Difference between pcb's with different color soldermasks

There is a significant difference in function, application scenarios and visual effects of PCBs with different color soldermasks. The following is a detailed description of the various colors of soldermask:

Green Soldermask:

Green is the most common color and is mainly used to protect the circuit board from environmental oxidation and corrosion, to prevent short circuits, and to prevent excessive heat transfer to the board during soldering. The lighter color of green soldermask helps the pads and wiring to be clearly visible for soldering and inspection work.
