Abstract
An electronic device comprises a carrier, a leadframe, a package body and a plurality of electronic components. The carrier has an open top surface, a closed bottom surface and sidewalls extending between the closed bottom surface and the open top surface. The carrier has a circular cavity in its open top surface extending toward the closed bottom surface. The carrier includes a leadframe including a die pad and a plurality of leads. The leads are physically isolated from the die pad by at least one gap. The package body partially encapsulates the leadframe such that a portion of an upper surface of the die pad and a portion of each of the leads are exposed from the package body. The exposed portions of the leads are arranged radially along the die pad. The electronic components are disposed on the die pad.
Claims26
An electronic device, comprising:
- a carrier having an open top surface, a closed bottom surface and sidewalls extending between the closed bottom surface and the open top surface, the carrier having a circular cavity in its open top surface extending toward the closed bottom surface, the carrier including:
- a leadframe including a die pad and a plurality of leads, the leads being physically isolated from the die pad by at least one gap;
- a package body having a sidewall and partially encapsulating the leadframe such that a portion of an upper surface of the die pad and a portion of each of the leads are exposed from the package body, wherein the exposed portions of the leads are arranged radially along the die pad;
- and
- a plurality of electronic components disposed on the die pad and including a controller and an emitter,
- wherein the sidewall of the package body defines a recess that opens to the circular cavity, and a portion of the die pad extends within the recess, and
- the die pad comprises a central portion on which the controller is disposed and an edge portion on which the emitter is disposed.
An electronic device comprising:
- a controller,
- an emitter,
- a leadframe including a die pad and a plurality of leads, the leads being physically isolated from the die pad by at least one gap;
- and
- a package body partially encapsulating the leadframe such that a portion of an upper surface of the die pad and a portion of each of the leads are exposed from the package body, the package body having an open top surface, a closed bottom surface and sidewalls extending between the closed bottom surface and the open top surface, the package body having a circular cavity in its open top surface extending toward the closed bottom surface, the exposed portions of the leads arranged radially along the die pad,
- wherein at least one of the sidewalls of the package body defines a recess that opens to the circular cavity, and a portion of the die pad extends within the recess, and
- the die pad comprises a central portion on which the controller is disposed and an edge portion on which the emitter is disposed.
An electronic module, comprising:
- a first carrier including a plurality of packages disposed thereon, each package comprising:
- a second carrier having an open top surface, a closed bottom surface and sidewalls extending between the closed bottom surface and the open top surface, the second carrier having a circular cavity in its open top surface extending toward the closed bottom surface, the second carrier including:
- a leadframe including a die pad and a plurality of leads, the leads being physically isolated from the die pad by at least one gap;
- a package body having a sidewall and partially encapsulating the leadframe such that a portion of an upper surface of the die pad and a portion of each of the leads are exposed from the package body, wherein the exposed portions of the leads are arranged radially along the die pad, and wherein the sidewall of the package body defines a recess that opens to the circular cavity, and a portion of the die pad extends within the recess;
- and
- a plurality of electronic components disposed on the die pad and including a controller and an emitter;
- and
- a case covering the packages,
- wherein the die pad comprises a central portion on which the controller is disposed and an edge portion on which the emitter is disposed.
