Drilling and Routing

The next step is drilling and routing the PCB. Holes are drilled in the aluminium layer to allow for component placement and electrical connections. The size and placement of the holes are determined by the PCB design. The PCB is then routed to remove any excess aluminium and create the desired shape.

Copper Cladding

After drilling and routing, a layer of copper is applied to the aluminium layer. This copper layer is used to create the electrical connections between the components. The thickness of the copper layer can vary depending on the application and the desired electrical performance.

Solder Mask

Once the copper layer is applied, a solder mask is added to protect the copper layer from oxidation and to prevent short circuits. The solder mask is a layer of polymer that is applied to the surface of the PCB. The solder mask is usually green, but can be any color depending on the desired look and feel of the PCB.

Silkscreen

Finally, a silkscreen layer is added to the PCB. The silkscreen layer is used to add text and graphics to the PCB, such as component labels and logos. The silkscreen layer is usually white, but can be any color depending on the desired look and feel of the PCB.

In conclusion, the manufacturing process for aluminium LED PCB boards involves selecting the right materials, drilling and routing the PCB, adding a copper layer, applying a solder mask, and adding a silkscreen layer. The process is complex and requires a high level of technical expertise.
