You must have used a smartphone or laptop at some point, but ever thought about how they really work? Well, one of the most important aspects is the printed circuit board. It is basically a process of mounting electronic components on a board. There are primarily two methods through which this is achieved: Surface Mount Technology and Through-Hole Technology.

Quality control is paramount, and testing—for example, X-ray and optical inspections—is done to detect errors. Understanding the details of the PCB assembly allows appreciation of an otherwise complex world. This post breaks down everything about the assembly.

SMT Process—

SMT is the most common method for modern electronics. It's fast, efficient, and has the benefit of tiny components. First, a sticky paste called solder paste is applied to the board. Then the tiny components are placed on the paste using high-speed machines.

The THT Process—

THT is older but still used for some components. It's slower than SMT but often easier for larger parts. Components with leads are inserted through holes in the board. Solder is then applied, usually by hand or a wave soldering machine.

Quality Control—

Making sure PCBs work correctly is very important. Once assembled, boards undergo a number of tests. Optical inspection checks for parts not installed or installed incorrectly. X-ray inspection looks at the interior of the board for problems that may be hidden from view.

PCB Design and Components—

First, a design of the PCB is made for assembly. This has the inclusion of where all parts will go. The design shows information on the size and shape of the board, where copper tracks for electricity are, and where the holes for components are.

The components used within a PCB vary greatly. Common ones include resistors, capacitors, transistors, and ICs—that is, integrated circuits. The components to be used are determined by the function of the electronic device.
