Essential Warning: Be incredibly cautious near the leading edge of the card where the internal antenna coil is situated. Slipping with a knife can sever the fine copper wire, rendering the card entirely ineffective.Step 2: Inspecting the Circuit Board
Once the plastic shell is split open, carefully move out the internal printed circuit board (PCB). Utilize a magnifying glass or a smart device camera focused to inspect the board. Look for:
Micro-fractures in the solder joints, especially around the IC chip and the internal battery holder.Loose elements that wobble when gently nudged.Action 3: Resoldering Faulty ConnectionsWarm up a fine-tip soldering iron.Use 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 microscopic cracks that are obstructing electrical connection.Step 4: Testing and ReassemblyBefore gluing the plastic casing back together, take the circuit board out to the car and test it in the card reader.
