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
