可靠性加严
除了标准可靠性认证外，通过大样本量ELFR测试，延长实验以及过压老化等维度来评估较强的可靠性本征能
大样本量测试(ELFR)
| Items | Condition | Sample Size | Duration | #Fail |
|---|---|---|---|---|
| HTGB | Tjmax, Vgsmax | 800ea*3lots | 48H~168H | 0 Fail |
| HTRB | Tjmax, Vdsmax | 800ea*3lots | 48H~168H | 0 Fail |
可靠性延长测试
| Items | Test Condition | Standard Test Duration | INNO Extended Test Duration | #Fail |
|---|---|---|---|---|
| HTGB | Tjmax, Vgsmax, 1Lot*77ea | 1000H | 2000H | 0 Fail |
| HTRB | Tjmax, Vdsmax, 1Lot*77ea | 1000H | 2000H | 0 Fail |
| H3TRB | 85℃,85%RH,80%Vdsmax, 1Lot*77ea | 1000H | 2000H | 0 Fail |
