Abstract:
1. A surface mounting LED substrate for use in production of multi-faced surface mounting LEDs and including a plurality of LED chips adjacent the substrate at a certain interval and sealed in a sealing resin, the surface mounting LED substrate comprising: a substrate layer having an LED chip mounting upper surface, a lower surface spaced from the LED chip mounting upper surface, and a first side surface extending from the LED chip mounting upper surface to the lower surface, and the substrate layer has a first substrate edge located between the first side surface and the lower surface; a conductor pattern having an upper portion formed adjacent to the LED chip mounting upper surface, a lower portion formed adjacent the lower surface, and a side portion, the lower portion includes an underside surface that faces away from the lower surface of the substrate and the side portion is formed adjacent to the first side surface and extends from the upper portion to the lower portion, and the side portion includes an outer surface, and the conductor pattern has a first conductor edge located between the underside surface of the lower portion and the outer surface of the side portion and located along with the first substrate edge; and a resist layer formed on the underside surface of the lower portion of the conductor pattern and formed to reach the first conductor edge to form a side surface of the resist layer such that the first conductor edge, the first substrate edge, and the side surface of the resist layer are substantially coplanar.
