AN INTRODUCTION TO PCB MANUFACTURING; A MEGA INVENTION IN THE WORLD OF ELECTRONICS

PCB stands for “Printed Circuit Boards”. It is responsible for creating the backbone of all major types of electronics. This is a kind of miraculous invention by pcb manufacturer that are a major part of even minor computational electronics such as calculators or digital clocks.

The pcb manufacturing is responsible for routing electrical signals via electronics. It is done to provide all the mechanical and electrical requirements needed by the circuit. Pcb manufacturing is an electrical instructor that tells the electricity its direction and makes your electronic alive.

Pcb manufacturer brought a revolution in the world of electronics by kicking out wired point-to-point method of circuit completion. Pcb manufacturing started in the early 20th century from its basics. This technique is modernizing day by day bringing more ease and technology to the world of electronics.

The main part of pcb manufacturing, the “PCB”, is made up flat sheet of insulating material along with a copper foil layer that is laminated to the substrate. Track or circuit traces are the conducting lines through which the chemical etching divides the copper. The copper is also divided into pads for connections and vias to pass connections among copper layers.

The pcb manufacturer added protective coating to the surface of printed circuit board to protect copper against the corrosion. A printed circuit board typically made in pcb manufacturing may have several copper layers. A bi-layered board may have copper on both of its sides whereas a multilayered board by an expert pcb manufacturer may have multiple copper layers sandwiched in between insulating material layers.

Some of the very common insulating substrates used in the pcb manufacturing of multilayered boards are FR-4 glass epoxy and cotton paper impregnated with phenolic resin (commonly brown or tan). When the pcb manufacturer do not integrate any component in the board, it is known as etched wiring board or a printed wiring board (PWB).

Printed circuit boards or simple and basic product of pcb manufacturing is commonly referred to as “printed circuit assembly” with the components. When a printed circuit board is heavily populated with electronic components it is entitled as “a printed circuit assembly” (PCA).

A pcb manufacture may craft a printed circuit board being printed with “silkscreen” along with a legend that is responsible for components identification, testing points, or to identify text as well.

When the result of pcb manufacturing is a minimal printed circuit board for only a single component, it is called as a breakout board. The principle purpose of this breakout board as per pcb manufacturer is to “break out” the component’s leads on separate terminals in order to create an easy manual connection among them.

The world market consisting of pcb manufacturers was stated to exceed $60.2 billion in the year 2014. By the year 2024, it is estimated by the Global Single Sided Printed Circuit Board Market and mentioned in its analysis report that the pcb manufacturing market would reach $79 billion.
