Connector several basic test items, you know a few

　　In the 21st century, the development of science and technology tends to be highly refined, the quality of various electronic products has gradually improved, many consumers in the purchase of electronic products, focusing on the quality and service life of the product itself. Connectors also need to pass a number of tests to ensure that the verification of product features to meet consumer demand, so as to achieve long-term stability of the use of the effect.

　　How to produce such a quality connector to meet market demand, which requires a set of perfect quality system to manage, such as the current use of the most management system: quality management system ISO9001-2015, environmental management system ISO14001-2015, hazardous substances process management system QC080000. Guarantee quality, is inseparable from the excellent design and development, production and quality management team, and at the same time need to go through a number of modifications and testing and verification.

　　At present, the testing and verification involved in the connector is divided into five major items:

　　1、electrical performance testing

　　Divided into insulation resistance test, contact resistance test, withstand voltage test, temperature rise test. The purpose is: insulation resistance is to verify that the connector's insulation performance is in line with the circuit design requirements, high temperature and high humidity in the environment of its resistance value is in line with the provisions of the technical design.

　　2、FAI(Full-size Measurement Inspection Report)

　　It refers to the dimensions that are different from the key dimensions on the 2D drawing, but affect the critical form, fit, function or other relevant dimensions of the product.

　　3、Environmental Protection Test

　　That is, the test of hazardous substances, we often say RoHS, halogen-free, which RoHS is divided into RoHS1.0 and RoHS2.0. which RoHS1.0 for 6 items [ lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs) ]; RoHS2.0 for the 10 items (in the RoHS1.0 original 6 based on the addition of 4 items: 1. Diisobutyl phthalate DIBP, 2. 2-ethylhexyl phthalate DEHP, 3. Dibutyl phthalate DBP, 4. Benzyl butyl phthalate (BBP).

　　4、Mechanical performance test

　　Divided into insertion and extraction force test, vibration test, mechanical shock test, terminal (PIN) pin retention force test, terminal compression force (positive force) test and life test, etc., the purpose is: simulate the principle of the actual use of consumers, in accordance with the set parameters until the design requirements. Thus verifying whether the product performance can reach the designed range. Of course, each connector has a matching test items, these need to look at the professionalism of the inspector.

　　5、Environmental testing

　　(Including salt spray test, constant temperature and humidity) The purpose is: the product imitates the length of time used in harsh natural environments, salt spray test, high temperature and high humidity and various types of contact with the material applied to the product, after the completion of the test after the definition of the time to observe the phenomenon produced by the product is consistent with the set requirements.
