Renault key cards, in specific, withstand a lot of tension when rested on in back
- pockets, causing cracked solder joints. Tools Needed for Circuit Board Repair: Precision soldering iron Amplifying glass or jeweler's loupe Plastic opening tool (spudger) Replacement micro-switches( if buttons are broken) Isopropyl alcohol and a cotton bud Fixing CrackedSolder Joints Over years of use, the tiny solder joints connecting the internal
