Abstract
Provided an LED display suitable for attaching to the printed circuit board together with other surface mounted devices by surface mounting process. This LED display may sustain the high temperature of the heating oven without the warping of the reflector. The reflector of the display is made from polycyclohexylene terephalate (PCT) and this reflector is undergone a heat treatment right after the reflector is injecting molded. By this heat treatment, the molecular connections of the plastic material become more perfect. Accordingly, the reflector is inherited with excellent stability and remains this stability during the post processes and at the high temperature of the surface mounting process.
