| Abstract: |
| Advantages and disadvantages of electronic product specimen treatment by condition restoration method after low-temperature environmental test were analyzed comprehensively. The main causes of water condensation on test-piece by direct and rapid temperature rise method were analyzed. Two methods were put forward to solve the problem. Verification test result showed that the methods are scientific, reasonable, simple, and effective. |
