What are the five main advantages of the conformal coating dip process?

PCBs dipped in DS101 close upFor years, dip coating has been known as the traditional method in applying comformal coating onto circuit boards. It is in this process wherein the circuit is dipped into a conformal coating liquid.

In its simplest form, a board can be dipped manually into a container of conformal coating. However, dip coating is normally done with equipment especially if medium and high volume processing is required.

There are several key variables that control the quality of the coating including

  • Viscosity of the conformal coating
  • Speed of immersion of the circuit board into the conformal coating
  • Dwell time of the circuit board in the conformal coating
  • Withdrawal speed of the board from the conformal coating
  • Critical process controls

There are also five main advantages to the dip coating process. These are:

  • Dipping is a high-speed conformal coating process
  • It is highly repeatable
  • Multiple circuit boards can be coated with dipping
  • Both sides can be coated simultaneously
  • The process requires less operator skill
