printed circuit board assembly

This article increases your knowledge about printed circuit board assembly. Let’s start.

It is safe to bet to mention that printed circuit boards or PCBs does an indispensable role in the electronics world in the present time. No electronic product design can come to life without the usage of printed circuit boards, be it the laptop you are using now or the smartphone in your pocket, or the dishwasher in your kitchen. The circuit board solders the essential electronic components in order to route the electrical signals within the product. Owing to it, the product becomes functional.

The copper pathways are etched on the board via which the electrical current flows in the circuit board. There are several types of PCBs available in the market nowadays. You can single-sided, double-sided, multi-sided, metal core PCB, and more.

Read on to know more about printed circuit boards and printed circuit board (PCB) assembly.

Coming to printed circuit board assembly, it is basically a process of attaching or soldering electronic components like capacitors, resistors, etc. onto the circuit board.

The printed circuit board assembly process involves more than just the raw electronic elements and a finely designed board. Effective and efficient PCB assembly also calls for the correct technology. There are different assembly methods to choose from. The most popular assembly procedures are surface mount technology (SMT) and thru-hole.

It should be noted that some printed circuit board assembly processes would need just one assembly method, while some processes might call for a blend of 2 or more assembly methods. For instance, a lot of boards require only surface mount technology, while some boards require a mix of surface mount technology and thru-hole technology. You need to understand and know when and where these technologies should be used. If you do not have any idea, a reputed and experienced assembly provider can guide you while taking your project.

Each PCB assembly method has its own steps. Nevertheless, the most common steps are:

  • Solder paste
  • Element placement
  • Infrared reflow
  • Inspection
  • Testing

Picking the suitable printed circuit board assembly

Talking about the present, surface mount technology (SMT) is the most preferred choice for electronic product manufacturers. It is faster and more cost-effective as compared to thru-hole or other old-school assembly processes. However, it should be noted that it is not always the best choice. For example, if you need a more detailed and complex printed circuit board prototype that can withstand higher electric current and temperature, then thru-hole technology would be a better idea. So, you need to understand that the choice of assembly method depends upon the project and product.

Choosing a professional PCB assembly company

If you seek on the internet, you would come across a number of assembly providers. However, you need to zero down your search on the provider that can fulfill your assembly needs without straining your wallet. The most basic pointers that you should seek while choosing a professional PCB assembly company are experience and certifications.

No doubt, the experience of the company matters the most since it provides you a clear idea about the capabilities of the company. If the company has worked with a wide array of businesses, they would have experience in fulfilling strict deadlines.

Further, the certifications like ISO make sure that the company has top-notch facilities and equipment in line. By hiring a certified company, you can be certain that you will get high-quality products in view of the fact they have all that it takes to offer you the best.
