A solder mask acts as your FPC’s primary protector against corrosion and oxidation. It affects the FPC quality by preventing performance degradation and the shortening of an electronic’s operational lifespan. More importantly, a solder mask creates a barrier between soldered joints and other conductive aspects of the FPC during assembly, thereby preventing the formation of solder bridges.  

You will rarely see solder masks on hand-made circuits, but they are always present in mass-assembled FPCs, soldered using machines, like solder-baths. FPC supplier will sold the solder mask is a separate FPC layer, just like the copper and silkscreen layers.
