Aluminum circuit boards are widely used in LED lighting industry as the good heat dissipation and energy saving. LED light circuit boards always use white solder mask oil because of the good reflective. Our aluminum circuit boards are made of highly reflective white oil, which is 3-5% more reflective than ordinary white oil, whiter and better. Automatic production line for aluminum PCB has been introduced in our factory - fast delivery time, cost down, greatly increased productivity.
