Everything You Must Know About PCBA or Printed Circuit Board Assembly

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.

Printed Circuit Board Assembly: Why outsourcing it is a better idea!



It usually doesn’t seem rational to invest in costly fabrication equipment in case you just wish to spin some prototypes and rather outsource you're (PCBA) printed circuit board assembly & prototype fabrication to a dependable vendor.

A few contract fabricators would provide a quick quote system over their site for the fabrication of circuit boards & assembly of prototypes. This would bank your time whilst comparing different vendors. Ensure that the quote mechanism facilitates you to fill in all of the details, for instance, board material, thickness, copper thickness, milling, and much more in order that you could get a precise quote without any surprises afterwards.


Often the price per board would lessen down as quantity augments. This is owing to the pretty high setup price of circuit board fabrication & element assembly. A few vendors would employ a mechanism where they join boards from various clients. This manner the setup price would be distributed among various clients. When you fabricate an item, you certainly don’t wish to have to fabricate a big quantity of boards straight away whilst you enhance your design.

One constraint with little quantity prototypes though is that the selection of materials & material thicknesses would be restricted. In case you are employing a particular material then opportunities are there will not be any other clients employing the same material. Besides, lead time plays an extreme role in measuring price. A longer lead time facilitates the fabricator more liberty in slotting your fabrication. This is usually reflected in lower prices than you would observe in the quoted segment. Certainly in case you are in a hurry and wish to be moved to the zenith of the pile you would require spending more dollars.

Ensure that your contract fabricator would support the file set up for the fabrication that you offer. The most popular format for printed circuit board fabrication is the Gerber format nevertheless a few vendors would also embrace board files from popular PCB software items. A few suppliers also provide in house Printed Circuit Board design. Even in case you create your board yourself, choosing a vendor with design services might provide resourceful if there is an issue with your files. In this scenario, your vendor could make rapid changes that would neglect expensive delays.

To make certain that your circuit boards would function well, be certain that your vendor is quality certified & provides the tests & board inspection procedures which are needed. Please note down, nevertheless, that particular tests, for instance, ICT testing calls for extra time and price to prepare appropriate test fixtures.
