Abstract: |
Objective To study on the environmental adaptability of printed circuit board for airborne electronic equipment in Xisha environment. Method The exposure test on two kinds of printed circuit boards in Xisha marine environment was carried out by exposure for 3 years, and the aging characteristics were studied by appearance, insulation resistance, pressure resistance and quality factor. Results The insulation resistance and quality factor of the two types of printed circuit board samples showed an overall downward trend. PCB2 insulation resistance decreased relatively small. PCB1 sample had breakdown and obvious corrosion in withstand voltage test. Conclusion The environmental performance of PCB2 process system is better than PCB1. It is recommended of priority in selecting printed circuit board for airborne electronic equipment . |
