| 摘 要： | 目的考察机载电子设备印制电路板在西沙环境下的环境适应性。方法开展西沙海洋环境下2种印制电路板的棚下暴露实验,暴晒实验时间为3年,分别通过外观、绝缘电阻、耐压性、品质因数研究其老化特点。结果两类印制电路板样品的绝缘电阻和品质因数呈总体下降趋势,PCB2的绝缘电阻下降相对较小,PCB1样本耐电压测试出现击穿并有明显的腐蚀情况。结论 PCB2工艺体系的环境适应性能好于PCB1,在机载电子设备印制电路板选用过程中推荐优先。

| 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 . |
