As soon as the plastic shell is divided open, gently slide out the internal printed circuit board (PCB). Use a magnifying glass or a mobile phone camera focused to check the board. Search for:
Micro-fractures in the solder joints, particularly around the IC chip and the internal battery holder.Loose elements that wobble when carefully pushed.Action 3: Resoldering Faulty ConnectionsWarm up a fine-tip soldering iron.Apply a tiny quantity of fresh electronic solder flux to the suspect joints.Thoroughly reflow the solder on the weak connections. The objective is to remelt the existing solder to bridge any microscopic fractures that are obstructing electrical connection.Step 4: Testing and ReassemblyBefore gluing the plastic housing back together, take the circuit board out to the car and test it in the card reader.
