Preventing Corrosion on a Circuit Board

Corrosion on a circuit boardCorrosion is the chemical or electrochemical reaction that happens between the circuit board and its environment. This results in the deterioration of the board and its properties.

Main causes of Corrosion of circuit boards

Corrosion on a PCB can be caused by many factors during the assembly process including the following:

  • Board fabrication
  • Lack of cleanliness in components
  • Assembly equipment
  • Soldering or flux residues
  • Operator handling
  • Incorrect cleaning

Preventing Corrosion

Corrosion can be stopped by doing the following:

  • Cleaning the board properly
  • Controlling the process quality
  • Inspecting thoroughly
  • Ensuring operator cleanliness
  • Choosing the correct manufacturing materials
  • Fine-tuning the solder process
  • Reworking by using low residue wire/flux
