![]() ![]() ![]() The contrast between empty spaces, traces, and planes is too high in the yellow solder mask. It is to the surprise why designers and engineers do not pick the yellow PCB color. Various colors for choice to meet all kinds of customer’s needsĪ Yellow solder mask also offers excellent contrast between planes, traces, and empty spaces however, the color is unpopular.Excellent mechanical and chemical properties.Besides, the solder mask also has the following functional characteristics: Solder Mask has many functions for example, it prevents solder from bridging between conductors and provides a permanent protective coating for the copper traces and protection against oxidation, avoiding short circuits.Įxactly speaking, a solder mask can also be called the “Protection Layer” of PCBs. Solder mask is a protective coating for the bare PCB board Bare PCB boards are not only to prevent accidental solder bridging as assembly covered with the mask but also protect the board from the environment. This solder resists layer, known as solder mask layer as well. ![]() Except for the connection points for soldering, the whole surface should be covered by solder mask ink. Solder Mask, also called solder resist mask, is generally applied to a printed circuit board (PCB). Testing & Inspection Methods for PCB and PCBA.PCB Manufacturing Capabilities Menu Toggle.
