Whether electronic equipment can work reliably is based on whether electronic components can work reliably. If the early failure components are installed on the whole machine and equipment, the early failure rate of the whole machine and equipment will be greatly increased, its reliability can not meet the requirements, and it will have to pay a great price for maintenance. Therefore, before the electronic components are installed on the whole machine and equipment, we should try to eliminate the components with early failure as much as possible. Therefore, we should screen the components.
General requirements for testing and screening of electronic components: 1 Non destructive test without changing the inherent reliability of components; 2. 100% screening of batch products; 3. Eliminate early failure products and improve the reliability of components; 4. The screening level is determined by the expected working conditions and service life of components.
The test and screening of electronic components involves a large number of instruments and equipment. The following is the list of relevant test items and testing instruments and equipment for the test and screening of electronic components:
Test items | Testing instruments and equipment |
Electrical test | Impedance analyzer |
LCR, ohmmeter, etc | |
Environmental and stress screening | High and low temperature test chamber: thermal cycle test |
Life / aging / aging test | Monolithic integrated circuit high temperature dynamic aging system |
Appearance inspection | optical microscope |
Seal detection | Helium mass spectrometer leak detector |
X-ray radiography | X-ray transmission system |
Scanning acoustic microscopy | Acoustic scanning detection equipment |
