The retail price of Aluminum LED lights has dropped dramatically in recent years, while the energy efficiency and brightness of LED lights have improved. These technological advances have led some to predict annual growth of 45% over the next five years. With the development of the LED industry, the demand for LED PCBS and solder masks is also increasing. Solder shield is a protective coating applied to exposed printed circuit boards. The exposed PCB board is covered with a mask to prevent accidental solder bridging during PCB assembly and to protect the PCB from the environment. Solder masks are traditionally green, and are expected to withstand the high temperatures that occur in reflow soldering, as different colors such as blue, red, or black will occasionally appear. Increased production of Hitch Aluminum LED PCB requires increased whiteness and color stability of the mask. Aluminum LED PCB commonly used LPI welding color is white and black, of which white welding color is the mos
