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...

Alumina PCB for Automotive Sensors: Moisture, Vibration, and Connector Edge Decisions

Automotive sensor modules combine a ceramic substrate with a connector, housing, adhesive, shield, and sometimes a high-frequency antenna. The Alumina PCB is stable, but the assembled module still sees vibration, thermal cycling, condensation, and connector loads. The project pain is often a fracture or intermittent contact at an edge feature that was reviewed only as...
