In the process of using or storing the mica board, its function will irreversibly degrade over time. The reliability of mica board operation largely depends on the aging characteristics of the insulation data. According to statistics, when FR4 board is used or stored, its function will be irreversibly degraded over time.
The reliability of mica board operation largely depends on the aging characteristics of the insulation data.
According to statistics, the failure rate of electrical equipment has a significant relationship with the use time of insulation data, and this correlation curve is called a slot curve.
Three areas in the curve:
1. Early defect areas are usually caused by material quality defects or subsequent manufacturing processes;
2. The random failure zone is mainly caused by abnormal conditions during operation;
3. The defect area is caused by aging, and the defect rate increases with the use of time.
