In the flexible circuit board industry, multiple important industry standards and certifications constitute the core of this system. Among them, UL94 combustion certification is a key standard for measuring the flame retardant performance of flexible circuit boards. Customers usually choose V-0 or VTM-0 combustion rating to ensure that the product has sufficient fire safety during use.
In addition, the UL796 standard is specifically designed for testing printed circuit boards (PWBs), covering a wide range of testing requirements and performance indicators. In addition to UL standards, ISO9001 quality management system certification is also an important certification that flexible circuit board production enterprises must pay attention to. This international standard emphasizes continuous improvement, customer satisfaction, and compatibility with other management systems, providing a comprehensive framework and guidance for quality management in enterprises.
There are also strict regulations on the testing methods and standards for flexible circuit boards. The testing scope covers single-sided, double-sided, and multi-layer boards of flexible circuits, and the purpose of the testing is to establish a general rule for determining the appearance quality of flexible circuit boards.
The testing methods mainly use visual inspection, magnifying glass, and ruler as the main inspection methods and tools. If necessary, other applicable testing instruments or equipment may also be used for inspection. The basic testing standards include the appearance of the substrate film surface, the appearance of the coating layer, the deviation of the connecting plate and the coating layer, the flow and discoloration of the adhesive and the coating layer, the leakage of the coating layer, and the poor electroplating bonding. These testing standards and methods ensure quality control of flexible circuit boards during the manufacturing process, reducing unnecessary scrap and resource waste.
It is worth noting that with the continuous development of technology and changes in market demand, the standards and certifications of the flexible circuit board industry are also constantly updated and improved. Meanwhile, as different countries and regions may have varying regulatory and standard requirements, companies also need to understand and comply with local regulations and standards before entering specific markets to avoid potential market access risks.
In the process of building a standard and specification system for the flexible circuit board industry, it is also necessary to strengthen cooperation and communication within the industry. Industry associations, research institutions, and leading enterprises can jointly develop and promote industry standards, promote the continuous progress and development of the entire industry through sharing best practices and technological innovations. In addition, strengthening cooperation with the International Organization for Standardization and participating in the formulation and revision of international standards are also important ways to enhance the international competitiveness of China’s flexible circuit board industry.
The construction of standards and specifications for the flexible circuit board industry is a complex and systematic project that requires joint efforts from various parties such as the government, enterprises, industry associations, and international standardization organizations. By continuously improving and updating industry standards and regulations, strengthening quality management and technological innovation, promoting the healthy development of the flexible circuit board industry, and providing strong support for the innovation and upgrading of electronic products.
