If a printed circuit board (PCB) is being used in a damp environment, such as outside or in a fridge, it is important to protect it. Lacquer is a thin polymer film that is sprayed or painted onto the PCB and components and this protects it against moisture as well as dust, chemicals and temperature fluctuations.
