The following are the main steps of the assembly process of PCBs.

  1. Stenciling of Solder Paste

Utilization of a stencil is ensuring soldering paste to be applied to all of the parts where components are to be inserted. The mechanical fixture is utilized for holding the PCB and stencil onto a single place. Soldering paste is then applied at intended areas through an applicator and is spread. After removal of the stencil, soldering paste is leftover from desired locations.

  1. Picking and Placement

A robotic gadget is utilized for picking the components and placing them on to its specific location on the board which is then soldered. The component’s position is to be accurate over soldering paste.

  1. Soldering Reflow

The board is moved over a conveyer belt through the oven. Heating is undergone at high temperatures for melting soldering paste. The next step is cooling down PCB for soldering paste solidification resulting in the strongest joints among the board and components.

  1. Quality Control and Inspection

The PCB is then inspected manually and through machines by inspectors for checking connectivity and floors which may result in malfunctioning. Different inspection methods are used such as optical inspection, manual inspection, and x-ray inspection.
