Slipping with a knife can sever the great copper wire, rendering the card totally worthless.Action 2: Inspecting the Circuit BoardOnce the plastic shell is split open, carefully move out the internal printed circuit board (PCB). Utilize a magnifying glass or a mobile phone camera zoomed in to check the board. Try to find:Micro-fractures in the solder joints, particularly around the IC chip and the internal battery holder.Loose elements that wobble when carefully nudged.Action 3: Resoldering Faulty ConnectionsWarm 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 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.
