Vibration test introduce in IEC 60068 and application in lighting industry

IEC (International Electrotechnical Commission) is the earliest international standardization organization in the world. It was established in 1906 to enhance international mutual understanding and hope that national committees can use these international standards if their own conditions permit IEC is mainly responsible for international standardization of electrical engineering, electronic engineering, telecommunications and atomic energy.

IEC60068 standard vibration test includes sinusoidal vibration test and broadband random vibration test And refer to standard chapters: IEC60068-2-6, IEC60068-2-64.

IEC60068-2-64 random vibration test, package test standard involves structural integrity The scope of the transportation test standard is the random vibration of the equipment under dynamic load.

IEC6008-2-6 vibration (sinusoidal) test standard sinusoidal vibration test method environmental test for electronic products Part II. This part gives the standard test method process to determine the ability of components, equipment and other products to withstand the specified severe sinusoidal vibration The purpose of this experiment is to determine the mechanical weakness and characteristic degradation of the sample.

Vibration test can be applied to automobile parts, electronic components, components, medicine, food, furniture, gifts, ceramics, packaging and other industries Relevant vibration tests are carried out on samples in the laboratory and production line to improve product reliability Here, the vibration test is mainly used to describe the lighting industry.

Why should the lighting industry conduct vibration testing?
1. Design and development stage.
2. Analyze the vibration modes of the test object under different vibration states.
3. Test the ultimate strength of the product and determine relevant characteristic specifications
4. Failure analysis and improvement.

Production stage
Comprehensive ESS(environmental stress screening) test was carried out to screen out a large number of potential defects (according to the product characteristics and vibration scale, the potential defective parts can be effectively screened out through ess test, and the effect of eliminating the residual stress in the electronics or mechanisms and the residual thermal stress and internal stress during processing can be effectively eliminated, and the discrete capacitance effect between multilayer circuit boards can be effectively eliminated, which will provide considerable help to the product quality.)

Quality Control: Effectively ensure and manage product quality level.
Quality management: The use function, specification and reliability of the certified products are the same as those indicated.

What results can be obtained from the vibration test?
1. Provide basis and reference for project development
2. Process control
3. Quality improvement and promotion
4. Provide conditions related to vibration
5. Guarantee of product quality yuchengruo
6. Reduce maintenance expenses and increase profitability
7. Improve the overall image

Defects that can be screened by vibration test
1. The fastener is loose
2. The electronic contact is poorly connected
3. Screen out potential defective parts
4. Select defective solder joints
5. The vibration position and accuracy of the adjusting part are distorted
6. Breakage and damage of parts and components
7. Abnormal circuit disconnection and short circuit
8. Abnormal wear of power or signal wires, broken wires or loose contacts
9. The test piece produces vibration noise
10. Abnormal function failure
