High Power PCB Assembly: Engineered for Extreme Electrical & Thermal Demands
Our high power PCB assembly services are tailored for applications requiring ultra-high current (1000A+) and voltage (1000V DC) handling, such as EV traction inverters, HVDC transmission systems, and laser diode drivers. By leveraging 2oz copper layers (industry-standard max: 6oz), we reduce DC resistance by 40%, enabling 98% efficiency in SiC MOSFET-based power modules.
Thermal Management Innovations
To dissipate 500W/cm²+ heat fluxes, we integrate 0.3mm ultra-thin vapor chambers directly into PCBs, cutting thermal resistance by 60% vs. traditional heatsinks. Paired with AlN ceramic-filled substrates (3W/m·K thermal conductivity), our designs maintain junction temperatures below 125°C in 1500W solar microinverters.
High-Voltage Safety & Compliance
All assemblies meet IEC 60664-1 creepage/clearance standards with 8mm+ isolation distances for 1000V systems. Double-sided conformal coating and slot isolation techniques ensure partial discharge (PD) levels <1pC at 10kV RMS, validated via Haefely PD detectors.
Scalable Production & Quality
With 100K+ annual capacity, we support 48-hour prototyping using ANSYS Icepak thermal simulations and Keysight Power Integrity tools. Our 6σ SPC-controlled etching maintains ±5μm line/space tolerances on 2oz copper, while hybrid 3D AOI + X-ray inspection detects 0.05mm solder voids at 99.98% accuracy.
