Metal core PCB, MCPCB, is a general term of PCB in which traces are made on top of one layer of metal plate for improved heat transferring and dissipating purposes. The most common metals for heat dissipation are aluminum and copper. Aluminum has good heat transfer and dissipation abilities, but yet relatively cheaper. On the other hand, copper has even better performance but is relatively more expensive. Therefore, the majority of MCPCB is made out of aluminum.
Applications of MCPCB can be categorized into two different types, the industrial and consumer product segments. MCPCB is not a new technique or a new product. It has been on the market for decades. It was broadly used in high power & high voltage heavy electrical equipment, medical equipment, and military products, even in power supply, rectifiers, and transformers. It is a matured technology and product.
Recently, the continuing trend of electronic device miniaturization and introduction of high power LED, MCPCB, with better heat-dissipating capability than traditional PCB, is making it even more popular in consumer segments. These new applications are LED backlight, LED lighting, and automotive. The key to the success of these applications is determined by the selecting correct high thermal conductivity insulating layer, known as dielectric or PP.
The material used for MCPCB is called Insulated Metal Substrate, IMS. Its structure consists of three different materials, on top is the copper foil; in the middle is the PP (or so-called dielectric); at the bottom is the metal plate. The most common metal plate used is aluminum or copper.
Nowadays, the hottest consumer application in MCPCB is LED. That’s because the dissipation of heat is getting more attention from the designer. The reason is that both lifespan and luminous decay of LED are all directly linked to the junction temperature of the LED. Moreover, the led junction temperature is also related to energy consumption. According to an experiment conducted by Cree, the time for luminous decay drop to 70% is 100 thousand hours if the temperature is kept at 65 Celsius. Many tests have proved that LED generates heat is because electricity input cannot completely transform to light but heat. The luminous efficiency of LED is about 100lm/W. The electricity-luminous conversion ratio is only between 20~30%. That means about 70% of current input turns into heat. By reducing heat generated, we can increase luminous efficiency and conserve energy.
