Slipping with a knife can sever the fine copper wire, rendering the card totally ineffective.Action 2: Inspecting the Circuit Board
Once the plastic shell is divided open, gently move out the internal printed circuit board (PCB). Use a magnifying glass or a smart device camera focused to check the board. Search for:
Micro-fractures in the solder joints, especially around the IC chip and the internal battery holder.Loose elements that wobble when carefully pushed.Step 3: Resoldering Faulty ConnectionsWarm up a fine-tip soldering iron.Apply a small amount of fresh electronic solder flux to the suspect joints.Carefully reflow the solder on the weak connections. The goal is to remelt the existing solder to bridge any tiny cracks that are obstructing electrical connection.Step 4: Testing and ReassemblyBefore gluing the plastic case back together, take the circuit board out to the car and test it in the card reader.
