What is Electronic Circuit Coating (Conformal Coating)?
Electronic circuit coating is a method applied to the printed circuit board (PCB) to protect circuit boards and circuit elements against environmental conditions (humidity, dust, vibration, etc.) and to prevent corrosion.
So what is a PCB? PCB or Printed Circuit Board (printed circuit board) is called the plates on which the electronic circuit elements are placed and the electrical connection between these elements is provided by means of copper surfaces.
Briefly, PCBs have two important purposes;
1) Keeping electronic components together,
2) To provide electrical connection between components.
Protective coatings are designed to protect solder joints, leads of electronic circuit components, exposed traces and other metallized areas from corrosion, the conformal protective coating process extends the working life of the PCB.
To examine the methods applied in the conformal protective coating process, you can review our blog post “Protection of Electronic Cards Against Environmental Conditions”.
Why is the Use of Electronic Circuit Covering Important?
Moisture, dust, vibration, high temperature, etc. formed in the working environments where circuit boards are used. Its efficiency may decrease compared to the first use due to external factors. It is important to protect the printed circuit boards and components used in such environments. Ultimately, in order for circuit boards to work efficiently and to protect them from environmental conditions, they must be used with a protective coating process.
What are the Usage Areas of Electronic Circuit Coating?
Since the electronics industry has a rapidly developing structure in the world, the use of electronic circuit coatings in the industry is increasing in order to protect the efficiency of the circuit boards from the factors that will adversely affect it.
Electronic circuit coating chemicals are also used to prevent copying of circuit board designs. Conformal protective coatings have been developed especially for automotive, defense industry, aerospace, marine, lighting, industrial industry applications.
