A fabrication method of a side-view type light emitting apparatus comprising:
- sandwiching
- first inner and outer lead portions of a first lead frame and second inner and outer lead portions of a second lead frame by an upper die and a lower die,
- leaving a space between the upper and lower die with a concave shape tapered to become smaller towards a bottom face positioned over the first and second inner lead portions;
- injecting a thermosetting resin
- containing a filler or a light diffusion agent from a gate disposed in a first side face of the upper die into and filling the space between the upper die and the lower die when the upper die is engaged with the lower die;
- heating up the injected thermosetting resin to mold a first resin molding body on top and bottom sides of the first and second inner lead portions,
- the first molding body having a concave portion shaped by the concave shape;
- mounting a light emitting device
- on the first lead frame within the concave portion after at least the upper die is released from the injected thermosetting resin;
- electrically connecting
- a first electrode of the light emitting device to the first lead frame and
- a second electrode of the light emitting device to the second lead frame;
- filling the concave portion of the first resin molding body with a second thermosetting resin where the light emitting device is mounted;
- heating up the second thermosetting resin to mold a second resin molding body;
- and
- bending the first and second lead frames;
- wherein the first resin molding body comprises
- a top surface including an oblong, ellipsoid, or rectangular opening of the concave portion and being substantially a rectangle,
- first and second short side faces perpendicular to the top surface with respective first and second short edges, and
- first and second long side faces perpendicular to the top surface with respective first and second long edges;
- wherein
- the first and second short edges and the first and second long edges form a perimeter of the top surface, and
- the first short side face is formed adjacent to the first side face of the upper die;
- wherein
- a first width of the top surface between the first short edge and the opening of the concave portion is greater than a second width of the top surface between the first long edge and the opening of the concave portion, and
- the second width is not more than 0.2 mm;
- and
- wherein the bending is performed such that
- at least a portion of the second outer lead portion
- is attached to the first short side face and the first long side face and
- extends towards the first short edge to be flush with the top surface, and
- at least a portion of the first outer lead portion
- is attached to the second short side face and
- extends towards the second short edge to be flush with the to surface.
