Initiator head with circuit board

An initiator comprising:

• an initiator shell extending in an axial direction, the initiator shell comprising:
• a shell wall defining a shell interior;
• and
• an explosive provided within the shell interior;
• and
• a head connected to the initiator shell at a first end of the initiator shell in the axial direction, the head comprising:
• a housing extending in the axial direction;
• a circuit board provided in an interior space of the housing, a thickness direction of the circuit board being substantially parallel with the axial direction;
• and
• a line-in terminal accessible from an exterior of the housing, the line-in terminal being in electrical communication with the circuit board;
• wherein the circuit board is configured to activate the explosive in response to a control signal received at the line-in terminal.

An initiator system comprising:

• an initiator holder;
• and
• an initiator received within the initiator holder;
• the initiator comprising:
• an initiator shell extending in an axial direction, the initiator comprising:
• a shell wall formed in a hollow tube shape defining a shell interior;
• and
• an explosive provided within the shell interior;
• a head connected to the initiator shell at a first end of the initiator shell in the axial direction, the head comprising:
• a housing extending in the axial direction;
• a circuit board provided in an interior space of the housing, a thickness direction of the circuit board being substantially parallel with the axial direction;
• and
• a line-in terminal provided on a first side of the housing in the axial direction and accessible from an exterior of the housing, the line-in terminal being in electrical communication with the circuit board;
• wherein the circuit board is configured to activate the explosive in response to a control signal received at the line-in terminal.
