16-Layer Heavy Copper PCB Stackup

The stackup is engineered for optimal signal integrity, power plane decoupling, and mechanical symmetry to prevent warpage. The uniform3oz copper cladding is a defining feature across all conductive layers.

Core Material: S1000-2M TG180 High-Performance Laminate

The foundation of this PCB is the Shengyi S1000-2M material, a multi-functional epoxy resin system reinforced with glass fabric. This material is specifically formulated for high-layer-count and high-reliability applications.

Key Features of S1000-2M Material: 

• Superior Thermo-Mechanical Reliability: Its lower Z-axis Coefficient of Thermal Expansion (CTE) minimizes stress on plated through-holes during thermal cycling, ensuring excellent through-hole reliability and preventing barrel cracking.
• Exceptional Environmental Resistance: Demonstrates excellent Pressure Cooker Test (PCT) performance and low water absorption, leading to high resistance to heat, humidity, and long-term exposure to harsh conditions.
• Enhanced Processibility & Lead-Free Compatibility: Offers excellent mechanical processibility (drilling, routing) and high thermal resistance, making it fully compatible with demanding lead-free (RoHS) assembly processes that involve higher reflow temperatures.

• Automotive Electronics: Under-the-hood control units, power inverters for EVs, and ADAS systems.
• Industrial & Power Electronics: Motor drives, UPS systems, and power converters.

The Advantage of Heavy Copper Construction

What is Heavy Copper?

Traditionally, PCBs use 1oz (35µm) or 2oz (70µm) copper. Heavy Copper technically refers to copper weights of 3oz (105µm) and above per square foot. This board utilizes a significant 3oz weight on every layer.

Functions and Benefits:

1) High Current Carrying Capacity: The primary function. Cross-sectional area increases linearly with copper weight, drastically reducing trace resistance. This allows the board to conduct tens or hundreds of amperes without overheating or excessive voltage drop.

2) Enhanced Thermal Management: The thick copper layers act as an embedded heat spreader, conducting heat away from hot components (like MOSFETs, regulators) and distributing it across the board, reducing hotspot temperatures and improving system reliability.

3) Increased Mechanical Strength: Heavy copper adds structural rigidity to the PCB, particularly at connector points and in through-hole pads, increasing durability in high-vibration environments.

4) Space Efficiency: Instead of using wide, thin traces or external bus bars for high-power paths, heavy copper allows for more compact, efficient routing of power traces, saving valuable board space.

Application Domains for Heavy Copper PCBs:

• Power Conversion & Distribution
• Automotive & Electric Vehicles
• Renewable Energy
• Industrial Equipment
• Aerospace & Defense

Conclusion

The 16-layer Heavy Copper PCB is not a standard circuit board; it is a robust electromechanical platform. By marrying the exceptional stability and reliability of S1000-2M TG180 material with the formidable current and thermal performance of all-layer 3oz heavy copper, this product is engineered to empower the most demanding power-dense and reliability-critical electronic systems on the market today.
