Aerospace PCB Rigid-Flex Bend Zones: Protect Copper and Connector Interfaces

Aerospace PCB rigid-flex can remove a cable, reduce assembly volume, and simplify an avionics package, but it also moves risk into the board’s flex zone. The design can pass electrical checkout and still develop intermittent opens after deployment if the bend is treated as a packaging convenience rather than a controlled mechanical feature. For an...

Aerospace PCB Connector Grounding: Where the Board, Backshell, and Chassis Meet

In an aircraft or spacecraft avionics bay, a connector is not merely a mechanical boundary. It is where fast edge currents, cable shields, PCB reference planes, enclosure metal, and installation tolerances meet. A board can pass a schematic review yet radiate or pick up interference after integration because the signal return is forced through a...
