Single-Layer Aluminum PCB for Automotive LED Lighting

This single-layer aluminum PCB is specified for automotive LED lighting. It uses Bergquist 3.0 aluminum material, 1 oz copper, a 1.6 mm board thickness, white solder mask, lead-free HASL, and stated thermal conductivity of 1.0 W. The product is intended for a simple LED circuit where a metal-backed board fits the electrical and mechanical design.

The board works best when the LED package, copper pattern, fixing points, and housing interface are already known. Automotive lighting assemblies often have tight limits around reflectors, lenses, connectors, and mounting hardware. The PCB outline and component placement need to follow those constraints from the beginning of the layout.

Product Overview

The single-layer construction suits an LED routing pattern that can be completed without crossovers or multilayer connections. One copper layer keeps the structure direct, but it also means the pad order and connector position need to support a clean route. If the circuit cannot be completed on one layer, a different board structure should be considered before the mechanical design is finalized.

The 1.6 mm profile needs to fit the intended housing or light assembly. When the board mounts against a heat sink, bracket, reflector, or metal frame, include the mating-surface drawing and fixing method with the RFQ. Screw locations, slots, edge clearances, and connector access can affect the finished outline just as much as the LED circuit does.

Material and Thermal Interface

Bergquist 3.0 aluminum material and stated thermal conductivity of 1.0 W are part of this product specification. The value should not be used as a general claim for every aluminum PCB. Projects with a different power level, dielectric requirement, or heat-transfer target need their own material and stack information.

The completed thermal path includes more than the bare board. LED package selection, solder joint, board mounting, interface material, and housing design all influence the installed result. Providing the light-module drawing gives the quotation useful context without turning the PCB page into a thermal-system guarantee.

LED Pad and Finish Details

Lead-free HASL is specified for the exposed pads. Pad size, solder-mask opening, and component orientation need to match the selected LED package and soldering process. White solder mask is part of the defined construction and should remain in the fabrication data. Polarity marks and reference text need enough room around pads, mounting holes, and optical areas.

If the board will be supplied with LEDs, connectors, or other components, send the BOM, placement data, and assembly drawing with the PCB files. The turnkey PCB assembly page provides related information for combined fabrication and assembly work.

Automotive LED Applications

This product is specified for automotive use and is suited to a defined LED lighting module rather than a generic vehicle-electronics claim. The RFQ should identify the light assembly, board outline, connector interface, quantity, and any inspection or documentation requirement relevant to the project.

Where several board shapes or LED variants share one vehicle platform, identify each outline and component option separately. This keeps the material specification consistent while allowing the quotation to reflect the actual drilling, routing, and assembly data for every version.

For a quotation, provide Gerber files, drill files, the LED layout, and the mechanical outline. Include the Bergquist 3.0 requirement, lead-free HASL pad details, mounting information, and application. Related fabrication options are listed under PCB manufacturing capabilities.
