PCB assembly or PCBA involves processes, technologies, tips, and strategies in order to produce quality outcomes. Hence, PCBA is the method of assembly or soldering electronic parts to the PCB. The circuit board before assembly of the electrical parts is called PCB. After all the necessary parts are soldered, you now call it “printed circuit assembly” or printed circuit board assembly. It’s also important to take not that assembling circuit boards varies from the manufacturing process. This is why you need PCBNet to help you understand the specialized techniques in creating ideal PCBs in the market.

PCB Fabrication PCB assembly includes various methods such as PCB prototype creation and PCB design. Here, you can get the various methods of PCB assembly. After the PCB is done, the electrical components are soldered prior to using the gadget or electronic equipment. The assembly process actually depends on the specific type of boards, electronic components, and purposes you are targeting. And in order to complete the assembling of these parts, you will need printed circuit board, electronic components, soldering materials, soldering flux, and soldering equipment. If you have all these requirements, you can now arrange the raw materials and electronic parts in order to begin the process of assembling.

PCBA with Through-Hole Electronic Parts

Electronic parts which contain leads from and to the through-holes for soldering process actually refer to the through-hole electronic parts. The soldering or assembly process involves hand soldering and wave soldering wherein solder bars is used at high temperature bath. The solder stays within the bath via molten form while forming waves at extremely high temperature. However, it’s important to understand that the temperature may depend on soldering type used. The traditional lead or tin solder contain low melting point unlike lade-free solder.

The PCBs with through-hole electronic parts are passed over via molted solder by using conveyor belt.The following are the steps included during te whole-wave soldering process:
  • Insertion of electrical parts
  • Flux application
  • Pre-heat
  • Cleaning
  • Testing

After this process, PCBs are then cleaned before they are tested. If there are faults or errors in solder joints, it is reworked through hand soldering done within manufacturing units where repair and rework jobs are completed. An excellent quality soldering iron or soldering station, flux, and solder wire are used when finishing this process.

What Are Surface Mount Technologies or SMTs

SMTs are PCBAs for SMD electric parts. The SMD parts do not actually have legs or leads so they are attached on the circuit board’s surface. However, the soldering materials, electric parts, and tools used in assembling the boards differ from through-hole soldering method. With the multiple steps needed in PCB assembly, you will need an expert assistance in order to help you produce the right ones for your business. You can count on PCBNet to guarantee results after the entire process.


When it comes to assembling and testing through-hole tech and SMT, there are various components to be considered before starting the process. For through-holes, component leads will be put in the circuit board while the leads will be soldered through the wave soldering method. Some components of SMT are put at the bottom of the circuit boards in order to efficiently solder them via wave soldering method as well. With SMT method, solder paste will be deposited through the connection pad and the components are put on the pads. When testing the PCBs, the assembled products are put in a fixture in order to bring electrical power and assess their functions.

Other Important Processes Involved

The active circuit boards will then be put in the “environmental stress system” or ESS chamber to cycle between low and high temperature systems within a specific amount of cycles in order to help identify if the stresses initiate failures on the assembled PCBs. If failures are detected, the boards will be evaluated again to determine the cause. With PCBNet’s expertise, you are guaranteed to receive high functioning printed circuit boards for your electronic needs.
