What is copper based PCB?
Copper based PCB is the most expensive in metal core PCB, which has a great thermal conductivity better than aluminum PCB and iron based PCB. Suitable for high frequency circuit and high and low temperature variation area as well as precision communication equipment heat dissipation and building decoration industry.
A Metal Core Printed Circuit Board (MCPCB), also known as a thermal PCB or metal backed PCB, is a type of PCB that has a metal material as its base for the heat spreader portion of the board. The thick metal (almost always aluminum or copper) is covering 1 side of the PCB. Metal core can be in reference to the metal, being either in the middle somewhere or on the back of the board. The purpose of the core of an MCPCB is to redirect heat away from critical board components and to less crucial areas such as the metal heatsink backing or metallic core. Base metals in the MCPCB are used as an alternative to FR4 or CEM3 boards.
The metal core of the thermal PCB can be aluminum (aluminum core PCB), copper (copper core PCB or a heavy copper PCB) or a mixture of special alloys. The most common is an aluminum core PCB. Other materials, like brass or steel, are sometimes requested but are not recommended. The metal PCB materials are very hard and cutting the PCB into smaller pieces can pose problems. Other considerations in selecting metal PCB materials are the chemicals in manufacturing and if the metal will react to them.
The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are possible.
MCPCB copper foil thickness can be 1 - 10 oz. Accumulation of too much heat in printed circuit boards lead to malfunctions in the devices. Electronic devices that generate a considerable amount of heat cannot always be cooled using conventional fans. Conductive cooling through metal core boards is an ideal option. In conductive cooling, the heat is transferred from one hot part to a cooler part by direct contact. This works well since heat constantly seeks to move to any object or medium that is cooler. YMSPCB is a leading manufacturer of PCBs and PCBAs in China. Our large facility can handle small-large volume orders without the restriction of the minimum pieces; you can also order one PCB. We offer quick PCB prototypes and turnkey PCB assembly services. Everything can be done under one roof, and we take responsibility for every process.
