AEC-Q102的功率温度循环PTC和双85试验的条件是什么？
AEC-Q102的功率温度循环PTC试验
施加驱动电流使结温达最大允许值，5min开/5min关
温区停留时间：至少10min
低温：-40℃
高温：
PTC condition 1: max Tsolder=85℃
PTC condition 2: max Tsolder=105℃
PTC condition 3: max Tsolder=125℃
AEC-Q102的双85试验
测试条件如下表：
6a | Wet High Temperature Operating Life | WHTOL1 | D,G,X,Y | 26 | 3
Note B | 0 | JEDEC JESD22-A101 | Only for LED and Laser Component.
PC before WHTOL1.
Duration 1000h at Tsolder=85℃/85% RH with drive current according to derating curve to achieve max Tj defined in the part specification.Operated with power cycle 30 min on /30 min off
TEST before and after WHTOL1.DPA after WHTOL1. |
6b | Wet High Temperature Operating Life | WHTOL2 | D,G,X,Y | 26 | 3
Note B | 0 | JEDEC JESD22-A101 | Only for LED and Laser Component.
PC before WHTOL2.
Duration 1000h at Tsolder=85℃/85% RH with minimum drive current according to part specification.if no minimum rated drive current is specified,a drive current shall be chosen not to exceed a rise of 3 K for Tjunction.
TEST before and after WHTOL2.DPA after WHTOL2. |
6a、WHTOL1：双85条件下施加一定的驱动电流使得结温达到最高允许值，30min开/30min关
6b、WHTOL2：双85条件下施加最小驱动电流、如无最小电流则施加不使结温超3K的驱动电流
一方面，是器件在温度、湿度加速应力条件下的寿命试验,另一方面，是考验器件在高温高湿偏压条件下的湿气抵抗能力
