PCB reliability refers to the ability of "bare board" to meet the production conditions of subsequent PCBA assembly, and to maintain normal operating functions within a certain period of time under specific working environments and operating conditions.
As the carrier of various electronic components and the hub of circuit signal transmission, PCB determines the quality and reliability of electronic packaging. With the miniaturization, light weight, multi-functionalization of electronic products, and the continuous promotion of environmental protection requirements such as lead-free and halogen-free, the PCB industry is showing "thin lines, small holes, many layers, thin boards, high frequency, high speed. "The development trend, the reliability requirements will be higher and higher.
High-reliability PCB can play the role of a stable carrier to achieve long-term and stable operation of PCBA, thereby ensuring the safety, stability and service life of end products, and enterprises can then enhance competitiveness, enhance reputation, expand market share, and improve economic benefits .
