Printed circuit boards or colloquially known as PCBs is one of the most crucial elements used in the electronics industry. It is safe to say that it is the lifeline of the electronics industry. It is used to electrically connect the electronic parts of the machine or device. The procedure of filling the printed circuit board with electronic parts such as capacitors, transistors, resistors, batteries, etc is called printed circuit board assembly or PCBA.
At the present time, all commercially produced electronic machines and devices have printed circuit boards present in them, be it TV sets, fridges, dishwashers, washing machines, and more. Further, even a space mission isn’t viable without printed circuit boards.
It is said that the development of PCBA started in the early 1900s. At the beginning of the 20th century, a scientist from Germany by the name of Albert Hanson began the development of the PCB assembly. Later a year ago, Thomas Alva Edison carried experiments that help in the present-day PCB assembly.
After the manufacturing of the circuit board, the electronic parts which are mentioned above are attached so that a working PCB assembly is created. At the present time, there are 2 PCBA methods at the disposal which are through-hole technology and surface mount technology. In the former method, leads are embedded in the holes and in the latter one, electronic parts are situated on pads located on the PCB’s external surface. In both methods, the element leads are fixed electrically and mechanically via molten metal solder.
When it comes to soldering which is used to attach the PCB elements so as to make PCB assembly viable, there are several methods available in the market. More often than not, the selection of the soldering method counts on the volume of the production. If it is high then machine placement and bulk wave kind of soldering is used. And if the volume is low, then manual soldering is used which is carried out by hands using a microscope. Nevertheless, there are parts that are not viable to solder manually for instance ball grid array.
In the process of PCB assembly, conformal coating is done on the board after the soldering of the electronic elements. This conformal coating prevents deterioration of the board. It also prevents leakage of current. PCB boards are after assembly put in an antistatic bag so that no static charge transmits in the board especially while transporting.
No doubt, getting PCBA services from a specialized firm is better than getting it done in-house. There are a number of advantages you can expect to obtain if you hire a professional printed circuit board assembly firm. Let’s take a look at them.
Save money
If you want to set up your own assembly facility, then you have to get ready to spend a fortune. On the other hand, you can save millions of dollars by hiring a specialized firm. Further, by doing this, you can skip the hassles of hiring the right employees, managing inventory, and a lot of things.
Quality services
Taking the services of a professional PCBA firm assures that you can get quality services at cost-effective prices. A reputed assembly company has state of an art facility, dedicated and qualified staff, and years of experience to get your work on time without compromising on quality.
Focus on core competencies
If you have an expert assembly firm at your disposal, you have peace of mind and you can now focus better on your core competencies. You can have time to strengthen your brand and develop your business and do a lot more important things.
