Depends.
-Most commercial products do not have a conformal coating.
-PCBs of Sanayi, especially military, may need additional protection from moisture and dust.
Manufacture of the PCBs may leave moisture in the fiberglass substrate. That would cause slippy operation towards units. The solution is to bake out the blank PCBs before soldering the parts on and spraying on a conformal coating to seal the analog electronics / PCB. Then calibrate the unit a few days later.

Bir PCB prototipi yapıyorum, Chip Quik'i kullanarak “SMDSWLF.031, Sn96.5/ Ag3.0/ Cu0.5 lehim 2.2% temiz olmayan akı. I find that the black spots appears frequently in larger pads on my board. I wonder if it is because I left the soldering iron more time heating the solder and that burnt the flux. What is that black residue? Is that a sign of a bad joint or maybe bad soldering technique?
PCB tasarım dosyalarımı yakın zamanda bitirdim ve üretim siparişi için üreticiye teslim etmek zorunda kaldım, ancak dosya gizliliğinin sızması konusunda gerçekten endişeleniyorum. Bu durumda nasıl yapabilirim?
My microwave is broken. Should I send it to maintenance or buy a new one? What factors should I consider in this case?
