What are the Features and Applications of 4 Oz PCB?

4 oz PCB is widely regarded as a heavy copper PCB. In the industry of electronics, the 4 oz PCB is highly demanded. This is so due to its uniqueness, as well as its use in different applications.

If you desire to know more about 4 oz pcb, as well as 4 oz copper thickness, then continue reading. With this article, you will have answers to whatever queries you may have, and have vast knowledge regarding the topic.

4 Oz PCB: What is this?

4 Oz PCB is a unique PCB that utilizes heavy copper. These circuits are of high density. This is why you don’t need to solder it from one point to the other.

4 Oz PCB density increases as a result of the extra layer that is usually found in printed circuit boards. In this particular layer, you will be able to add 4 Oz PCB components.

Furthermore, it is useful for many applications, most especially those requiring high-power current. It also serves electronics requiring higher technology. Normally, when expressing copper wire weight in the PCB industry, we do it in Oz (ounce). Therefore, for the 4 Oz PCB, the weight is 4 ounces.

Asides from their basic and simple structures, 4 Oz copper thickness is usually cost-effective. Furthermore, this PCB is spacious. This is why they are more flexible in contrast to ordinary PCBs.

4 Oz PCB is very unique. This is because you can use the two sides of the circuit board. This is why it is cost-effective.

4 Oz PCB Base Material

One very important part of printed circuit boards is the base material. This material affects the performance efficiency and functionality of PCBs. FR-4 at a temperature of 140°C is the 4 Oz PCB base material.

However, you may also utilize a material with a high transition temperature at 170°C. The base material selection has to do with the project you wish to work on. Also, it depends on the project’s complexity. With the base material’s variation, the 4 Oz copper thickness PCB materials will change.

All base materials come with their own unique properties. Comparing the materials FR4 and high Tg, you will discover that the properties of your 4 Oz PCB with each of the materials will be very different.

However, selecting your base material must always have to be based on what the client wants and the requirements he or she has set out.

What is the 4 Oz Copper Thickness?

To ensure your PCB works effectively, then you must pay good attention to the thickness. This thickness plays a vital role in the overall performance of your printed circuit board.

There must be a precision while manufacturing 4 Oz PCBs. This ensures that the thickness is accurate. 4 Oz PCB comes with a standard thickness, which is usually between 0.6mm and 0.65mm.

In the board’s configuration, there is an added component. Here, you will be able to add other components. Furthermore, the board’s size could also vary. This depends on the project’s requirement. The standard size of the board ranges from 6mm by 6mm to 467mm by 610mm.

Moreover, the board’s size and thickness depends on the project’s complexity. Both features are very important for its effective functioning. Furthermore, you can customize the thickness and the size of the PCB to suit your client’s requirements.

Applications of the 4 Oz PCB

4 Oz PCBs are unique PCBs that play a vital role in the electronics world. Because it is unique, they are useful in many applications.

First, the modern BARE PCB industry utilizes 4 Oz copper thickness in electronic devices requiring high technology. Also, you can apply 4 Oz PCB in welding equipment.

Power converters utilize 4 Oz PCB for their configurations. Asides from this, you can also find this PCB useful in space systems and radar systems of high technology.

Furthermore, 4oz copper PCB can be useful in the automobile and solar panel systems. It can also serve the electric or general power supply systems.

Different industries feature control panels. 4 Oz PCBs play a major role in industrial panel manufacturing. You will also find 4 Oz PCBs in vending machines, car dashboards, amplifier systems, and lighting systems.

4 Oz PCB Surface Finish

Surface finish has to do with a material’s coating, which is usually found in between a circuit board’s components. Applying this surface finish is necessary to ensure that the soldering of the board’s components is tight enough.

Another reason why the surface finish is important is that it protects the board’s copper circuit. Also, it protects this board from oxidation.

For the 4 Oz PCB, HASL – Hot Air Solder Leveling is the main surface finish. This finish includes a double layer of metallic coating coupled with nickel. Also, it is repairable and cost-effective.

Asides from HASL, ENIG surface immersion is also useful. ENIG means Electronic Nickel Immersion Gold. This gold layer helps in protecting the nickel layer.

Furthermore, you may use the lead-free type of HASL. All these surface finishes help in protecting your 4 Oz PCB from any damage.

What is the Strength of the 4 Oz Copper PCB Circuit Board?

The strength of your circuit board tells how strong your PCB is to resist electrical damages. The 4 Oz PCB’s strength has to do with the base material type.

This also has to do with the power board’s current-carrying capacity. Moreover, the voltage and resistance of this PCB affects the strength of the circuit board.

If the 4 Oz PCB sees a rise in heat resistance, it can cause the copper wires to crack up. You must ensure that these factors are maintained.

What Purpose Does 4 Oz PCB Serve?

The main purpose of PCBs with 4 Oz copper thickness is to support the different components mechanically and also connect them electrically.

As a result of its vast properties, the PCB industry finds it useful in electronic devices requiring high technology.

It serves various applications like the automotive industry, radar systems, space systems, satellite systems, and more.
