Printed circuit board assembly, also known as PCBA, is the process of soldering or assembly of electronic components to a PCB or printed circuit board. A circuit board prior to assembly of electronic components is known as PCB. Once electronic components are soldered, the board is called Printed Circuit Assembly (PCA) or Printed Circuit Board Assembly (PCBA).
Manufacturing printed circuit boards assembly involve electronic components need to be soldered onto it before it can be used in any electronic equipment or gadget. This assembly of electronic components depends on type of circuit board, type of electronic components and purpose of the circuit board.

Following electronics parts and consumables are needed for PCB assembly –

  • Printed Circuit Board
  • Electronic components
  • Soldering materials including solder wire, solder paste, solder bar, solder preforms (depending on the type of soldering to be done)
  • Soldering flux
  • Soldering equipments including soldering station, wave soldering machine, SMT equipment, inspection and testing equipment etc.

Once all of the above equipment, electronic parts and all raw materials are arranged, it is time to start the assembly process.
