摘　　要：目的研究机载电子设备印制电路板西沙海洋大气环境与实验室环境试验的相关性。方法在西沙海域环境下开展两种印制电路板的棚下暴露试验,暴晒试验时间为3年,同时在实验室开展盐雾试验,分别通过测试绝缘电阻、品质因数研究两种试验环境的相关性。结果将以绝缘电阻、品质因数为基准相关性评价结果进行平均,得出印制电路板实验室加速试验和自然暴露试验存在着强相关。两种样品的加速系数分别是3.5,5.15。结论建立了印制电路板在西沙海洋环境试验和实验室盐雾环境试验的相关性,可为后续西沙环境试验的加速处理提供依据。Objective To study on the correlation between atmospheric environment test of Xisha Ocean and laboratory en-vironmental test of printed circuit board for airborne electronic equipment. Methods Shed exposure test for two kinds of printed circuit board were carried out in the Xisha sea environment for 3 years, while the salt spray tests weres carried out in the labora-tory, respectively, through the test appearance, insulation resistance, quality factor to study the correlation between the two test environments. Results By averaging the assessment result based on insulation resistance and quality factor, the results show that the laboratory accelerated test of the printed circuit board and the natural exposure test were strongly correlated. The accelerat-ing coefficients of the two materials were 3.5 and 5.15 respectively. Conclusion The correlation between the printed circuit board in the Xisha marine environment test and the laboratory salt spray environmental test is established, which can provide the basis for the accelerated treatment of the subsequent environmental test in Xisha.
