We have established ourselves as a leading manufacturer, supplier, wholesaler, distributor and trader of superior quality FRP Pole Decorative Ball. Surface mount technology (SMT) is a method for constructing electronic circuits in which the components (SMC, or Surface Mounted Components) are mounted directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface mount device or SMD. In the industry it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board.
