Claims3
A method of manufacturing an initiator head, the method comprising:
- injection molding a first housing piece that defines an interior chamber, a circuit board being positioned within the interior chamber;
- coupling a second housing piece to the first housing piece to cover the interior chamber;
- and
- filling the interior chamber with an insulating material thereby covering electronics of the circuit board with the insulating material;
- wherein the second housing piece is coupled to the first housing piece before the interior chamber is filled with the insulating material;
- and
- filling the interior chamber comprises injecting the insulating material into the interior chamber via a hole defined through the second housing piece.
