Manufacturing Difficulties of Aluminum PCB

The manufacturing process for nearly all aluminum PCBs is essentially the same. Here we will discuss the major manufacturing processes, the difficulties and their solutions.

 

1.Copper Etching: the copper foil used in Aluminum PCBs is comparatively thicker. If the copper foil is over 3oz however, the etching requires width compensation. If it is not according to the demand of the design, the trace width will be out of tolerance after etching. Therefore the trace width compensation should be designed accurately. The etching factors need to be controlled during manufacturing process.

 

2.Solder Mask Printing: due to the thick copper foil there is a difficulty in solder mask printing of aluminum PCB. This is because if the trace copper is too thick then the image etched will have a large difference between trace surface and base board and solder mask printing will be difficult. Therefore, the two-time solder mask printing is used. The solder mask oil used should be of good quality and in some cases the resin filling is done first and then solder mask.

 

3.Mechanical Manufacturing: the mechanical manufacturing process involves mechanical drilling, molding and v-scoring etc. which Is left on internal via. This tends to reduce electrical strength. Therefore, the electric milling and professional milling cutter should be utilized for low-volume manufacturing of products. The drilling parameters should be adjusted to prevent burr from generating. This will help your mechanical manufacturing.

Aluminum PCB is one of the most widely used metal core PCBs, also called as MC PCB, aluminum-clad, or insulated metal substrate, etc.

 

Usually, aluminum PCB includes four layers: a substrate layer (aluminum layer), a dielectric layer (insulating layer), a circuit layer (copper foil layer), and an aluminum base membrane (protective layer).

WHAT IS AN ALUMINUM PCB?

A PCB generally consists of three layers. A conductive copper layer at the top, a dielectric layer in between, and a layer of a substrate at the bottom. Standard PCBs have a substrate layer made of fiberglass, ceramic, polymers, or any other non-metal core. An ample amount of PCBs uses FR-4 as the substrate.

Aluminum PCBs use an Aluminum substrate. Instead of standard FR-4 as the substrate material.

Circuit Copper Layer

This layer transmits signals over the entire PCB board.

The movement of charged particles generates heat.

This heat is transferred to the Aluminum substrate. Which dissipates it efficiently.

Insulating Layer

This layer is also known as the dielectric layer.

It is made of materials that are poor conductors of electricity.

It absorbs the heat generated in the above layer. And transfer it to the Aluminum substrate below it.

Substrate

The substrate acts as a foundation for the PCB.

It firmly holds the components above it. By changing the characteristics of the substrate, the performance of PCB varies.

For example, a rigid substrate provides strength and durability to the PCB board.

While a flexible substrate opens up more design options.

 

The aluminum substrate is used in power electronics-based applications where high thermal dissipation is required.

Due to its good thermal conductivity, it keeps heat away from vital electronic components. Thus ensuring minimal circuit damage.

It dissipates heat in a highly efficient manner. For high power and tight tolerance based applications Aluminum Backed PCB is the perfect choice among project makers.

Considering parameters like the coefficient of thermal expansion, thermal conductivity, strength, hardness, weight, and cost. Aluminum plate is an ideal choice for your project. You can modify your PCB substrate. PCBWay offers different Aluminum plates like 6061, 5052, 1060, and many more.

ADVANTAGES OF ALUMINUM PCB

1. The heat dissipation capacity of Aluminum PCBs is far better than standard PCBs.

2. Aluminum PCBs provide more strength and durability. As compared to ceramic and fiberglass-based PCBs.

3. It seems ironic, but aluminum-based PCBs are lighter. As compared to standard PCBs.

4. Thermal expansion and contraction of PCB components get reduce by using Aluminum PCB.

5. PCBs made of Aluminum are environmentally friendly. It is non-toxic and recyclable. It does not create any harmful impacts on our planet.

6. The assembling process of Aluminum PCB is easy than that of standard PCB.
