Opening the unit: medium difficulty
- Ordinary circuit board, no gel, in a sealed aluminium housing.
- On most versions the lid is bonded with a sealant bead and one edge of the board sits in thermal compound; levering there can bend the board.
- The boot contact on the board is small; overheating it has broken tracks in documented cases.
- Most versions can be read and written through the connector, so opening is rarely needed.
Advice: Check first whether the job can be done without opening it. If you open it, cut the sealant, never lever on the board, and reseal it afterwards.
General information: units with the same name can differ. Follow your tool's connection guide.
