Also I had questions of how and where to create the new contact points, being that there is a positive and negative side. I’m sure the created new contact points wouldn’t be created too far away, but placement of the light is important because they are designed to be in the original place for a reason.
I am also open to any and all ideas I have not mentioned above.
