The Printed Circuit Board is an essential component found in several electrical gadgets. It is also present in hefty types of machinery used in numerous industries. Designing a faultless circuit board for devices requires understanding the roles copper plays.
Modern PCBs have power devices that operate on high current intensity and a strong ion flow. Their electrical conductivities are from copper. Copper is an electricity and heat conductor. It produces little heat that cannot cause damage to the board. Its thermal conductivity strength regulates the heat pressure.
Thermal conductivity enhances the transfer of pressure caused by excessive heat. Other components in the electrical gadgets share the extreme heat within themselves. It also boosts the PCBs capability by transferring signals without loss of electricity.
Furthermore, it is vital to note that copper has various weights/thicknesses. The choice of copper density hinges on the end product in mind. Another factor to consider is the amount of current that would pass through the PCB. The standard copper density for the internal layers of the board ranges between 1.4mm to 2.8mm. The external layers have a copper density of 2oz to 3oz.
A thick copper PCB is a board with a copper weight greater than 3oz per sq/ft both in its internal and external layers. The thick plating in the 8oz PCB design affirms it as one of the heavy copper PCBs. The thickness increases via plated holes and sidewall during production.
However, this article will concentrate on a higher copper density of 8oz PCB. The 8oz PCB is present in power electronic gadgets and power supply systems. This thickness is perfect for devices that are at risk of damage.
