CMT = COMPRESSION MOUNT TECHNOLOGY

CMT is a contact technology between an electro-mechanical component (e.g. connector or test adapter for semi-conductors) and a printed circuit board (PCB).

The electrical contact is established through the compression of the two contact faces by screwing the component to the PCB. A stiffener is screwed from the backside to avoid stress on the PCB.
