What is Aluminum PCB?

 

Aluminum PCB is the most common type of all Metal Core PCB (MCPCB) also known as IMS (Isolated Metal Substrate). Aluminum PCBs are the most common type – the base material consists of an aluminum core with standard FR4. It features a thermal clad layer that dissipates heat in a highly efficient manner while cooling components and increasing the overall performance of the products. Currently, We regard Aluminum PCB as the solution to high power and tight tolerance applications.

Advantage of Aluminum PCB

1.Environmentally Friendly: 

Aluminum is non-toxic and recyclable. Manufacturing with aluminum is also conducive to conserving energy due to its ease of assembly. For printed circuit board suppliers, using this metal helps maintain the health of our planet.

2.Heat dissipation: 

High temperatures can cause severe damage to electronics, so it is wise to use a material that can help dissipate heat. Aluminum can actually transfer heat away from vital components, thus minimizing the harmful effect it could have on the circuit board.

3.Higher durability: 

Aluminum provides strength and durability to a product that ceramic or fiberglass bases cannot. Aluminum is a sturdy base material that can reduce accidental breakage during manufacturing, handling, and everyday use.

4.Lightweight: 

For its incredible durability, aluminum is a surprisingly lightweight metal. Aluminum adds strength and resilience without adding any additional weight.

Aluminum PCB Production Challenges

Aluminum PCB is a kind of metal-based copper clad board with good heat dissipation function, mostly used in the production of LED lights. Here let us understand the aluminum PCB production process of the difficulty analysis and production specifications.

Aluminum PCB is often used in power devices, power density, so the copper foil is thicker. The etching process requires engineering design line width compensation if you use more than 3 ounces of copper foil.

Aluminum base surface in the PCB processing process in advance with a protective film to give protection; otherwise, some chemicals will leach aluminum base surface, resulting in damaged appearance.

The hardness of the milling cutter used in the production of glass fiber board is relatively small and the milling speed is fast; while the hardness of the milling cutter used in the production of aluminum PCB is large and the milling speed is at least two-thirds slower.

The production of glass fiber boards only needs to use the machine itself to dissipate heat, but the processing of aluminum PCBs must additionally add alcohol for the gong head heat.

Aluminum PCB manufacturers in the production of aluminum PCB process will have some difficulties. These difficulties are as follows.

1.The use of mechanical processing production of aluminum PCB, drilling holes in the hole edge does not allow burrs, otherwise it will affect the pressure resistance test. The aluminum PCB milling process is very difficult, and punching profiles require the use of advanced molds. After shape punching, the edges are required to be neat and burr-free without touching the solder resist layer on the board edge. Usually, using the manipulator die, hole punching from the line, shape punching from the aluminum surface, and punching shape after the board warpage should be less than 0.5%.

2.In the entire aluminum PCB production process, it is not allowed to rub the aluminum base surface by hand touch, or by a certain chemical that will produce surface discoloration or blackening, which is absolutely unacceptable. So the whole process does not touch, does not touch the aluminum base surface. This is one of the difficulties in the production of aluminum PCBs.

3.In the aluminum PCB over high-voltage test, communication power The board surface dirt, holes, and aluminum base edge burrs, line jagged or touching any point of the insulation layer will lead to high-voltage test fire, leakage, or breakdown. Results in voltage resistance test board delamination, blistering, and rejection are rejected.

Application of Aluminum PCB

Usually, Aluminum Board is used in Home lighting, urban and historical lighting, road signs, street lighting, avionics, railway, automotive and a new trend in the health market or therapy area.
Aluminum PCB (IMS) is used on all those activities mainly because of the LED application increasing years after years. Aluminum is used as a heat sink.

Now, Let’s take a look at the specific applications of Aluminum PCBs in the electronics industry.
