Introduction:

Aluminum PCBs are the perfect solution if you're designing high-current / high-temperature circuits where heat dissipation is a major concern. So if your next project is a hybrid guitar amp to blow the roof off of the garage, or a badass laser rifle (check your local laws, kids!) to fend of extraterrestrial invaders, or even a high-power compact motor driver or LED floodlight (if, for some reason, you're committed to practical applications), seriously consider choosing aluminum as your PCB substrate. FR4 is great, but Aluminum is the way to go when the heat is on and you want to keep things cool.

Diagram of Aluminum PCB:

Aluminum PCBs produced by us are most commonly and widely used for LED lighting, power equipment and automotive systems. The following table presents some of our Aluminum Core materials:

Aluminum Core PCB for LED application

Aluminum is superior in heat conduction, corrosion resistance, lightweight and cost.

Getting started with LED Aluminium PCB Prototyping

The easiest and fastest way to get 1 layer 10 to 1000pcs Aluminium PCBs prototype for an incredible low price while the production and quality control follows all industrial standards.

How it works:

Kindly choose the available options as shown above and send your PCB Gerber files that complies with all the limitations. You can upload the Gerber files after verifying the credentials. After this is done, simply just click “add to cart” and you’re good to go.

For bigger quantities, special options, tests, panels, discounts or combination with our other services, kindly contact us directly at pcb@smart-prototyping.com.

Combinations

If you want more than only a naked PCB, you can combine the PCB prototyping service together with our other electrical prototyping services into a turnkey solution:

Solder Paste Stencil

The solder paste stencil is a Laser-cut steel on aluminum frame with a minimum recommended pitch of 0.4mm. Please make sure the effective area is twice as big as your PCB so that top and bottom side can be placed on the same stencil.

Effective AreaTotal SizePrice

19.0 x 29.0 cm37.0 x 47.0 cm$20
24.0 x 34.0 cm42.0 x 52.0 cm$28
37.0 x 47.0 cm55.0 x 65.0 cm$44
27.0 x 37.0 cm45.0 x 55.0 cm$36
40.0 x 40.0 cm58.4 x 58.4 cm$44


Separated Sub-Boards

For separating boards please use a slot according to following pictures. Drilling holes or other methods for separating boards will be NOT accepted. Boards which are separated only by silk-screen are not counted as sub-boards and don't have to be paid extra. Junctions between V-Slots are always crossing (X). For other junctions like (T) or (L) you need to use the normal milling and not the V-Slot.

Note

Please take note that we’re not responsible for your Gerber files and we are using them as-they-are for producing the PCBs. Customers are advised to make sure that the Gerber file complies with all limitations as according to our standards.
