Be directed to this, also considered the method for subsidiary radiating piece on semi-conductor top, but owing to about 50% of the heat that is discharged is accumulated on the base plate for packaging, so the thermal diffusivity of base plate for packaging still becomes problem.
In addition, in a plurality of surface mounting luminous diodes being used for nearest mobile telephone that button shows etc., exist the most of heat that distributes by photodiode to be accumulated in problem on the substrate.Specifically, for example dispose on being formed with the resin insulating barrier of portion of terminal in light-emitting diode chip for backlight unit, the surface mounting luminous diode of its top by the sealing resin encapsulation of the band lens jacket of holding concurrently, the thermal diffusivity of above-mentioned resin insulating barrier becomes problem.
