YC PCB supplies high thermal conductivity aluminum substrate boards for high-power LED modules, UFO high bay lights and thermal management electronics. Available support covers aluminum base selection, dielectric thermal performance, copper thickness, solder mask, surface finish, LED PCBA and order-specific testing.
High Thermal Aluminum PCB Details
This aluminum substrate route is intended for projects that need stronger heat transfer than standard FR4 or general aluminum PCB. Selection is based on LED power, board shape, dielectric thermal conductivity, copper thickness, fixture contact and assembly requirements.
For High-Power LEDs
Suitable for LED modules, UFO high bay lights, industrial lighting boards and compact lighting systems that require efficient heat transfer away from concentrated LED pads.
Thermal Route First
The aluminum base, dielectric layer, copper circuit, LED pad opening and fixture contact area work together as one thermal system and should match the product’s operating conditions.
PCB + LED PCBA
YC PCB provides bare-board manufacturing and optional LED assembly when complete BOM, placement data, polarity information and testing requirements are supplied.
What Buyers Should Check Before Quotation
Before quotation, provide the board outline, LED layout, thermal conductivity target, mounting interface, surface finish and assembly requirements so the manufacturing route and cost can be matched accurately.
Available for round, square, strip and custom outlines with specified LED positions, mounting holes, connector areas and fixture interfaces.
The construction combines the copper circuit, electrically insulating thermal dielectric and aluminum base to transfer heat toward the fixture or heat sink.
Pad openings, reflective solder mask, copper width and component clearance are controlled according to the LED package and assembly data.
Suitable for high bay, industrial, warehouse, outdoor and compact LED modules with application-specific thermal and mechanical requirements.
High Thermal Aluminum PCB Specifications

Thermal Path for High-Power LEDs
High thermal aluminum PCB is used when LED junction temperature, lumen stability and service life depend on efficient heat transfer from the LED pads through the dielectric layer to the aluminum base and fixture housing.
LED Heat Source
LED pad geometry, dense LED zones, copper width and solder mask clearance are matched to the heat concentration and current load.
Dielectric Layer
The dielectric layer provides electrical insulation while transferring heat from the copper circuit to the aluminum substrate.

Aluminum base thickness, flatness, board size and mounting contact directly affect heat spreading into the finished fixture.
Fixture Interface
Thermal interface material, screw positions, housing contact and surface flatness should match the board design to minimize thermal resistance.
The complete heat path runs from the LED pad through the copper circuit and dielectric layer into the aluminum base and fixture housing.
Material and Finish Options
YC PCB supports standard aluminum, high thermal aluminum, copper substrate and FR4 routes. Material and finish are selected according to heat load, solderability, reflectivity, weight, cost and production volume.
Surface finish and solder mask are selected according to the LED assembly process, storage period, pad design, optical requirements and required solderability.
| Route | When to Use | Buyer Review Point |
|---|---|---|
| Standard Aluminum PCB | Common LED lighting projects with moderate heat load | Cost, board shape and basic thermal performance |
| cURL Too many subrequests by single Worker invocation. To configure this limit, refer to https://developers.cloudflare.com/workers/wrangler/configuration/#limits | High LED density, higher power or tighter lifetime target | Thermal conductivity target and fixture heat sink |
| Copper Substrate PCB | Stronger thermal transfer demand | Cost, weight, machining and application necessity |
| PCB FR4 | Low-power lighting or control circuits | Not preferred for high-power LED heat loads |
Design Checks for High Thermal Aluminum PCB
Production files should define thermal transfer, current load, insulation, LED placement, board profile, surface finish and assembly requirements.
LED Pad and Mask Opening
Pad size, LED polarity, solder mask opening, reflective surface and clearance around high-temperature zones should match the component package and assembly process.
Copper Width and Current Load
Trace width, copper weight and current path should support the specified load while limiting voltage drop and localized heating.
Insulation and Safety
Dielectric insulation, creepage, clearance and base material should meet the product’s electrical and environmental requirements.
Board Outline and Mounting
Diameter, slots, mounting holes, CNC routing, V-cut and fixture alignment are manufactured from the approved mechanical drawing.
Connector and Driver Area
Connector and driver areas should be positioned to support assembly access and reduce exposure of heat-sensitive parts to concentrated LED heat.
PCBA and Testing Route
For assembled orders, provide BOM, LED bin, polarity, functional test method, labeling and packing requirements.
Manufacturing Flow
Production includes material preparation, circuit imaging, etching, solder mask, surface finish, outline processing, inspection and protected packing.
