What are the important things to know about PCB assembly

The printed circuit board assembly or PCB assembly process is a complex sequence of steps that transforms a PCB design into a functional electronic product. It requires coordination between the PCB fabrication house, component suppliers, and the assembly factory to source all required materials.

The assembly process itself consists of soldering surface-mount components and through-hole components to the fabricated PCBs using solder paste printing, pick-and-place machines, wave soldering systems, and manual soldering. Each step introduces opportunities for defects if not executed properly.

That's why comprehensive testing and inspection are critical at multiple stages: after SMT assembly, after through-hole assembly, and as a final quality control check. Electrical tests validate connectivity and basic functionality, while automated optical inspection examines every joint for potential soldering defects.

When done correctly, this complete printed circuit board assembly process results in a high-quality and reliable circuit board assembly, ready for installation in an electronic product. Careful attention to quality controls and process validation is essential, as small flaws in assembly can lead to field failures down the line. The investment in diligent assembly practices pays dividends through increased product quality and reliability.

Popular methods for PCB assembly

SMT - Surface mount technology (SMT) is a method of attaching electronic components to printed circuit boards using a paste or glue. Surface mount technology has been widely used in the electronics industry since the 1970s, but it has recently become popular with hobbyists and DIYers who want to build their electronics projects without having to solder them.

The main advantage of surface mount technology is that it allows for a more compact and efficient design than traditional methods because there are fewer connections between components, which means less wasted space on the PCB or wasted time when trying to connect wires correctly.

THT - Through hole technology or THT is a method of component placement used in the manufacture of printed circuit boards (PCB).

In through hole technology, components are mounted on a printed circuit board by passing their leads through pre-drilled holes in the board and soldering them to the copper traces on the other side. The technique provides for easy assembly and repair of electronic devices but is less suitable for miniaturization than surface mount technology (SMT).
