Slipping with a knife can sever the great copper wire, rendering the card completely ineffective.Step 2: Inspecting the Circuit Board
As soon as the plastic shell is divided open, carefully slide out the internal printed circuit board (PCB). Utilize a magnifying glass or a smartphone video 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 components that wobble when carefully nudged.Step 3: Resoldering Faulty ConnectionsWarm up a fine-tip soldering iron.Use a small amount 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 tiny cracks that are obstructing electrical connection.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.
