- Crucial Warning: Be very mindful near the top edge of the card where the internal antenna coil is situated. Slipping with a knife can sever the fine copper wire, rendering the card completely worthless.
Action 2: Inspecting the Circuit Board
Once the plastic shell is split open, carefully slide out the internal printed circuit board (PCB). Use a magnifying glass or a mobile phone cam zoomed in 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.
Action 3: Resoldering Faulty Connections
- Heat up a fine-tip soldering iron.
- Use a tiny quantity of fresh electronic solder flux to the suspect joints.
- Thoroughly reflow the solder on the weak connections. The goal is to remelt the existing solder to bridge any tiny fractures that are blocking electrical continuity.
