As the automotive industry accelerates toward electrification, intelligence, and high integration, the demand for automotive-grade PCBs with long service life, stable electrical performance, and excellent thermal management has never been higher.
Guangdong Sayfu Multilayer Circuits Co., Ltd. is a professional China automotive PCB manufacturer, supplying high-reliability printed circuit boards for both traditional vehicles and New Energy Vehicles (NEVs).
Our PCBs are engineered to withstand heat, vibration, current load, and long-term operation under harsh automotive environments.
We actively support the supply chains of global automotive OEMs and Tier suppliers, including projects related to BMW, Mercedes-Benz, Audi, Tesla, as well as leading Chinese manufacturers such as BYD and Great Wall Motor.
Why Sayfu for Automotive Electronics?
We don’t just fabricate boards — we engineer reliability.
Automotive electronics demand more than standard PCB fabrication. At Sayfu, our manufacturing processes, material selection, and engineering controls are optimized for zero-defect expectations, long product life cycles, and mass-production stability.
Advanced Automotive Material Portfolio
We support a wide range of automotive-grade PCB materials and constructions, including:
- Metal Core PCBs (MCPCB)
- Aluminum-based
- Copper-based
- High-temperature laminates (TG170 / TG180+)
- Ceramic substrate PCBs
- High-frequency & high-speed laminates
- Multilayer, rigid-flex, and hybrid stackups
These materials are designed to perform reliably under high temperature, vibration, and thermal cycling conditions typical in automotive systems.
Unique Capability: Differential Copper Plating
Sayfu offers a Differential Copper Plating technology that is rarely available in standard PCB fabrication.
We can manufacture boards with extreme copper thickness variation, such as:
- 10 oz copper on Side A — for high-power distribution
- 1 oz copper on Side B — for signal control and logic circuits
This hybrid structure allows high-current power paths and sensitive signal routing to coexist on a single PCB, improving space utilization, thermal efficiency, and system integration—particularly valuable for automotive power converters and control modules.
Heavy Copper PCB Expertise
We specialize in heavy copper PCB fabrication for automotive and new energy applications, supporting:
- Thick copper designs for high-current circuits
- Stable plating and controlled etching
- Reliable performance in power electronics and BMS systems
