6 Reasons Why We Choose Printed Circuit Boards

In a simple electronic device like a calculator, PCBs are used to connect the various components such as the display, buttons, and microcontroller. Without a PCB, it would be difficult to establish these connections in a neat and organized manner.Why is it necessary to use PCB in electronic devices?

PCB (Printed Circuit Board), also known as a printed wiring board, is an essential component in the electronic industry. PCB is used to establish electrical connections between various electronic components, ranging from small electronic devices like watches and calculators to large systems such as computers, communication devices, and military weapons systems. PCBs are composed of an insulating substrate, connecting wires, and assembly soldering. PCB Assembly is the process of assembling and soldering electronic components onto a printed circuit board (PCB). It involves the use of automated equipment to place surface-mount components, as well as manual soldering for through-hole components.

 

 

Here are 6 main advantages of PCB：

Compact design: PCBs offer a more compact and neat design solution as compared to traditional wire-wrapped circuits. The components of a PCB are mounted on a single board, which takes up less space and reduces the overall size of the electronic device.

High reliability: PCBs are highly reliable because they are made using automated manufacturing processes that ensure consistency in the production of each board. This results in fewer defects and higher quality assemblies.

Easy to repair and maintain: PCBs are easy to repair and maintain because it is relatively easy to locate and replace faulty components on the board. You can quickly diagnose and fix problems. The board is built with labels indicating the polarity of the electronic components. It is simple to check for problems and make replacements. This makes it easier to troubleshoot and fix malfunctioning electronics.

Cost-effective: PCBs are cost-effective for high-volume production as they can be fabricated in bulk using automated processes. This reduces the overall cost of production, making them an ideal choice for mass-produced electronic devices.

Durable: PCBs are durable and can withstand harsh environments, such as extreme temperatures, humidity, and vibrations. This makes them suitable for use in a wide range of industrial applications.

Less electronic noise: Electronic components are organized on a PCB with a minimum amount of space between them. This drastically lowers the electrical noise. A PCB also helps to lessen electromagnetic radiation and pickup. As a result, there is less crosstalk between the components on the board. This is typically a significant issue when developing electronic circuits. A PCB can help reduce electronic noise if the components are arranged carefully. But if the arrangements aren't done properly, the noise might degrade the circuit board's performance.

 

Overall, PCBs offer several advantages over traditional wire-wrapped circuits, making them an ideal choice for electronic devices requiring high reliability, compact design, and cost-effectiveness.
