Board-to-Board Terms
Float
General term describing the board-to-board system’s physical ability to maintain a consistent RF signal between the PCB connectors and the bullet adapter.
Tolerance: The system’s ability to adequately mate and consistently perform in the least optimal mated condition.
Axial Misalignment: The minimum and maximum distance between mated PCBs, allowing the bullet to sit out of its nominal position.
Radial Misalignment: The maximum angle of the bullet adapter when mated between PCBs that still maintains consistent expected performance.
Detent
Term used to describe the PCB connectors mechanical mating strength or hold on the bullet adapter.
Limited Detent: Medium retention, good for lab environments and low to medium mechanical stress.
Full Detent: Provides fixed retention when mated, vibration resistant.
Smooth Bore: Slide-in mating, provides no mechanical retention feature inside the connector.
Catcher’s Mitt: Design feature describing the wide gathering cone of a PCB connector. Mostly seen with smooth bore detent, but not exclusively.
Blindmate
A design term used to describe the ability to mate the system without seeing the mating PCB connectors. Blindmate assembly typically requires generous manufacturing tolerance and high-float misalignment correction.
