Heavy PCB is basically a printed board with a copper thickness above than 3 Oz and less than 15 OZ. If the thickness reaches above than 15 Oz, then the printed board is considered as extremely heavy copper printed boards. Heavy or thick are usually the name given on the basis of copper thickness in the circuit. Such boards are designed with heavy copper board technology that allows them to integrate with complex switches even within a limited space. The PCB is designed with different circuitry to provide higher level of current to the device where that is going to use.
A heavy copper PCB delivers excellent performance to the user because of its development with copper planes and traces in proven designs. This board is ideal to handle high level of current and high voltage very well because of its accurate copper thickness. When it comes to power distribution, this heavy copper board is ideal to efficiently supply power in a reliable manner. Apart from using in power distribution, these boards are also suitable to use in power convertors, heat dissipation and planar transformers. The construction of the printed board includes conductors whose thickness and width is provided based on required carrying capacity of current.
Unlike other PCB, the heavy copper PCB is capable to work in touch conditions like frequent exposure, excessive current, elevated temperatures and recurring thermal cycling. They can be useful in various equipments in defense and aerospace industry due to their excellent tolerance capacity that allows them to work in rough conditions efficiently. Apart from this, such kinds of copper boards are also applicable to use in computers, automotives and other equipments to distribute power effectively. Because of their excellent capacity and strong structure, the boards are much expensive as compare to the regular boards.
