Modern electronic products, such as computers, telephones, televisions, and even smaller electronic devices like smart watches and fitness trackers, rely heavily on PCBs. Printed wiring boards (PWBs) are crucial components that consist of a base board that supports all of the other parts and circuitry, as well as a patterned layer of electrical tracks printed on top of it.
A printed circuit board (PCB) is made up of four major components:
• Substrate: The first and most important step is the substrate, which is generally made of fibreglass. Fiberglass is used because it strengthens the PCB's core and helps it resist breakage. Consider the substrate to be the PCB's "skeleton."
• Copper Layer: Regardless of which approach is used, the copper's role remains the same: to convey electrical messages from the PCB to the brain and muscles, exactly like your nervous system does.
• Solder Mask: The third component of the PCB is the solder mask, which is a polymer layer that protects the copper from short-circuiting when it comes into contact with the environment. In this case, the solder mask acts as the PCB's "skin."
• Silkscreen: The circuit board's final component is the silkscreen. On the component side of the board, part numbers, logos, symbols, switch settings, component reference, and test points are frequently silkscreened. The silkscreen is also known as a legend or nomenclature.
Printed Circuit Boards are widely used in television sets, transistor sets, radios, amplifiers, ampligrams, stereo amplifiers, voltage stabilisers, calculators, telecommunication equipment, power supplies, public address equipment, computers, and defence and other research organisations.
When component connection leads are present on current PCBs, they are usually in the shape of a little foot. So they can be soldered to the copper tracks directly and put on the same side. This not only saves money by avoiding expensive drilling and through-board track hookups, but it also allows for the use of surface mounting devices (SMDS), which are frequently smaller and potentially less expensive than their traditional counterparts and allow for significantly higher component packing density.
The most frequent components found in SMD form are capacitors and resistors. These are small rectangular blocks with metal caps on the ends that link each internal electrode all the way around. The components are not connected by wires.
PCBs are found in almost every electronic product, ranging from consumer electronics such as PCs, tablets, smartphones, and gaming consoles to industrial and even high-tech goods in the strategic and medical electronics fields. Given the importance of the PCB industry in the electronics manufacturing ecosystem, an article titled 'How will the Indian PCB industry grow?' published in the April 2016 issue of Electronics Bazaar, which featured the opinions of major industry stakeholders.
In comparison to the rest of the world, the Indian market is distinct. Flexible circuits are expected to grow far quicker in the global market than rigid PCBs, because the former can lower form factor and eliminate connectors. However, most Indian PCB manufacturers focus on single-sided, double-sided, and multi-layered PCBs with four to six layers.
The Indian electronics sector is one of the fastest growing in the world, with domestic manufacturing topping US$ 100 billion and predicted to reach US$ 400 billion in 2022. As a result, the PCB market will benefit tremendously.
PCB demand in the home market is expected to grow at a CAGR of 20.56 percent from 2015 to 2020, reaching over US$ 6 billion by 2020, up from US$ 2.38 billion presently, according to an ELCINA report.
