The development of science and technology in the 21st century tends to be more sophisticated, and the quality requirements of various electronic products are gradually improving. When purchasing electronic products, many consumers still pay attention to the quality and service life of the products themselves. Pin header connectors need to pass a number of tests to ensure that the functions of the verified products meet the needs of consumers, so as to achieve long-term and stable usage.
How to produce this kind of pin header connector that can meet the market demand requires a complete quality system to manage, such as the current management system with the most usage: quality management system ISO9001-2015, environmental management System ISO14001-2015, hazardous substance process management system QC080000, etc. Guaranteeing quality is inseparable from excellent design and development, production and quality management teams, and also requires repeated revisions and test verifications.
At present, test items of pin header connectors is divided into five major parts:
1.FAI (full-scale measurement inspection report)
Different from the key dimensions on the 2D drawing, it’s the other dimensions which would affect key form, matching performance and function of the product.
2. Mechanical performance test
It is divided into insertion and withdrawal force test, vibration test, mechanical shock test, contact holding force test, contact pressing force (positive force) test and life test, etc. The purpose is to imitate the principle in the actual use of consumers. According to the set parameters until reaching the design requirements, so as to verify whether the product performance can reach the designed range.
3. Electrical test
Electrical test is divided into insulation resistance test, contact resistance test, withstanding voltage test, temperature rise test, etc. Insulation resistance is to verify whether the insulation performance of the pin header connector meets the requirements of circuit design, and whether its resistance value meets the rules of technical design in a high temperature and high humidity environment.
4. Environmental testing
It Includes salt spray test, constant temperature and humidity. The product simulates the it is used in a natural and harsh environment, after the time test is completed, check whether the phenomenon produced by the product meets the set requirements.
5. Environmental testing
That is also called testing of harmful substances, we often say RoHS, halogen-free/HF. RoHS is divided into RoHS1.0 and RoHS2.0. Among them, RoHS1.0 contains 6 items [lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs)]; RoHS2.0 contains 10 Items (Add 4 items on the basis of the original 6 items of RoHS1.0: 1. Diisobutyl phthalate DIBP, 2. 2-Ethylhexyl phthalate DEHP, 3. Phthalic acid Dibutyl ester DBP, 4. Butyl benzyl phthalate (BBP).
CNT insist on providing high quality pin header plug connector to customers, all pin headers must pass all above tests. And all materials meet ROHS, REACH requirement.
