Lead frame assembly and its lead frame

This creation is about a lead frame assembly and its lead frame.

Light-emitting diode devices typically include a light-emitting diode and a lead frame. The lead frame can include two electrodes, and the light emitting diode can be disposed on an electrode and electrically connected to the two electrodes. The light emitting diode device may further comprise a reflective cup formed around the light emitting diode. The reflector can reflect the lateral light of the light-emitting diode outward.

Generally, the fabrication of the LED device is firstly to prepare a lead frame web, wherein the lead frame web can comprise a plurality of arrays of lead frames. The reflector is then correspondingly molded onto the lead frame web. Then, the light emitting diode is fixed to the corresponding lead frame, and is electrically connected to the electrode of the lead frame via a wire. Thereafter, the light-emitting diode is encapsulated in a resin.

In some processes of light emitting diode devices, high density lead frame chips are used. In high-density lead frame webs, the lead frames are densely arranged in small intervals. When the reflector is formed in a high-density lead frame, the reflectors are joined together.

After the resin is packaged with the light-emitting diode, cutting is performed. When cutting, the cutting blade cuts from the metal frame of the lead frame web to the integrated reflector. The lead frame web is made of metal, and the integrated reflector is made of polymer material. Due to the different materials or hardness of metal and polymer materials, different cutting methods are usually required. Under the same cutting method, when the cutting blade cuts a piece of metal and then cuts the polymer material, it is easy to occur. The integrated reflector is bulging or causing problems such as large residual glue or cracking.

In view of the foregoing problems, the present disclosure discloses a new combination of lead frame members and lead frames.
