This article will briefly introduce thick copper PCB and list 10 thick copper PCB manufacturers.
About thick copper PCB
Copper thickness refers to the thickness of copper foil, which is a thin, continuous layer of metal foil deposited on the base layer of the circuit board. It is used for conductive conduction of the PCB. Copper thickness is divided into inner layer copper thickness and outer layer copper thickness, which are measured in weight unit oz. Generally, the copper thickness of single-sided and double-sided PCBs is 1oz; the outer layer of multi-layer boards is generally 1oz and the inner layer is 0.5oz.
A high-current PCB or thick copper PCB contains 3 ounces or more of copper in the outer and inner layers of the board. Thick copper plates are applicable to a wide range of fields, including mobile phones, microwaves, aerospace, satellite communications, network base stations, hybrid integrated circuits, power supply high-power circuits and other high-tech fields. Thick copper plates have excellent elongation properties, are resistant to high and low temperatures, and are resistant to corrosion. They allow electronic equipment products to have a longer service life and are also very helpful in simplifying the size of electronic equipment. In particular, electronic products that need to run higher voltages and currents require thick copper plates.
Performance of thick copper PCB
Thick copper PCBs have the characteristics of carrying large current, reducing thermal strain, and good heat dissipation. It is not limited by the processing temperature. Oxygen blowing can be used when the melting point is high, and it is not brittle at low temperatures. It is also fireproof and is a non-combustible material. Even in extremely corrosive atmospheric environments, copper sheets form a strong, non-toxic passivation protective layer.
Advantages of thick copper PCB
Thick copper PCBs have a lot to offer. It has some unique features that make it ideal for high-end applications.
Huge Thermal Distribution: This PCB offers high thermal resistance due to its copper-plated through-holes. Thick copper PCBs are used in applications requiring high speed and high frequency. You can also use this PCB in harsh temperatures.
Mechanical Strength: Thick copper PCB has high mechanical strength. When this type of PCB is used, it makes the electrical system durable and strong.
Good conductor: Thick copper circuit boards are good conductors. Due to this property, they are used in the production of electronic products. They help connect various boards together. These plates can pass electrical current.
On-board heat sink: Thick copper plate provides on-board heat sink. Using these panels you can achieve an effective heat sink on a mosaic surface.
Huge dissipation coefficient: Thick copper PCBs are ideal for large components with high power dissipation. These PCBs prevent electrical systems from overheating. They dissipate heat efficiently.
Supports special materials: Thick copper helps protect and enhance special materials. Special materials are sometimes used to design electronic components. Extreme temperatures may require an special material. Thick copper plates put an end to circuit failures because they use an special material to fully function.
