What is Heavy Copper PCB?
Heavy copper PCB is a circuit board with a copper thickness that is ≥ 3oz per sq. ft in its outer and inner layers. What makes a circuit board classified as a heavy copper PCB is its thicker plating. During the production of heavy copper PCB, copper thickness is enhanced through plated holes and sidewalls. For instance, when a PCB has 2 ounces of copper per sq. ft thickness, it is a standard PCB. However, if it has more than 3oz of copper, it is a heavy copper PCB. Heavy copper PCB is considered a reliable wiring option. Heavy copper PCB is different from extreme copper PCB which features within 20 oz to 200 oz per sq. ft.
What does Heavy Copper PCB offer?
Heavy copper PCB has a lot to offer. It has got some unique features that make it an ideal option for high-end applications. Let’s discuss some of the benefits of this PCB; Great thermal distribution: Due to its copper-plated vias, this PCB offers high thermal resistance. Heavy copper PCB are used in applications that demand high speed and high frequency. You can also use this PCB at harsh temperatures. Mechanical strength: Heavy copper PCB feature great mechanical strength. When this PCB is used, it makes the electrical system durable and robust. Good conductor: Heavy copper circuit boards are a good conductor. They are utilized in the production of electronics due to this feature. They help to link various boards together. These boards can transfer current.
How is Heavy Copper PCB Fabricated?
For the fabrication of heavy copper PCB, plating or etching is often used. The main aim is to add copper thickness to sidewalls and plated holes. The methods used in fabricating heavy copper PCB aren’t far-fetched. Heavy copper PCBs need special etching and plating methods to ensure the extra thickness of copper. Using the normal etching techniques for the fabrication of heavy copper PCBs isn’t ideal. Normal etching methods produce over-etched margins and edge lines that are uneven. PCB producers now use advanced etching and plating methods to achieve straight edges.
Heavy copper PCBs are produced via etching and plating methods. The major aim in the production of this PCB is to add copper thickness through sidewalls and plated-through holes. Heavy copper PCBs have several benefits which make them in high demand. Due to their outstanding features and benefits, they can meet your electrical requirements. These circuit boards will always dissipate heat generated due to heavy currents conduction. Electronics using heavy copper boards have been in use for a long time. Heavy copper can carry high currents. These boards will continue to meet the needs of various applications. High power circuit wirings can be developed using Heavy Copper PCBs. Such a wiring mechanism offers more reliable thermal stress handling and offers fine finishing while incorporating multiple channels on a single layer of a compact board.
