Switch-mode power supply, AC-DC and DC-DC converter boards
Power Electronics PCB & PCBA Manufacturer
PCBArise manufactures power PCB and power supply PCB/PCBA for power supplies, inverter PCBs and motor-drive stages, IGBT/MOSFET modules, UPS, welding equipment, LED drivers and high-current industrial systems. Buyers start with current, voltage, thermal interface and assembly mass; those product requirements determine whether the board uses heavy copper, metal core, ceramic or a mixed power-and-control construction.

Power Supply, Inverter & Motor-Drive PCB Applications
Power electronics buyers search for a board partner around the power stage they are releasing. We connect the application—power supply, inverter, motor drive, IGBT, LED or UPS—to the PCB construction, assembly method and test access.
Inverter, motor-drive and variable-frequency-drive power stages
IGBT, MOSFET, gate-driver and isolated power-interface assemblies
Industrial rectifier, UPS, battery charger and power-distribution boards
High-power LED lighting and metal-core thermal boards
Welding, induction-heating, servo and high-current machine-control electronics
Busbar-style power interfaces and mixed power/control backplanes

What Power Electronics PCB Buyers Need to Decide
A power electronics PCB supplier must understand the complete power path, not only the routed artwork. Current, voltage, switching frequency, heat flow, isolation and component mass all affect the manufacturable product.
Continuous current and temperature rise: copper weight, plane width and connector rating are sized for the real load
Thermal path: chassis contact, heat spreader, thermal vias, aluminum or ceramic substrate and component placement work together
High-voltage isolation: creepage, clearance, slotting, coating and cleanliness belong in the product review
Mixed geometry: heavy-copper power planes sit beside fine-line gate-drive, sensing and communication circuitry
Power cycling: plated-through holes, large solder joints and interfaces are checked against the service profile
Assembly mass: transformers, inductors, electrolytics, heatsinks and busbars determine soldering and fixture access
Heavy-Copper and Thick-Copper PCB for the Actual Power Path
The converter, inverter or motor-drive requirement sets copper and stackup. The standard production window covers 0.5–12 oz copper and 1–40 layers; engineering checks the current path, isolation areas and mixed control geometry before tooling.
Power density makes material, copper and assembly choices inseparable.
Power boards combine current-carrying geometry, thermal paths, high-mass components and control circuitry. The build route has to protect all of them together.
- Copper weight and heat spreading
- Thermal interface and substrate choice
- THT, selective solder and inspection access

Questions to resolve before release.
These answers outline the information engineering needs to confirm the right manufacturing path.
How much copper can a power PCB or thick copper PCB use?
The published reference covers 0.5–12 oz copper. Copper weight is selected against your current and allowable temperature rise. Note that heavy copper etches with a trapezoidal profile, so achievable trace width and spacing widen as copper weight increases — our engineers confirm the achievable geometry for your copper weight during project DFM review rather than assuming the standard 2.5/2.5 mil minimum applies.
What thermal conductivity can your aluminum PCB reach?
Aluminum PCB reaches thermal conductivity up to 3.0 W/m·K. For higher power density we also manufacture ceramic substrate. Which one is right depends on your junction temperature target and the mechanical interface to the chassis — send us the thermal requirement with your RFQ and engineering will come back with a recommendation.
How thick a board can you build and assemble?
Fabrication supports 0.1–10.0 mm board thickness, with 1.6 mm standard and a thickness tolerance of ±0.05 mm on advanced builds. The published PCBA assembly thickness and warpage envelope applies to the relevant assembly route and must be confirmed against board construction and process review.
Can you handle large power boards and tall components?
The PCBA capability reference publishes a 50 × 50 mm to 400 × 1200 mm assembly envelope and a 120 mm maximum component height for applicable process lines. Board support, tooling, clearance and the soldering route are confirmed during engineering review. Wave, selective and hand soldering are available for high-thermal-mass and odd-form joints.
Can you build a board with heavy copper power planes and fine-line control circuitry together?
Yes, and it is one of the more common reasons power boards fail DFM elsewhere. The constraint is copper balance and resin fill during lamination. We review copper balance, stackup, and prepreg selection before tooling and will propose a build that holds both the current requirement and the control-side geometry.
What is the lead time for a heavy copper power board?
For 4–6 layer multilayer PCB: 48–72 hours prototype, 4–6 days small batch, 8–10 days mass production. Heavier copper and metal core builds typically sit at the longer end of the range. All lead times are subject to final evaluation of production files, process complexity, and BOM availability.
