Aluminum PCB FAQ for LED Lighting Mass Production

To prepare an accurate quotation, we require Gerber files, order quantity, board thickness, copper thickness, surface finish, and any special processing requirements.

Yes. Samples can be produced before mass production so specifications and process requirements can be confirmed in advance.

Common board thickness options include 0.6 mm, 0.7 mm, 0.8 mm, 1.0 mm, 1.4 mm, and 1.5 mm.

Standard copper thickness options include 12 um, 18 um, 25 um, and 35 um. The suitable option depends on the application and design requirements.

For many standard LED lighting boards, yes. 1oz copper is usually enough for common 1A-3A LED driver currents when trace width is selected with enough production margin.

Only slightly. The aluminum base helps spread heat, but the dielectric layer limits heat transfer from the copper trace into the metal core. Do not reduce trace width dramatically only because the board uses aluminum.

Use 2oz copper when current is above 3A, when traces are long, or when voltage drop and temperature rise need more margin. For many standard LED boards, 1oz copper is still the default choice.

Usually yes with 1oz copper, but the final choice depends on allowed temperature rise, trace length, copper thickness, copper pours, ambient temperature, and manufacturing tolerance.

No. Trace current is mainly set by copper cross-section and allowed temperature rise. Aluminum base thickness can help heat spreading, but it does not replace proper trace width design.

Common surface finish options include OSP and HASL.

The standard thermal conductivity is 1 W/mK. If your project has specific thermal requirements, we can review them based on the application.

Lead time depends on order quantity and production scheduling. Sample and mass production schedules are confirmed before order so delivery planning remains predictable.

Yes. This product is mainly designed for LED lighting and other thermal-management applications that require practical, stable specifications.

OSP PCBs are commonly managed around 3-6 months under proper sealed storage. Actual usable time depends on packaging, temperature, humidity, handling, and solderability condition before assembly.

A practical target is 24-48 hours after opening. If the boards cannot be assembled soon, keep them in a dry cabinet or controlled environment and mark the opening date.

Finished OSP-coated boards should not be baked as a solderability recovery method. Heat can damage the organic coating, so uncertain storage condition should be checked with solderability testing instead.

No. OSP oxidation does not directly reduce the thermal conductivity of the aluminum base or dielectric layer. The main concern is solder joint quality and interface resistance between the LED and the board.

Sometimes. If the boards were stored well and still pass solderability testing, they may be acceptable for assembly. If pads are oxidized, contaminated, or fail wetting checks, do not use them directly for mass production.

In some cases, yes. Reconditioning usually requires a qualified PCB fabricator to clean, micro-etch, recoat, and repackage the boards. Badly damaged or severely oxidized boards may be better scrapped and remade.

OSP is better when cost control is important and boards will be assembled soon. HASL is often more practical when storage time is longer or assembly timing is uncertain.

Yes. SMT assembly and turnkey PCB assembly support are available for suitable projects.
