| Objective To study the methods to improve the adaptability of photoelectric encoder in hydrothermal environment. Methods This paper analyzed the causes for the low adaptability of photoelectric encoders in hydrothermal environment in a certain military electronic system, and then formulated some corresponding process improvement methods. Results According to the analysis, moisture entering into the photoelectric encoder and the joint of core wires was the cause for the high failure rate. This paper proposed the corresponding solution. As verified by the test results, no moisture entered the photoelectric encoder and the joint of core wires after implementation of the process improvement methods. Conclusion The new methods were verified to be effective by later experiments, and therefore the adaptability of photoelectric encoders in hydrothermal environment was greatly improved. |
