| Abstract: |
| Objective To study on the correlation between atmospheric environment test of Xisha Ocean and laboratory environmental 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 laboratory, 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 accelerating 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. |
