Step 2: Inspecting the Circuit Board

Once the plastic shell is split open, carefully move out the internal printed circuit board (PCB). Use a magnifying glass or a smartphone video 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 parts that wobble when gently nudged.

Step 3: Resoldering Faulty Connections

• Warm up a fine-tip soldering iron.
• Apply a tiny quantity 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 blocking electrical continuity.

Step 4: Testing and Reassembly

• Before gluing the plastic casing back together, take the circuit board out to the car and test it in the card reader.
