Hi
I have a sharp Inverter AC and am using it for the last 3 years but recently I have heard that many PCB have blown as we have a big drainage near our house which when corrodes the copper, PCB blew away and after that its repair is very costly.
I have read that spraying anti corrosion spray on AC PCBs help them to stay longer and delay corrosion which is done due to sea, moisture/humidity and corrosion due to bad smells of drainage systems.
Corrosion is like an atom bomb for inverter ACs as nobody knows when it will explode and destroy the PCB of the AC. For protecting the PCBs and similar components, anti corrosion spray or Conformal Coating or Clear Lacquer is used. I want to know the following:
1. Which one of these or any other is better for protecting PCBs?
2. Are there any disadvantages of using these sprays?
3. How can we use these sprays on PCBs?
4. What type of cleaning of PCBs should be done beforehand of using these sprays?
5. Precautions needed?
Has anybody used any such sprays and if yes, how long it was effective?
Regards
