EIAJED-4701-001 The environment and durability test method of semiconductor device, Australian electrostatic discharge generator is also in line with National military standard GJB548A-96 method 3015, national military standard GJB128A-97 method 1020, mil-MIL- STD-883D, EIAJED-4701.
1. Implementation of the test >
Static discharge generatorThe test should be performed in accordance with the test plan and directly and indirect discharge . It includes: > —— a typical working conditions of the test equipment;
—— whether the test device is based on desktop or landing equipment Test;—— Determine the applied discharge point;
-The on each point, use contact discharge or air discharge;
—— The test level used;
-The number of discharge times applied to each point in conformity test;
—— Whether the installation test is also carried out.
In order to formulate a test plan, some investigation test may be performed.

Test results and test reports
Gives the evaluation of the test results of the test results and the guidance principles of the test results of the electrostatic discharge generator static discharge generator . >
Due to the diversity and differences of the test equipment and systems, it is more difficult to determine the impact of the test on the equipment and the system. If the professional standardized technical committee or product technical specification does not give different technical requirements, the test cubs should be based on the test equipment >
The operating conditions and function specifications are classified as follows:
1.The performance within the technical requirements is normal;
2. The function or performance is temporarily reduced or lost, but it can recover by itself;
3. 3. Function or performance is temporarily reduced or lost, but the operator intervention or system reset;
4. Damage to the device (component) or software or the loss of data cannot be caused The function of restoring to normal state is reduced or lost.
The device should not have dangerous or unsafe consequences due to the test specified in this standard.
During the acceptance test, the description of the test program and test results must be described in a special product standard.
Generally, if the device shows its anti -interference degree during the entire test, and after the test is over, the test device meets the functional requirements in technical specifications, indicating that the test is qualified.
Static electricity generated between the body or two objects may cause electrical, electronic equipment The circuit fails and is even damaged. Therefore, the test of simulated electrostatic discharge is widely used worldwide.
Static discharge generator(ESD Generator) or ESD Simulator (ESD Simulator), commonly known as electrostatic electric gun (ESD GUN) is electromagnetic compatibility measurement and test static discharge -discharge resistance. Important equipment in the ESD Immunity test. The purpose is to check whether the electronic equipment can work normally when the electrical electrostatic discharge is discharged.
