Resin dispensing apparatus for light emitting device package and method of manufacturing light emitting device package using the same
View Patent ↗There is provided a resin dispensing apparatus for a light emitting device package and a method of manufacturing a light emitting device package using the same. The resin dispensing apparatus includes a resin dispensing part including a resin storage portion filled with a resin therein and a resin discharge portion combined with the resin storage portion and discharging the resin therefrom; a supporting part having a light emitting device package disposed on an upper surface thereof and electrically connected to the light emitting device package; a voltage applying part having both terminals respectively connected to the resin dispensing part and the supporting part to apply a voltage thereto; and a sensing part electrically connected to the resin dispensing part and the supporting part individually and sensing a contact between the resin dispensing part and the light emitting device package with an electrical signal.
1. A method of manufacturing a light emitting device package, the method comprising:
disposing a light emitting device on a supporting part electrically connected to the light emitting device; and
dispensing a resin to the light emitting device using a resin dispensing part electrically connected to the supporting part and discharging the resin therefrom,
wherein the dispensing of the resin includes sensing whether or not the resin dispensing part is in contact with a light emitting device package with an electrical signal.
2. The method of claim 1 , wherein the resin dispensing part includes a resin storage portion filled with the resin and a resin discharge portion combined with the resin storage portion and discharging the resin therefrom, and
the electrical signal is sensed through a contact between the resin discharge portion and the light emitting device.
3. The method of claim 1 , wherein the electrical signal is sensed through a contact between a wire connected to the light emitting device and the resin dispensing part.
4. A method of manufacturing a light emitting device package, the method comprising:
disposing a light emitting device; and
dispensing a resin to the light emitting device using a resin dispensing apparatus,
wherein the dispensing of the resin includes leaving a scratch on a light emitting device package when the resin dispensing apparatus is in contact with the light emitting device package.
5. The method of claim 4 , wherein the resin dispensing apparatus includes a resin discharge portion discharging the resin therefrom, and a contact portion disposed outwardly of the resin discharge portion and having an end thereof corresponding to an end of the resin discharge portion, and
the light emitting device package is scratched by a contact between the contact portion and the light emitting device package.
6. The method of claim 5 , wherein the light emitting device package includes a package body filled with the resin and having a rectangular shape, and
the contact portion has a diameter larger than a width of the package body and smaller than a length of the package body such that the contact portion leaves the scratch on the light emitting device package when being in contact with the package body.
7. The method of claim 5 , wherein the contact portion and the resin discharge portion have the same height, and
the contact portion leaves the scratch on the light emitting device package when the resin discharge portion is injected into the light emitting device package in the dispensing of the resin.
8. The method of claim 5 , further comprising identifying whether the light emitting device package is defective or not depending on the scratch left on the light emitting device package.
