PCB Assembly

Production process / Manufacturing step

PCB Assembly (Rigid) is the next stage after fabrication—it’s where the electronic components are mounted onto a rigid PCB to make it a working circuit.

 Steps in Rigid PCB Assembly

1.  Solder Paste Application

  • Solder paste is applied on pads using a stencil.

2. Component Placement

  • Done by automated machines (pick-and-place)
  • Components are placed precisely on the board

3.  Reflow Soldering

  • Board is heated in an oven
  • Solder melts and forms strong electrical connections

4.  Inspection

  • Methods:
    • Visual inspection
    • AOI (Automated Optical Inspection)

5.  Through-Hole Assembly (if needed)

  • Components inserted into drilled holes
  • Soldered using wave soldering or manual soldering

6.  Testing

  • Functional testing (does the circuit work?)
  • Electrical testing

  Types of Assembly

  • SMT (Surface Mount Technology) → components mounted directly on surface
  • THT (Through-Hole Technology) → components inserted into holes
