Metal Core printed circuit boards, are those which have a built in base metal core. This core helps in dispersing heat, which emits from different components of the board. Dispersion of heat, helps the application, reduce its core temperature. In this manner, the application is able to keep itself safe from getting damaged.
Not all applications use this pcb. The application of high frequency PCB is limited to only those who cannot be cooled by using conventional fan-cooling technique. Some of the most popular materials used in these boards are as follows:_
Aluminum Core PCB
Heavy Copper PCB
A mixture consisting of various special alloys
Significance of High Density Printed circuit boards
The prime significance of metal core circuit boards is that they are able to transfer the heat of the component, at a much faster rate. It is estimated that they are 8 to 9 times faster than their nearest contemporary. As these boards laminate, scatter and eliminate heat, with-in a very short time, they are able to keep the different sections of the device much cooler. It is this aspect which helps these devices improve and increase their performance. Draining of heat also helps these applications or devices survive for a much longer period. It is due to some of these features, heavy copper pcb boards have become quite popular with the LED based appliance manufacturers. In current times, these boards are being used in almost all the LED devices.
Some LED applications where PCB Assembly is commonly used:-
Streetlights and in other lighting equipments.
General lighting based applications.
System automotive application of the LED. In Power Converters such as Telecom, High Voltage Regulator, and other Power Supplies. In Hybrid Motor Control Applications. In Photovoltaic Devices. Why High Density PCB are used in LED equipments The prime drawback of the LED devices is that they emit a huge amount of heat. In case, if this heat is not diverted or eliminated, then it can seriously damage the device’s performance. To save the performance of the LED device from getting effected, it is necessary to use high density metal core boards.
