When you form a production contract with an electronics manufacturer, conformal coating will most likely join the board assembly process. It is getting more and common to coat every type of boards, but those that will certainly be exposed to hazards like dust, moisture, vibration and chemicals should always be coated.
There are various systems of applying the coating that come with different benefits and downsides including different price tags. Some strategies may even slow production because they take longer to complete. Look in your production contract and talk to your manufacturer to get a good appreciation of the technique they use and the reason why they think it is the best one.
Coating after board assembly is generally done in one of four ways. Dipping is a simple way to provide good coverage, but can only be used with types of conformal coating that do not cure and dry fast. Manual spraying is handy for many companies because just about any type of coating can be applied through spraying. Brushing is a rather more time taking process because employees must brush the coating on by hand, and must be sure to provide good coverage. Spraying and dipping are a bit more foolproof as far as coverage goes.
Robotic application involves programmed apparatus that applies the coating where it's required. This sort of application has distinct edges over the other 3 methods. It can be employed with any substances in just about all cases. That suggests a company does not need to leap from one technique to another when using different products.
It is also a selective application, implying the coating goes precisely where it's needed each time with no waste. There's no need for masking off parts that will not be coated, which saves labor, time and money.
Mechanized application and production simply lower expenses by reducing waste and working more efficiently than is humanly possible.
