What is a Printed Circuit Board (PCB)?

PCBs are boards made of non-conductive materials with conductive lines etched from copper sheets to electrically connect electronic components such as resistors, capacitors, and ICs. They can be single-sided, double-sided, or multilayered, and may be rigid, flexible, or a combination of both. PCBs are foundational in assembling electronic devices, enabling complex circuitry in a compact, reliable form.

Types of PCB Assembly Processes

There are two primary methods for assembling PCBs: thru-hole mounting and surface mounting.

1. Thru-Hole Mounting: In this method, component leads are inserted into holes drilled in the PCB and soldered onto pads on the opposite side. This technique provides strong mechanical bonds and is often used for components that require high reliability and durability.
2. Surface Mounting: Developed in the 1960s and popularized in the 1980s, surface mounting involves soldering components directly onto the surface of the PCB. This method allows for smaller component sizes and denser layouts, reducing manufacturing costs and enabling the miniaturization of electronic devices.
