Rogers PCB – How to make the most of it

It is normal for anybody to think of the Main PCB existing only within computers, laptops and the like. However, the PCB is something that is found in other electronic devices as well. Rogers PCB is a more commonly used PCB.Televisions, monitors, digital cameras, mobile phones are other examples where this wonderful piece of board plays a major role in the smooth functioning of the device.

Uses of Rogers PCB

In addition to the above-mentioned devices, the PCB in the form of Cavity PCB, BT PCB or Rogers PCB are also found across medical devices, they are used in lighting, for industrial machinery, defense, automotive and aerospace industries. It is thus clear that the PCB is probably the most important component within the electronic devices used in the above industries.

The discovery of this component has led to a major change in the manner electronic devices are being manufactured. Earlier, the devices used to be bulky and with more features being added, the device became heavier. There were far too many wires involved and the portability was an issue.

The PCB has changed all that. You can now have this PCB board supporting all the wiring of the device as connecting traces. The result is devices have become smaller, they can have more functions and the cost too has come down. Moreover, portability is no longer a problem. Some of the most complex laptops, have PCBs that run the device and when you open the laptop, you will see the PCB having a maze of wiring connections, apart from the many diodes, resistors and the like powering the device.

Within the medical field for instance, the Rogers PCB and BT PCB have made the medical evaluation, testing equipment manufacturing pretty convenient. Today you have the best of pacemakers, scan machines, x ray equipment having the densest of PCB architecture. This has not only brought down the size of such equipment but also made them pretty affordable and easy to use. Click here to know more;

Single and Multilayered Main PCBs——Rogers PCB

For devices that are simple, a single layered PCB would suffice. With increasing complexity, multilayered PCBs become necessary. High powered computer graphic cards and motherboards are examples where the PCB may have up to 12 layers.

The single layer PCB has a substrate of a single layer and its one side is coated with copper. This metal is used due to its excellent electrical conducting property. The protective solder mask is put on the copper base plating. The single layer is easy to make as all the components are typically soldered on one side.

The double layered PCBs have the base layer on both the board sides and holes are then drilled through in order to enable the circuits to connect with the circuit on the other side. The wires are passed through these holes for the connections to take place.

The other way to enable connections of the circuit is through the surface mounting of the board. Here, the wires are not the connectors but many small sized leads are directly soldered into the board and hence the board becomes the wiring surface. In such a board, the circuits can be completed without using up more space and there is space left on the board to allow more functions that can enable the device to deliver higher speeds, become lighter.

The double-sided PCBs are used in power supply, LED lighting, automotive dashboards, vending machines to name a few.

Coming to multi-layered PCBs, they are made up of more than 3 double layered PCBs. The PCB boards are then held together using a special glue that is sandwiched between insulation pieces so that the heat generated during the functioning of the device does not end up melting the components. The sizes of multi layered PCBs may vary from 3 – 12 layers with the largest ever made being of 50 layers.

More the layers, more the complexity of the device. The uses of such boards are in file servers, for GPS technology, weather analysis, satellite systems, complex medical equipment to name a few.

In addition to multi-layer PCB, there are Rogers PCB, etc

Apart from the single and multi-layered PCBs, there are rigid PCBs, high frequency PCBs or Rogers PCBs, rigid-flex PCBs and BT PCBs.

Within the industrial machinery space, the PCBs play a huge role. Thick copper PCBs are now fulfilling the role that a one-ounce board is no longer able to, due to the complexity involved. These are used extensively in high-current chargers, load testes and motor controllers.

When it comes to lighting, the emphasis is on lower power consumption along with efficiency. So, the aluminum-based PCBs are being preferred due to them being able to allow higher heat transfer as compared to the standard PCB. The high lumen-based LED applications also make use of these type of PCBs.

The flexible PCBs are the ones that are used within the automotive as well as aerospace industries. These have to work in environments that are high vibration and at the same time, be light weight. Due to the need for compactness for applications like instrument panels or dashboard, the flex PCB is the best suited.

The rigid PCBs have boards that do not bend or twist. The substrate material used allows for communication between the many parts of the device. One example is the computer motherboard which has to interface the GPU, RAM and CPU. These PCBs are among the largest numbers to be made as they have to maintain the shape through the working of the device in its lifetime. They can be single or multi layered.

The Rogers PCB caters to devices that require higher frequencies and better electrical conductivity. The defense, telecommunications and aerospace industries favor such PCBs the most. They are made out of FR4 material.

The BT PCBs are the ones where semiconductor technology is being used. The PCB will have to be highly heat resistant. The BT or Bismaleimide – Triazine resin is used with the copper laminate, which confers high thermal, mechanical and electrical properties to it.
