Advanced electronics in aerospace applications experience temperature fluctuations. A good aerospace PCB thermal management system isolates sections with different temperatures and maintains the desired thermal operating environment. Hence, precise thermal control is mandatory for the prolonged functionality of electronic components on the board. Aerospace subsystems use different categories of circuit boards as shown in the image. Aerospace electronic subsystems The graphic illustration below shows a few applications of PCBs in the aerospace industry: Applications of aerospace PCBs Design guidelines for aerospace PCB thermal management The typical operating temperature of an aerospace board is between –50 to 125ºC. Parameters that…
