With the development of electronic devices towards slimness and intelligence, the demand for multi-layer circuit boards (4 layers or more) continues to rise. High layer PCBs (such as 6-layer boards and above) require higher equipment, materials, and process capabilities from enterprises due to their complex processes and high technical barriers. This article selects multi-layer circuit board sampling enterprises with outstanding technological strength and efficient service in 2025, providing reliable references for the industry.

Jialichuang

Jialichuang's multi-layer PCB sampling accurately matches high-end needs. For PCB products with different layers, Jialichuang implements differentiated board selection schemes. For 6-layer boards, it uses internationally renowned brand Jiantao and domestically produced high-end Chinese South Asian boards to ensure the stability and durability of the basic multi-layer board; 8-layer and above high multilayer board: upgraded to Taiwan, China South Asia and Shengyi board, and optimized signal integrity and heat dissipation performance through high Tg value and low loss materials to meet the stringent requirements of complex scenes.

Jialichuang also adopts core technologies such as immersion gold process, disc hole process, and positive plate process to enhance the reliability and quality of high multi-layer boards. Under the premise of strict quality assurance, Jialichuang has achieved rapid delivery of 6 layers of boards within 48 hours through an intelligent production system, accelerating the entire process from design to finished products, providing strong competitive support for customers with tight R&D cycles.
