With the gradual development of consumer electronic products towards lighter, thinner, and more intelligent applications, higher requirements have been put forward for display technology and data transmission processing capabilities. The diversification of applications and the thinning of volume have also prompted printed circuit boards to arrange more wires in limited areas, continuously developing towards ultra-fine directions such as fine line width, dense wiring, and precise craftsmanship. High density, thinness, flexibility, rigid flexible combination, and environmentally friendly production have gradually become the direction of future development.

Industrial control motherboard is a motherboard used in industrial applications and is adopted by industrial computers. It can adapt to wide temperature environments, harsh environments, and long-term high load work according to requirements.

The 5G optical module PCB circuit board, also known as the 5G mixed pressure gold-plated board, is made of Lianmao IT968TC high-speed material and produced using the production process of mixed pressure, surface and local thick gold plating. It is widely used in 5G communication optical modules.
