摘要

传统的温度、湿度、偏置(T.H.B.)试验作为一种抗湿性测试方法,得到了广泛的应用。然而,在测试集成电路,特别是线性电路时,将所有电路元件置于反向偏置截止条件下是极其困难的。T.H.B.测试通常在实际操作条件下进行。由于功耗大,导致结温升高,器件内湿度降低。因此,不认为该试验是在预期的高湿度条件下进行的。因此,传统的T.H.B.测试被认为不是集成电路的合适测试方法*

A New Cyclic Biased T.H.B. Test for Power Dissipating IC's
As a test method for moisture resistance, conventional T.H.B. (Temperature, Humidity, Bias) Test is being widely used. However, in testing integrated circuits especially linear circuits, it is extremely difficult to put all of the circuit elements under reverse bias cutoff conditions. The T.H.B. Test is usually performed under an actual operating condition. As a result, the junction temperature increases due to a large power dissipation, and the humidity level in the devices decreases. Consequently, the test is not considered to be conducted under the intended high humidity condition. For that reason, the conventional T.H.B. Test is not thought to be a proper test method for integrated circuits*
