ABSTRACT:
A temperature resistant waveguide is mounted to an SMT LED package to provide a complete module that can withstand temperatures found in a solder reflow process without deformation or damage. The waveguide is composed of a high temperature thermoplastic and is coupled to the LED using automated equipment with optical markings for precise positioning and construction. The SMT LED module is automatically located on a printed circuit board and exposed to temperatures for a solder reflow process. The high temperature thermoplastic does not deform during the solder reflow process, thereby providing a robust SMT LED module that can be automatically manufactured and placed on a printed circuit board, without additional steps or human intervention.
