A holistic view of 77GHz radar sensors as a PCBA build, considering fabrication, assembly and packaging materials.

The Society of Automotive Engineers (SAE) and US Department of Transportation classify levels of vehicle autonomy from 0 to 5. Level 0 incorporates no automation; levels 1-3 have varying degrees of partial assistance to the driver, where the automobile, for example, can control steering, acceleration and deceleration, and even interfere with the driver. Finally, in full autonomy, level 5, the car drives on its own and makes all decisions and reactions to its surroundings.1

The automotive market uses a combination of sensors to make these critical decisions. Radar designs are the fastest growing sensors in ADAS today, due to the longer-range capabilities and their resistance to all weather conditions.2 This research will focus on radar designs, specifically long-range 77GHz radar, to showcase how automotive materials are changing and, through the choice of alternatives to those conventionally used in the space, how product life and reliability can be enhanced.
