From solar inverters and EV charging stations to energy storage systems and smart grid infrastructure — high-current, thermally robust PCBs engineered for outdoor, 24/7 power applications.
The shift to renewable energy and EV transport demands high-current, thermally robust boards that last decades outdoors.
High-frequency RF boards on Rogers laminates for 77 GHz forward collision, lane departure and autonomous driving sensor fusion.
Heavy copper BMS boards for cell monitoring, thermal management and charge control in hybrid and full-electric vehicles.
High-temperature multilayer boards for ECU and TCU operating near the engine bay from -40°C to +150°C.
HDI multilayer boards for in-vehicle displays, connectivity, navigation and digital cluster platforms.
IPC Class 3 boards for ABS, ESP, airbag control and active suspension — zero tolerance for in-field failure.
Standard multilayer PCBs for door locks, window controls, lighting automation and central body electronics.
Metal-core and aluminium PCBs for matrix LED headlights and adaptive lighting systems.
Robust multilayer PCBs for climate control, seat adjustment and ambient environment management.
Power electronics boards carry hundreds of amperes, dissipate kilowatts and operate outdoors for 20+ years. Standard PCB manufacturing is simply not suitable.
A 100 kW solar inverter board may carry 400+ A on a single bus trace. Standard 1 oz copper fails within months under these conditions. Heavy copper up to 20 oz, custom thermal via arrays and embedded copper coin cooling are the only reliable solutions.
up to 20 oz copper · thermal vias · 400A+ busEnergy infrastructure boards operate outdoors, in direct sun, humidity, salt air and extreme temperature cycles for two decades. PCB laminates, surface finishes and solder mask must be specified for IEC 62109 and IEC 61730 compliance with no in-service degradation.
IEC 62109 · -40°C to +125°C · UV-resistant coatingGrid-tied inverters and EV chargers operate at 400 V to 1500 V DC. PCB design must comply with IEC 60664 clearance and creepage requirements — board thickness, slot routing and surface finish choices directly affect isolation performance.
1500V DC · IEC 60664 clearance · slot routingPower electronics demands board technologies that go beyond standard manufacturing.
Up to 20 oz finished copper for high-current bus bars, power distribution and motor drive boards. Custom thermal via patterns, asymmetric copper distribution and bus-bar integration — all in-house, no outsourcing of critical copper processes.
Aluminium and copper-base MCPCBs with thermal conductivity from 1.0 to 5.0 W/m·K for LED power modules, IGBT cooling and power converter thermal management. Custom base thickness and anodised finish options.
High-Tg FR4 and polyimide multilayer boards for battery management systems, grid control units and precision energy metering — rated for -40°C to +125°C with 20-year design life and full lot traceability.

Solar farms and EV charging networks operate for 20+ years. Board failures in the field are expensive to access and replace. Our DFM review, current-carrying capacity verification and thermal analysis prevent field failures before they happen.
Real automotive PCB challenges — and how we solved them.
16-layer heavy copper (8 oz) board for a 50 kW three-phase string inverter. 400 A bus bars, custom thermal via array, IEC 62109-1 isolation compliance and outdoor UV-resistant finish.
Zero thermal-related failures across 8 years of deployment at 3,000+ installation sites. Thermal resistance 18% below target spec, allowing customer to reduce heatsink mass.
20-layer heavy copper board for a 150 kW CCS/CHAdeMO DC fast charger power module. 600 A bus bars, bi-directional capability, IEC 61851 compliance and IP67 sealing-compatible stackup.
All IEC 61851 and UL 2202 compliance tests passed at first submission. Charger boards have operated at motorway sites through 3 winters with zero environmental ingress failures.
12-layer IPC Class 2 board for a 1 MWh grid-scale battery energy storage BMS. Full lot traceability, IEC 62619 safety compliance documentation and thermal cycling qualification.
BMS boards qualified for 15-year design life. Customer's storage system achieved 99.4% availability over first 2 years of grid operation — above contracted SLA level.
Automotive procurement teams need more than a PCB factory — they need a certified partner with documented processes, fast engineering response and the depth to solve problems before the production line.
We press, plate and etch copper up to 20 oz entirely within our facilities. Your bus bar current ratings are controlled by our engineers, not subcontracted to a job shop with unknown processes.
Our power electronics engineers check your copper distribution, thermal via design, isolation clearances and IEC compliance within 8 hours — preventing failures before a single board is made.
We verify current-carrying capacity against IPC-2152 on every heavy copper lot. Your board will handle its rated current continuously, not just at datasheet conditions.
Solar farms and charging networks are installed worldwide. We deliver DDP to project sites in Europe, Americas and Asia-Pacific, with all RoHS and REACH documentation for local compliance.
Our energy and power PCB engineering team will review your design and return a full DFM report and quote within 8 working hours.
