The test method and solution of electronic components sealing

Abstract: electronic components are the general term of components and devices, which are different products, but for the convenience of people in the industry, they are collectively referred to here The common electronic components in industrial production are capacitors, resistors, inductors, crystal diodes, etc., while relays, diodes, triodes, sensors and other commonly used industrial electronic products are also electronic components Although there are different kinds of subordination and different purposes, they all play an irreplaceable value in the electronic technology industry of our country Taking mfy-02 sealing tester of Jinan Saicheng as an example, this paper makes a special test on whether there is leakage of electronic components produced by a manufacturer under vacuum Through the detailed record of the test process, test results and other data, it provides a reference direction and method for the majority of enterprises in need Key words: electronic components, electronic components, packaging leak detector, sealing tester, vacuum leak detector, vacuum sealing tester The purpose of sealing performance is the reliability of soft packaging seal Through this test, the integrity of the whole product packaging seal can be ensured This group of electronic component samples provided by a manufacturer is a part used in the manufacturing of medical devices The outer layer is made of thin aluminum alloy, which is equivalent to an empty rectangular box, and the inner part is specially used to store important components of devices In order to ensure the normal use of the devices and give full play to their social functions, it is necessary to ensure that the products in this rectangular electronic device are not affected by the external environment, that is, heat resistance, humidity resistance, light resistance, etc 2 The executive standard GB / T 15171-94 test method for sealing performance of soft package 3 Test sample electronic components produced by a manufacturer (Note: the sample is provided by customers of Jinan Saicheng) 4 Test equipment "mfy-02 sealing tester" independently developed by Jinan Saicheng has met a number of national and international standards: GB / t 15171, ASTM d3078 5 Test process description: according to the customer's requirements, 10 samples shall be tested one by one for 30s under the vacuum conditions of - 30, - 40, - 50, - 60, - 70 respectively, and the leakage shall be observed and recorded (1) Inject distilled water parallel to the crimping plate into the vacuum chamber, put sample 1 under the sealing cover, and then immerse it in water (2) start the instrument, set the parameters, set the pressure to - 30KPa and the time to 30s, and click the "confirm" button (3) the air source unit starts to extract the air in the vacuum chamber When the pressure in the vacuum chamber reaches the preset - 30KPa, it will automatically enter the test state (Note: the mfy-02 sealed tester developed by Jinan Saicheng is a domestic gas source unit, which does not need to be connected with external sources, plug in and use it) (4) observe whether there are continuous bubbles during the vacuum holding period within 30s (5) after the instrument stops automatically, open the air inlet valve, open the sealing cover at the same time, take out the sample, wipe the surface water to see whether there is water penetrating into the sample (6) put sample 1 into the vacuum chamber again, set the pressure to - 40kpa, keep the time unchanged, and start the test (7) if sample 1, repeat the above test for the remaining 9 samples Except that the time parameters are set to 30s, the sample and pressure need to be adjusted continuously 6 The test results are as shown in the figure "√" indicates no bubble and no leakage "×" indicates that there is bubble and there is leakage, in which whether the bubble is obvious and continuous is also recorded in detail for customer analysis 7 Conclusion the mfy-02 sealing tester developed by Jinan Saicheng ”For the domestic few built-in air source units, i.e without external air source, plug-in and use, and the pneumatic components adopt the world-famous imported SMC, the performance is more durable, stable and reliable, the data greatly facilitates the user's operation and the analysis of the results, which is a professional high-precision and rate instrument worthy of selection and trust by the manufacturer As a modern high-tech enterprise integrating R & D, manufacturing, sales, training and service, Jinan Saicheng has always been committed to continuously delivering more advanced and human-oriented instruments to the market, innovating technology and leading the industry More comprehensive acceptance of non-standard customization, before purchase can be in accordance with the customer's requirements for targeted testing, to ensure that the purchased instrument 100% applicable For more questions about the instrument, please call Jinan Saicheng technology directly!
