Description
What is the super heavy copper or super thick copper board?
Meidear pcb suppling to you!
Designed For Extreme Current Handling And Heat Dissipation
This super heavy copper PCB is developed for high-load electrical environments where traditional copper thickness fails to meet performance or safety requirements. The 10oz copper layers allow for significant current-carrying capability, low resistance, and robust thermal performance. It is engineered for engineers, energy system integrators, and control cabinet manufacturers who need reinforced board structures in demanding power conditions. Recognized by industrial pcb suppliers, this board is also valued for its long-term durability in intensive applications supported by advanced pcb services.
Copper Weight And Multi-Layer Configuration
The core characteristic of this board is its 10oz (approximately 350μm) copper thickness, supported across multiple layers to ensure uniform heat dissipation and current flow. The base material is high-Tg FR4, which provides enhanced mechanical strength and temperature resistance. Vias are plated to withstand the electro-thermal stress caused by high current surges. Layer stack-up is customizable, and board finishes like ENIG and HASL are available. These parameters allow the board to integrate with flexible circuit board systems when hybrid power modules are involved, making it relevant to both pcb manufacturer and flex pcb applications.
Applications In Power Distribution, Control, And Conversion
This PCB is frequently implemented in converters, high-power rectifiers, electric vehicle power modules, and renewable energy systems. Its ability to deliver stable voltage under load and manage thermal feedback makes it ideal for rugged field environments. Designers of power pcb systems for industrial motors, HVAC controllers, and off-grid solar inverters rely on such boards for performance consistency. It is an established choice for OEMs sourcing from global pcb suppliers with requirements for specialized pcb services.
Product Advantages
High Copper Weight Enables Enhanced Current Density
With 10oz copper layers, this board supports extremely high current without overheating or trace degradation. Compared to standard boards, its capacity to distribute power over wide traces makes it suitable for demanding electrical routes and power bus networks. Thermal efficiency improves as the copper itself acts as a heat spreader, reducing dependency on external heat sinks. It’s frequently selected by pcb manufacturer partners working on scalable power pcb designs for infrastructure and heavy-duty applications.
Thermal Expansion Stability With High-Tg FR4 Base
Thermal cycling in high-power systems causes board deformation and delamination if the substrate is not adequately selected. This board uses high-Tg FR4, allowing it to operate consistently under elevated temperatures. The copper-to-substrate adhesion is reinforced through controlled lamination processes, supporting dimensional stability and protecting the plated through-holes. This becomes crucial when integrating with flexible pcb assemblies in modular systems, where alignment and heat resistance matter for both pcb services and device reliability.
Reinforced Layer Bonding For Structural Integrity
Super heavy copper layers can impose mechanical stress during handling or during high-current operation. This board’s manufacturing process includes reinforced layer bonding using high-pressure pressing and full-depth resin fill to prevent separation or blistering. Edge routing remains clean even in multi-panel configurations. These factors contribute to longer product lifespans in mission-critical circut board installations and make the product suitable for integration into hybrid flex pcb systems where mechanical reliability is essential.
Use Scenarios
Power Equipment Engineers Building Inverter Control Boards
Engineers developing inverter circuits for industrial motors, HVAC, or generator units need PCBs that can support repetitive current spikes and temperature cycling. This super heavy copper board withstands high DC and AC loads without degrading trace integrity. Used in standalone control cabinets and embedded units, it is sourced from reliable pcb suppliers that offer customized pcb services including hole plating and thermal simulation data.
Renewable Energy Developers Integrating Battery Management Systems
For off-grid or hybrid power systems, battery management units and DC-DC converters demand PCBs that can handle high amperage with minimal loss. This 10oz power pcb offers low internal resistance and ensures consistent voltage delivery under full-load operation. Developers in solar storage or wind-powered systems collaborate with pcb manufacturer teams to specify trace paths and via reinforcement for energy-dense modules that may also include flexible circuit board interconnects.
Automotive Design Consultants Specifying Electric Drive Controllers
In electric vehicle subsystems such as drive units or onboard chargers, thermal regulation and structural integrity are core to PCB selection. Consultants working on powertrain integration specify these super heavy copper boards for their high thermal mass and layered power routing. The board’s reliability in temperature swings and vibrational loads makes it a dependable choice when designing high-capacity led pcb or hybrid flex pcb configurations for mobile use.
