As millimeter-wave technologies continue to advance in the printed circuit board (PCB) industry, there are emerging needs for more diverse circuit constructions. A previous limiting factor for complex millimeter-wave PCB constructions, had been appropriate bonding materials to accommodate the circuit fabrication as well as the demanding RF performance at these high frequencies. These issues have been addressed in the following blog.
A global push to reduce CO2 emissions, as well as government incentives and consumer demand, is leading the world’s largest automotive manufacturers to accelerate plans to introduce all-electric and hybrid-electric (EV/HEV) models.
Twelve countries around the globe have set goals to end the sale of gas- and diesel-powered vehicles starting in 2040. This will significantly accelerate the uptake of electric vehicles (EVs) and hybrid vehicles (HEVs). It will also increase the need for improved battery management systems to monitor and control the high-voltage battery stacks, and for power semiconductor devices for battery management, on-board charging, infotainment, electric motors, and more.
Millimeter-wave frequency bands hold valuable spectrum for what lies ahead: fifth-generation (5G) wireless communications and automotive collision-avoidance radar systems. Signals at 60 GHz and higher might have once been thought too high to transmit and receive with affordable circuits. But semiconductor devices and circuit technologies have improved in recent years and millimeter-wave circuits are becoming standard electronic equipment in many car models.
A Chinese automobile manufacturer identified an issue with water leaking into the brake light of one of its models, causing short circuits and potentially a fire. The deterioration of the EPDM material originally used to seal around the brake light caused the leakage.
Power electronics is changing rapidly. New packaging technologies are facing a rise in chip temperatures as seen in such applications as EVs / HEVs. Electronics increasingly need longer lifetimes to function in harsh conditions, such as wind turbines.
Recent developments in eMobility (electro mobility or advanced mobility) have led to increasing options for clean and efficient vehicles that rely on electric powertrain technologies, in-vehicle information, communication technologies, and connected infrastructures. The systems within these vehicles pose unique sealing and vibration management challenges vs cars with traditional combustion engines.
