Aluminum PCB consists of three layers, which are the copper layer, dielectric layer, and aluminum base layer. There can be a fourth layer, which is known as the aluminum base membrane layer. The membrane layer protects the aluminum from scraping, scratches, and unwanted etching.
Copper Layer: At the top of the aluminum PCB, there is a copper layer, which creates the circuit. The layer is common in all types of PCBs, including FR-4. It offers the electrical connection and conductivity of current among the components.
Dielectric Layer: Aluminum can also conduct electricity; therefore, a dielectric material is used between the copper layer and the aluminum layer. This layer can be of different materials depending on the temperature range. Although this layer is electrically insulated, it can conduct heat efficiently. It has excellent thermal conductivity to hold the heat from the components to the aluminum layer.
Aluminum Base Layer: This is the most crucial layer of the PCB. It provides thermal conductivity, durability, and strength to the PCB. The layer is made of aluminum substrate. The substrate can be of different types, such as Aluminum 505, Aluminum 6061, etc. You can choose the perfect aluminum substrate according to your requirements.
Aluminum Base Membrane Layer: The aluminum base film is selective. It has a protective effect by protecting the aluminum surface from scratches and unnecessary corrosion. It has two types, namely less than 120 degrees or about 250 degrees (high-temperature resistance)

FAQ:
Q1: How about your supply capacity?
A: For PCB board, you need to prepare files of Gerber file,it should including RS274X,ODB++, DXF, PCB, PCBDOC etc formats.For PCBA(PCB with soldered components), except the file for PCB, you also need to prepare the BOM list (components list), Pick and Place file(txt format), real sample picture or 3D PDF version file etc.
Q2: How about the Shipping cost?
A: The shipping cost is determined by the destination, weight, packing size of the goods. Please let us know if you need us to quote you the shipping cost.
Q3: What are the main products of your PCB/PCBA services?
A: Industrial control, Automotive, Medical Equipment, Communication Electronics, Security Devices.
