Abstract:
A method of manufacturing a package, the method comprising the steps of: preparing a resin compact having a recess, and including a pair of leads arranged at a bottom surface of the recess, a first resin body forming a lateral wall of the recess, and a second resin body arranged between the pair of leads; forming a reflective film entirely on at least the bottom surface of the recess and an inner surface of the lateral wall of the recess; and removing the reflective film formed on the pair of leads in the recess in the resin compact on which the reflective film has been formed.
Abstract:
A method for manufacturing a light emitting device includes providing a package having a recess in which a light emitting element is disposed. A translucent sealing material is provided in the recess to encapsulate the light emitting element. A film is provided on the translucent sealing material. The film includes a translucent base material and particles disposed in the translucent base material. The film has a contact surface to contact the translucent sealing material and an outer surface opposite to the contact surface. Abrasive is blasted onto the outer surface of the film to roughen the outer surface so as to expose at least one of the particles.
Abstract:
A package for mounting a light emitting element includes: a first lead electrode having, in a plan view, a first region, a second region surrounding a periphery of the first region having a width of 110 μm or more and a thickness greater than that of the first region, and a third region partially surrounding a periphery of the second region and having a thickness smaller than that of the second region; a second lead electrode spaced apart from the first lead electrode; and a resin molded body fixing a portion of each of the first and second lead electrodes. A portion of each of the first and second lead electrodes and a portion of the resin molded body exposed therebetween form a bottom surface of a recess.
Abstract:
A light emitting device includes a package including a resin member having an inner side surface defining a recess, and a lead frame supported by the resin member and arranged at a bottom surface of the recess; and a light emitting element electrically connected to the lead frame.
