Aluminum PCB Classification

Depending on the type of application and dielectric layer material, aluminum PCBs can be divided into three categories:

• General Purpose Aluminum PCB - The dielectric layer consists of epoxy fiberglass prepreg.

• High Thermal Conductivity Aluminum PCB - The dielectric layer is composed of epoxy resins other types of resins with high thermal conductivity.

• High Frequency and Microwave Aluminum PCB - The dielectric layer consists of polyolefin resin or polyimide resin glass fiber prepreg.

Manufacturing Difficulties of Aluminum PCBs and Solutions

Whether it is a single-layer, double-layer or multi-layer aluminum PCB, or MCPCB, they have many similarities in the manufacturing process of FR4 PCB. Nonetheless, aluminum PCB, as an advanced PCB, still has special aspects of the manufacturing process that require strict and effective management and control.

• Thick copper foil etching

Aluminum PCBs are usually used in power devices with high power density, so the copper foil is relatively thick. Copper etch requires trace width compensation when the copper foil thickness is 3 oz or more. Otherwise, the trace width will be out of tolerance after etching. Therefore, in order to guarantee the best trace width/spacing and impedance control to meet the design requirements, the following must be done in advance. Trace width compensation should be properly designed.

b. The effect of trace fabrication on trace width/spacing should be eliminated.

c. Etching factors and reagent parameters should be strictly controlled.

• Solder mask printing

Solder mask printing is seen as a manufacturing challenge. Due to the effect of thick copper foil, aluminum PCB manufacturing will have a large difference between the trace surface and the substrate if the trace copper thickness is abnormal after image etching, and the solder mask will become difficult. To ensure smooth solder mask printing, the following guidelines should be followed:

a. Soldermask should be obtained with high quality properties.

b. Use two solder mask prints.

c. When necessary, first rely on resin filling and solder mask manufacturing methods.

•Machine made

Mechanically fabricated aluminum PCBs contain mechanical drilling, milling, and molding, and V-nicks and burrs tend to remain on internal vias, which will reduce electrical strength. Therefore, in order to ensure high-quality machine manufacturing, the following principles should be followed:

a. Electric milling and professional milling cutters should be used for small batch production.

b. Attention should be paid to control techniques and patterns during the mold forming process.

c. Drilling parameters should be properly adjusted on thick copper-aluminum PCBs to prevent burrs.

LED PCBs are metal core PCBs, which use metal as the base material, such as aluminum, iron or copper. In most cases, the LED PCB is an aluminum PCB. Aluminum is mainly used to make LED light Aluminum PCB Board PCBs because it is cheap and lightweight compared to other metals.

Led Aluminum PCB Board consists of three layers. These layers are copper layers, dielectric layers and aluminum base layers. The topmost layer is the copper layer, which makes the electrical connections in the PCB. This layer is standard in all types of PCBs. To protect this layer, a surface treatment is used. Copper provides excellent electrical conductivity and completes the circuit.

The next layer is the dielectric layer, which is very important in metal core PCBs. This dielectric layer acts as an insulator and prevents current flow in the base aluminum layer. This layer has excellent thermal conductivity, which is conducive to heat dissipation.

The last layer of the PCB is the base layer, which is made of aluminum. This layer makes the board unique and gives it a separate identity. Due to the base layer, the PCB is more durable than FR-4. It can withstand wear and high temperatures. In addition, its cooling effect is excellent. It is lighter than copper and iron.
