Which Certificates Wire Harness Involved?

Which Certificates Wire Harness Involved? In the increasingly competitive wire harness market, product certification and factory certification shows particularly important, through the professional testing organizations to carry out strict quality control of product quality, you can effectively screen out qualified products, as well as high-quality suppliers, is a kind of protection for customers. 1- Product Certification RoHS 1. RoHS certification is a mandatory standard developed by the European Union. It is mainly used to regulate the material and process standards of electrical and electronic products, so that it is more conducive to human health and environmental protection. Rohs has been incorporated into the EU mandatory certification CE, generally only require a test report on it, but if the customer needs a certificate, you can also issue a CE certificate. It is mainly for the raw material of the product to be certified. Reach 2-Reach is only a test report, there is no certificate, REACH certification is the EU regulation “Registration, Evaluation, Authorization and Restriction of Legal Goods”. It is mainly for the raw materials of the product to be certified. Water-proof 3-Waterproof certification: First, we need to find out is the customer requirements of the material itself waterproof or design and manufacture of waterproof, which is our priority. About the material itself waterproof: the material itself waterproof means that the connector or wire and cable material can be used outdoors, will not be in the case of immersion in the physical deterioration. Manufacturing design waterproof: It means that after this product is designed and manufactured, this design will not enter water or dust, such as our common strain relief design. UL 4-UL: U.S. Security Laboratory certification, proving that the product meets U.S. safety standards. UL is mainly for North America, out of the U.S....

The key point of quality control of wire harness IPC620 Contact us to get IPC620 english version printed book I. Processes Involved in Wire Harness Manufacturing The processes involved in wire harness manufacturing include but are not limited to: Cutting: Refers to cutting electronic wires or cables to the required length using machines or manually, without damaging the insulation or outer sheath. Outer Sheath Stripping: The outer sheath usually refers to the cable sheath. The outer sheath stripping machine should not scratch or cut the insulation of the core wires when stripping the outer sheath. Any cuts, breaks, cracks or splits in insulation (not shown). u Insulation thickness is reduced by more than 20% . u Uneven or ragged pieces of insulation (frays, tails, and tags) are greater than 50% of the insulation outside diameter or 1 mm [0.039 in] whichever is more . u Insulation is charred . u Insulation is melted into the wire strands . Core Wire Stripping: Adjust the core wire stripping machine to the required size for stripping, and be careful not to scratch or cut the copper wires. Crimping: Select the appropriate blade according to the terminal size. Crimp the prepared wire with the terminal crimp part using the blade, ensuring a firm crimp and that the appearance and pull force of the crimped terminal meet the standards. Put on connector: Insert the qualified crimped terminal wires into the matching connector housing. A clear click sound will be heard when the connector is fully inserted. Wire Twisting: Adjust the wire twisting machine to the appropriate height to ensure that the copper wires are not flattened or tangled, and the twisted conductor is in a uniform spiral shape. Tinning: Apply flux to the prepared...
