From Idea To Product!
Explore our primary circuit board electrical designs engineered specifically to withstand elevated thermal thresholds and high-current demands in modern power architectures.
The global shift toward decarbonization has accelerated the demand for high-reliability circuit board electrical systems. In the domains of new energy—including electric vehicles (EVs), photovoltaic solar systems, wind power generation, and energy storage systems (ESS)—power electronics serve as the vital bridge converting, controlling, and distributing electrical energy. Unlike traditional consumer electronics, circuit boards designed for new energy must operate under extreme thermal conditions, manage high voltages up to 1500V and beyond, and sustain high currents without degradation.
Industrially, the market is moving rapidly from standard FR4 materials to advanced substrates such as heavy copper PCBs, metal-clad substrates (MCPCBs), and ceramic-based boards. These technologies are crucial to ensuring that power converters, inverters, and battery management units run efficiently. High power density requires minimize parasitic inductance and optimize heat dissipation. As wide-bandgap (WBG) semiconductors like Silicon Carbide (SiC) and Gallium Nitride (GaN) become the standard, PCBs must evolve to handle higher switching speeds and elevated operating temperatures, reshaping the supply chain and manufacturing requirements worldwide.
From grid-level storage to compact automotive control modules, modern power electronics require specialized PCB layouts that optimize electrical integrity and thermal pathways.
BMS platforms require high-accuracy voltage monitoring, cell balancing, and temperature regulation. Flexible and rigid-flex PCBs are widely integrated within battery modules to replace bulky wire harnesses. This reduces overall weight, enhances space utilization, and mitigates risks associated with vibrations in electric vehicles. The integration of robust circuit board electrical connections ensures safe, continuous data acquisition across thousands of individual battery cells.
The traction inverter converts DC power from the battery to AC power for the electric motor. This process generates substantial heat and demands circuit boards that can accommodate heavy copper layers (often exceeding 4oz to 10oz) to carry currents upwards of several hundred amperes. Advanced dielectric layers and thermal vias are utilized to transfer heat directly to liquid-cooling plates, maintaining component temperatures within safe operational thresholds.
Photovoltaic systems rely on central or string inverters to convert DC solar energy into grid-compatible AC power. These installations operate outdoors and are subjected to extreme environmental stresses. PCBs used here feature high-tracking index (CTI) laminates and thick conformal coatings to prevent electrical tracking and moisture ingress, ensuring a operational lifespan of 20 to 25 years.
High-power charging stations (up to 350 kW and beyond) require robust power distribution units and control electronics. The circuit board electrical layout must handle rapid voltage transitions and high thermal loads. Designers implement mixed-technology PCBs that combine low-voltage control circuits with high-voltage power paths on a single substrate, requiring precise isolation distances (creepage and clearance) to meet strict safety standards.

As power densities continue to rise, traditional design methodologies are reaching their physical limits. The industry is actively adopting several breakthrough technologies to keep pace with the demands of next-generation power electronics:
Traditional PCBs typically utilize copper weights of 1oz to 2oz. In high-power applications, heavy copper boards (3oz to 15oz or more) are required. These thick copper traces act as structural conductors that can handle massive electrical currents while simultaneously acting as high-efficiency heat sinks, reducing the need for external busbars and heavy wiring harnesses.
To reduce parasitic inductance and optimize space, manufacturers are embedding passive components, and even active power dies, directly within the internal layers of the PCB. This shortens the electrical pathways, which is critical for the ultra-fast switching frequencies enabled by SiC and GaN transistors.
Effective heat dissipation is paramount in power electronics. Modern board designs utilize direct thermal path (DTP) technology and insulated metal substrates (IMS) with thermal conductivities reaching 3 W/m-K to 10 W/m-K. These materials ensure rapid heat transfer from critical switching components to external cooling systems, preventing thermal runaway and extending system lifespan.
For high-power applications, the choice of surface finish directly impacts connection reliability. Electroless Nickel Immersion Gold (ENIG), Immersion Tin, and Organic Solderability Preservatives (OSP) are selected based on assembly requirements. OSP, for instance, provides an ultra-flat surface profile ideal for fine-pitch SMT components while offering excellent short-term oxidation protection during storage.
