Aluminum Nitride PCB for mmWave Sensor Carriers: Geometry, Return Paths, and Thermal Margins

An Aluminum Nitride PCB sensor carrier must keep package geometry, RF return, and thermal margin visible in one controlled interface drawing. An mmWave sensor carrier must keep the feed geometry stable while moving heat away from the active device and preserving the enclosure datum. Aluminum nitride can support that combination, yet the first build can...
