During your stay on island is no standard explanation of Heavy Copper, that is generally accepted of which if 3 ounces (oz) of copper or even more can be used on the interior and external layers of any printed circuit board, it truly is called a heavy water piping PCB. Any circuit together with a copper thickness regarding more than 4 ounces per square foot (ft2) is also categorized since a heavy copper PCB. Extreme copper means something like 20 oz per ft2 to be able to 200 oz per ft2.
A heavy copper PCB is identified as a new PCB with a water piping thickness 3 oz each ft2 to 10 ounces per ft2 in typically the outer and inner tiers. A heavy copper PCB is produced with water piping weights ranging from some oz per ft2 to twenty oz per ft2. Typically the improved copper weight, together with a thicker plating and correct substrate in the through-holes can alter a weak panel in to a long-lasting and dependable wiring platform. Heavy copper conductors can increase the entire PCB thickness considerably. The copper thickness should always be considered during the circuit design stage. The current-carrying capacity is determined from the width and thickness of heavy copper.
The primary benefit of heavy copper circuit boards is their capability to survive frequent exposure to excessive current, elevated temperatures and recurring thermal cycling, which can destroy a regular circuit board in seconds. The heavy copper board has a high tolerance capacity, which makes it compatible with applications in rough situations such as, defense and aerospace industry products. Some of the added advantages of heavy copper circuit boards are:
1.Compact product size due to several copper weights on the same layer of circuitry
2.Heavy copper-plated vias pass the elevated current through the PCB and assist in transferring the heat to an outer heat sink
3.Onboard high-power-density planar transformers
Heavy copper PCBs are used for multiple purposes such as in planar transformers, heat dissipation, high power distribution, power converters, etc. There is an increased demand for heavy copper-clad boards in computer, automotive, military, and industrial controls. Heavy copper printed circuit boards are also used in:
1.Power supplies, power converters
5.Solar panel manufacturers, etc.
