PCB: Introduction, Types, Uses, and Many More

Printed Circuit Board or PCB boards are a collection of several microcircuits in one sheet or board. The idea behind PCB development is to make electronic devices more compact and functional. Currently, analysts agree that PCB boards’ development helped the technological leap in the past years without a doubt. The PCBs evolved with time, and now they have several types depending on their various usage. So, scroll below to get some ideas about how PCB affects the electronic industry for the better.

Types Of PCB

Depending on the layers

PCB boards are of three primary types depending on the compatibility and work strategy. There are single-layered, bilayered, and multi-layered PCBs available in the market. In this variety, only one side is coated with metal. Copper is widely used for the purpose. Then the makers dip it in the etch of ferric oxide to shape and tone. Finally, adding a silkscreen finishes the structure. Single layered PCBs are very famous and highly functional. By the term high applicable, we don’t mean it’s highly efficient and thermo compatible. But, these chips are significantly cost-effective, and you can use them in various electronic materials. Then comes the double-layered or the bilayered PCB. The primary build-up is the same. Just here, we use both sides of the board. The holes are pinned and heat-sealed to connect both sides. Or the surface mounting technology is also helpful. In surface mounting, the holes or vias don’t act as connectors. Here we solder the leads directly to the board. As a result, the whole board serves as the wiring system. It means you will need fewer resources and space to accumulate the same amount of chips. The multi-layered PCB has three or more layers of bilayer PCB boards. These expansions are mainly the indicator of their high capacity and efficiency. The bi-layer boards are glued together, and there is insulation between the two layers. Multi-layered PCB boards are used mainly in data storage, file server, satellite automation, and such sectors.

Depending on the rigidity

Rigid PCB

Rigid PCBs are made up of twist-resisting materials and remain the same before exceeding the tolerance limit. The most known examples are the motherboard, GPU, CPU, and such. They are single, bi, or multi-layered. According to the data, rigid PCB is the most produced PCB board among all the subtypes.

Flexible PCB

Flexible PCBs are developed from fiberglass or such core, allowing a bend worthy, waterproof, shockproof, erosion preventing, and tension resistant structure. Though the fabrication cost is a bit more in this variety, the outcome is worth the investment. There is another type called the flex-rigid PCB. The traditional lower rigid board is covered with a flexible panel that streamlines data flow and effectivity.

Functions Of PCB

The area of application of PCB is vast and getting even spread every day. The medical sector is surprisingly one of the most benefited sectors by the PCB. X-Ray machines, CAT scans, MRI machines are better than ever, and the doctors can diagnose a disease accurately in the shortest period. In the heavy machinery industry, where the usual one-ounce copper sheets are not compatible today, multi-layered PCB boards work wonders as load testers. The recent craze LEDs known for their less power consumption, are high lumen, aluminum backed up PCB boards. Smartphones, laptops, and electronic gadgets are evolving faster than ever.


PCB tech is the mainstream of our tech trivia in this millennium. The designs and affordability are getting better each passing day, intending to connect the world. Read more:  myworldnews24.com
