Leakage测试的意义在于在 Open-Short 测试之后，对芯片的输入IO，进行漏电流测试。 可以尽早发现IO结构问题。 为接下来的功能测试做准备。 Leakage 主要测试数字输入IO的漏电流测量IIH/IIL, PULL HIGH/PULL LOW。 IIL测试 ：IIL是对IO进行驱动低电平 (L)时测试输入IO (I)中的电流 (I); IIL测试测量从输入引脚到VDD的电阻。 进行 IIL 测试时，首先电源端施加 VDDmax，所有的输入管脚通过 Pin Driver 施加 VIH. 预处理为逻辑 1 状态；接着通过切换将 DC 测量装置（如 PMU）连接到待测的管脚，驱动 低电平输入，测量其电流并与期间规格书中定义的 IIL 边界进行比较；完成后再切换到下一个待测引脚。

The leak testing (or " leak test ") is the industrial proceedings necessary to verify and to measure the pneumatic tightness of the produced components. Particularly this document is made for the technicians employed to the end line testing of serial products. This phase of the industrial process is also called leak test or leakage detection .

洩漏測試 Leaking test. 密閉或封裝零件之所以需要密閉就是避免外在氣體、水份、空氣進入零件內，或零件內液體/氣體洩漏至外部來影響零件本身功能、汙染到其他部件。. 常見測試密閉性的包括電池、汽車相關的零配件，例如電池的封裝、電池芯避免電解液洩漏 ...
Ponding test with fluorescent dye gives the direct prove of the water leakage. With the aid of UV photography , the fluorescent effect can be clearly inspected on the affected area (e.g. ceiling) if the fluorescent dye water leaks from the possible source of water leakage (e.g. bathroom)
2020年2月8日 · A leak test is a procedure used to determine if an object, product, or system functions within a specified leak limit. A leak occurs when a gas or liquid flows through an object via an imperfection or manufacturing defect such as a hole, crack or weak seal.
leakage test in which a liquid containing a dye or fluorescent oil is driven by a pressure differential into the leak in the wall of the object to be tested and is then detected by a visual inspection on the other side
