It is a well-known fact that the main PCB or for that matter, Rogers PCB, Cavity PCB and BT PCB are all the at the heart of any electronic device. If you have noticed that the sizes of electronic devices have come down drastically over the years, you have to thank the PCB or Printed Circuit Board.
This PCB is the base on which the circuitry is done for the device. However complex or intricate the circuitry, it can be done on the PCB. No longer do you have to contend with wires of all kinds hanging ungainly and making the device bulky. The PCB enables any device to perform multiple features and functions without adding to the bulk. Not only that, thanks to the design and optimized use of the PCB, the cost too can come down drastically.
Different types of PCBs
The main PCB is the printed circuit board and we have already talked about it. The Cavity PCB is the one that has holes in it to make the components appear smaller. This will aid in making the thinnest of devices possible. Nobody wants to take a bulky or heavy device with them, especially with so many people working out of home. The Cavity PCB is the reason why you have the thinnest of laptops, this PCB is also used in the making of the LED monitors and for televisions.
The BT PCB on the other hand comes into play due to the need for semiconductor technology being so prevalent in today’s times. There is a requirement for using substrate mounting and the BT PCB makes use of the epoxy resin with copper lamination to ensure that the device does not heat up. This resin Bismaleimide triazine enables excellent electrical connectivity, higher heat resistance and lower dielectric loss. These attributes make the device perform very well.
The Rogers PCB is the one using the FR4 technology or Flame Retardant Level 4. This is typically used in devices that require complex circuitry, where there is need to pack in a lot of diodes, resistors and the like. The usage of this Rogers PCB in fields of aviation, telecommunication and defense is very common. This PCB enables very less spillage of conductivity even at higher frequencies. They come with single or double packed copper foils.
