请教空气放电点的选取问题

aoizip12

依照法規來看, 測試點的首選是接觸放電,當無法使用接觸放電測試的點才會使用空氣放電.
法規條文如下: 請參閱
5 Test levels
The preferred range of test levels for the ESD test is given in Table 1.
Contact discharge is the preferred test method. Air discharges shall be used where contact discharge cannot be applied. Voltages for each test method are given in Table 1. The voltages shown are different for each method due to the differing methods of test. This does not imply that the test severity is equivalent between test methods.

非金属部分及结合处用空气放电测试，测试方法一定要符合规定要求

打两种没错，当两种测试方法产生不同结果有争议的时候，以接触放电为准。为什么？接触放电比空气放电的重复现高，请细读标准。
