In today’s electronic age, the emphasis is more on compactness. Manufacturers of electronic items want to present products that pack in a lot of functions but at the same time do not appear bulky or difficult to carry around. Gone are the days of electronic items being too large to handle. Whether it is smart phones, computers or laptops and many other such items, they are all now available in small sizes. The best aspect is that there is no compromise on the functions and features they provide and the costs too have come down drastically. One of the main reasons for this is the evolution of the PCB or printed circuit board over the years.

Indeed, the main PCB is the basic base that holds wires of various components related to the functionality of a particular device. Most of the PCBs are generally made out of fiberglass and glass-reinforced resins that have traces of copper also within them. The various electronic devices also contain PCBs that are single or multi-layered. Computer graphic cards, motherboards are examples of multi-layered PCBs ...
... with up to a dozen layers. PCBs also come in various colors though green is the most common of them.

What are the specific advantages you can get out of main PCBs?
As mentioned above, the importance of keeping the device compact and at the same time confer the best of functionalities drives the modern electronic industry. When they use PCBs, the components within the PCB are connected through minute wires or traces inside the circuit board. They look neat and are also easier to work on in the future, as long as the PCB diagram is well drawn. The assembly is often computer aided and hence more can be fitted into the circuit board, making it compact.

This is in sharp contrast to the earlier devices when wires were longer, connected haphazardly and difficult to trace. It led to the devices becoming bulkier and difficult to manage.

The different parts of a main PCB
The PCB from the outside looks like a maze holding a number of connections, each leading from one point to the other and even interconnecting with each other. The thin lines are the replacements to the larger wires that were in use in earlier times. Then there are holes you can see in which different components can be placed depending on the need.

In the case of the microchip with 8 connections, there would be 8 holes on which the mounting of the components would be possible. This would result in a lot of saving of space and that is how today you have devices that are small to look at but can have many features and functionalities.

The components that make the features and functionalities happen are the ones that are linked within the PCB. They include diodes, switches, transistors, microchips to name a few.

Maintenance of the PCB
You have to be very careful in the handling of the PCB as it is delicate. Always wear rubber soles to prevent any conduction of static electricity, as it can cause harm to the PCB. You also need to first discharge any electricity within the body by touching metal for some seconds before you handle the PCB.

Companies like Atlanta PCB make products that have from 1 to even 90 layers. The company makes various types of PCBs as well as such as the heavy copper board, high frequency board, HDI, flex board and the like. The company besides being a leader in the local market also exports to various international markets and that is testimony to the quality of the products it makes.

The uses of the PCB are manifold within industries like electronics, medical and pharmaceuticals, automotive, telecommunication, aviation and so on.

Cavity PCB
This is so called due to the cavities made within the PCB in order to make the components height smaller so that more clearances are possible. These cavity PCBs can be assembled, reflowed and paste printed using the current capability of the equipment you have. The PCBs are mainly in use for making antennas, microwave, automotive and telecommunication industries.

Rogers PCB
When you require electronic devices that make use of materials that are more in number, then the Rogers material is very useful. Typically, high frequency circuits make use of this type of PCB to boost electrical conductivity. In the aerospace, defense and mobile network applications, this Rogers PCB is the most favored one.

Rogers PCB
This PCB is made of a material called the FR4 or Flame Retardant Level 4 one, which contains the epoxy composite of glass fiber and with copper foil lamination on either one or on both the sides. These have high frequency attributes like the Teflon and though more costly than the fiber glass one, are used due to the low losses of conductivity at higher frequencies. They thus make for good RF circuit boards.

The advantages of low electric signal loss, much less dielectric spillage and better impedance control makes the Rogers PCB very useful indeed.

BT PCB
Today there is an increase in the usage of substrate mounted components, especially where there is semiconductor technology being used. The PCB has to therefore have high heat resistance so that there is better electrical conductivity. It also must have lower dielectric loss and that is why the BT PCB with its resin-based composition, is so preferred.

BT or Bismaleimide- triazine has a copper laminate, which makes it ideal for high-density interconnect usage. The resin has high degrees of mechanical, electrical and thermal properties, which makes it very useful in applications like plastic packaging, LED chips, high frequency devices where such properties are most necessary for the effective functioning of the devices.

As you would have seen above, the main PCB is one of the most important discoveries in recent times. The different types of PCBs as described above are all very crucial to the smooth working of devices across various industries.
