Slipping with a knife can sever the fine copper wire, rendering the card entirely worthless.Action 2: Inspecting the Circuit Board
As soon as the plastic shell is split open, carefully move out the internal printed circuit board (PCB). Utilize a magnifying glass or a smartphone electronic 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 gently pushed.Step 3: Resoldering Faulty ConnectionsHeat up a fine-tip soldering iron.Use a tiny 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 blocking electrical continuity.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.
