PCB Assembly Steps: The following is a sample routine for assembling a
mixed technology printed circuit board. Each step will be featured right
here in the weeks to come.
Stencil selection
Screen Printing
SMT part placement
SMT Reflow
Through hole assembly,
Wave and/or hand soldering
Testing
All Assemblies will go through several inspection steps along the way, the testing is the end may be electrical, visual, AOI, or functional testing

Methods Applied for PCB Assembly
Two different approaches are applied to assemble components on the circuit board. They are:
Through-hole technology: This method involves:
the use of pins attached to electrical components that are inserted into the holes on the circuit board.
after proper mounting on the board, pins are soldered to the opposite side in order to fix the component.
the use of through-hole technology was highly popular in the early years for precision.
skilled labor accomplished this as it can solder pins to minute details.
Surface-mount technology (SMT): This relatively modern technology has entirely replaced through-hole method. It involves:
mounting components directly onto the surface of the printed circuit board.
SMT electrical components are smaller in size
Mechanized reflow oven soldering technique is used to fix the components onto the PCB.
The arrival of SMT revolutionized the manufacturing process of PCB assembly by cutting down on both time and cost.
Complex circuits may use a combination of both through-hole and SMT methods in assembling components. This happens because both the techniques have certain specifications which are unique to that process. A combination of both these technologies is known as mixed assembling.
Testing of a PCB assembly
Once the PCB is assembled, it has to be tested in conformity with the quality standards. In times of 'power off status,' PCB assembly is tested for component placement strength of soldering visual and optical inspections and analog signature analysis. When it has 'power on,' it is tested for performance and physical measurements such as voltage and frequency.
