In the electronics manufacturing and assembly industry, the quality of cables and wiring harnesses is directly related to the performance and safety of products. As a leading PCBA manufacturer committed to quality excellence, we obtained the IPC/WHMA-A-620 certificate and use this standard to provide our customers with highly reliable cable and harness assemblies that meet global quality standards. Through strict quality control, we not only ensure the stability of products, but also bring obvious benefits to customers. IPC-A-620 certification is more than just a qualification, it is a strong demonstration of our commitment to providing high-quality products to our customers.
IPC/WHMA-A-620 Cable and harness assembly requirements and acceptance standards, the full form of IPC-A-620, is jointly developed by IPC (International Electronic Industry Connection Association) and WHMA (Harness Manufacturers Association) recognized quality standards for cable and harness assembly in the electronics industry. This standard specifies the design, production and inspection requirements of cable and harness assembly and is a reliable quality standard guide for manufacturers, providing clear guidance on all aspects of cable and harness assembly. Here are some aspects:
The IPC-A-620 standard makes detailed requirements for the assembly process of cables and wiring harnesses. For example:
Crimping (the process of mechanically binding the wire to the terminal to ensure the reliability of the electrical connection): IPC-A-620 specifies the shape, size, position and strength of the crimping in detail to ensure that each crimping contact meets the corresponding mechanical strength requirements to avoid loosening or breaking during use.
Soldering (a key process to ensure good electrical contact between wires and connectors): IPC-A-620 provides detailed guidance on welding quality, including standards for the appearance of solder joints, solder usage, soldering location, etc.: Solder joints should be free of obvious welding defects, such as cold soldering, overheating, too much or too little solder, etc. The solder joint should be smooth and free of burrs, and the welding area should not have insulation damage.
IPC-A-620 provides specific acceptance criteria and inspection procedures for quality control and visual inspection, including:
Acceptance criteria: IPC-A-620 standards (including the quality of electrical contact, the integrity of physical appearance, the solidity of welding and crimping, the integrity of insulation, etc.) describe the qualification conditions of cable and wire harness products in detail, and classify them as acceptable, and unqualified.
Inspection process: To ensure that each harness assembly meets the requirements of IPC-A-620, visual and functional inspection is required at each production stage, including checking the connectivity of wiring, whether the welding is complete, whether the insulation is damaged, etc. These inspection steps can significantly reduce the rate of defects, improve production efficiency and product quality.
