PCBA refers to the complete electronic circuit board after all components have been assembled . It has many benefits that make it a much sought-after element in the communicating and electronics industry.
The PCBA is a complete assembly. You have to assemble the PCB, once it is ready. The assembling requires both passive and active components. The list of these electronic components include-
Resistor
SMD capacitor
Transformer
Diode
ICs
Transmitter
The PCBA electronic components have two types.
1. SMD components: It refers to surface mount devices. You have to use the surface mount technology to install these components on the PCB. You can identify the SMD components by measuring the number of pins in the package.
2.Through-hole components: Thru-hole or through-hole components have leads in them. The leads are inserted through the PCB board surface. You have to drill holes on the PCB surface to insert the thru-hole components into it.
There are two way to assembly of the printed circuit board . one way is You may adopt for automated soldering to mount the electronic components on the PCB. The most popular soldering technology is wave soldering. It is used for the conventional thru-hole components.
Another way widely used soldering technique for PCB components is reflow soldering . It is used for SMD components mostly. You may also use mixed soldering technology. Some expert professionals will use hand soldering too. But it is a quite difficult task.
The assembly of the PCB is completed when the electronic components are welded or assembled on the PCB.
