High-Multilayer PCBs for Satellite Communication with Backplanes (20+ Layers)
Rigorous Material Selection: Substrate Ensuring Adaptability to Extreme Environments Satellite communication equipment operates in complex environments for extended periods, placing extremely high demands on the stability and resilience of the PCB substrate. The materials used in high-multilayer PCBs with backplanes (20+ layers) undergo rigorous selection. Long-term strategic partnerships have been established with leading material suppliers in the industry, such as Rogers, Taconic, Arlon, Kingboard, and Shengyi, utilizing high-frequency, high-speed substrates with low dielectric loss, high heat resistance, and excellent dimensional stability, along with high-performance FR-4 board materials, to meet the high-frequency signal transmission requirements of satellite communication. Simultaneously, high-quality auxiliary materials such as Rohm and Haas electroplating chemicals, Hitachi dry film, and Taiyo inks are used to ensure the electrical and mechanical properties of the board material from the source, resisting the impact of environmental changes on product performance and laying a solid foundation for the stable operation of multi-layer structures.
Precision Manufacturing Process: Key to the Forming of High-Multilayer Structures The interlayer interconnection, circuit forming, and shape processing of backplane-level PCBs with 20 or more layers all rely on high-precision processing technology and advanced equipment to ensure the accurate realization of complex structures. High-precision depth-controlled forming machines are used to complete the depth-controlled milling of complex mechanical structures in backplane-level products, adapting to the structural requirements of large-size, thick backplanes. For the shape processing of special materials, laser cutting technology is used to achieve high-precision, stress-free shape processing, avoiding damage to the internal structure of multiple layers. Through automatic solder mask coating equipment and specialized solder mask processes, a uniform and stable solder mask layer is formed, improving the product's insulation and safety, and adapting to the long-term operational requirements of satellite communication equipment. Mature hybrid lamination technology enables stable bonding of FR-4 with materials of different properties such as Rogers, Arlon, and PTFE, balancing high-frequency signal transmission and structural strength. It meets the interlayer bonding requirements of multilayer structures with 20 or more layers, eliminating defects such as delamination and bubbles, and ensuring reliable interlayer interconnection. Fine circuit processing capabilities reach 2.5/3mil. Through precise circuit forming processes, it ensures low loss and low interference in high-frequency signal transmission, matching the high-speed, high-capacity transmission requirements of satellite communication.
Stringent Quality Control: Ensuring Stable Performance Throughout the Flow High-multilayer PCBs for satellite communication have extremely high requirements for performance consistency and reliability. Quality control is implemented throughout the entire production process. A comprehensive ISO9001 quality control system is established, strictly adhering to IPC standards and industry specifications. Multiple inspections and controls are conducted on incoming raw materials, process manufacturing, and finished product delivery to ensure that every PCB with 20 or more layers at the backplane level meets satellite communication application standards. A PDCA cycle process is implemented for quality, continuously optimizing processing parameters and improving process details to enhance product performance stability and adapt to the long lifespan and high reliability requirements of satellite communication equipment. Equipped with professional testing equipment such as impedance testers and gold-nickel thickness testers, we accurately test key indicators of multilayer PCBs, including impedance accuracy, plating thickness, and dielectric properties, ensuring high-frequency signal transmission performance meets standards and is free of performance deviations, thus guaranteeing high fidelity and stability of satellite communication system signal transmission.
