Embodiment 1

[0025] Refer to the attached figure 2 , the power type LED lead frame sheet of the present invention includes a lead frame 6, a frame 7 and a connecting rib 3, wherein a process hole 1 is arranged on the frame corresponding to the longitudinal centerline of the lead frame, and a process gap 2 is arranged on the outside thereof, and the connecting rib and the lead wire A horizontal connecting rib 5 is arranged between the frame pins, the step distance is 9.5 mm, and the width of the connecting rib 3 is 1.45 mm, and it is between the frame 7 and the horizontal connecting rib 5 on the corresponding side; The rib length is 1.05mm.

[0026] In order to facilitate identification of the processing orientation of the lead frame sheet in subsequent processing steps, an auxiliary process hole 8 is provided on one of the frames 7 corresponding to the ribs 3 , and the processing orientation can be identified according to the auxiliary process control.

[0027] Because of the addition of...

Embodiment 2

[0029] Refer to the attached figure 2 , LED lead frame sheet of the present invention, it is with respect to embodiment 1, and step distance adopts 9.6mm, and in fact the optimal solution of the present invention is that step distance adopts 9.525mm, and step distance cannot be too small, if too small, then finally every The design of the lead frame slitting die will be very difficult, and the arrangement and design of the connecting ribs and horizontal connecting ribs will also be difficult. The strength cannot be guaranteed, and the stiffness is relatively secondary here. However, if the step distance is too large, the structural waste will inevitably increase, which is not conducive to energy saving and consumption reduction, saving raw materials. Corresponding to the step distance of 9.6mm, the width of the connecting rib is 1.55mm, and the width of the connecting rib should consider the stiffness and strength requirements of the lead frame sheet, especially the rigidity....

Embodiment 3

[0031] Refer to the attached Figure 4, this embodiment is mainly aimed at the SnapLED type lead frame sheet, because the structural strength of the lead frame itself is relatively high, so the setting of the connecting ribs is narrower than that of 1 and 2 in the implementation, but in order to balance the influence of the additional stress on the lead frame, The connecting rib part between the two horizontal connecting ribs is retained. Its step distance is exactly the same as that of Embodiments 1 and 2, which is 9.5 mm to 9.6 mm, and the width of the connecting rib 3 between the frame 6 and the horizontal connecting rib 5 is 0.95 mm to 1.05 mm, and it is between the The width of the portion between the two horizontal connecting ribs 5 is 0.48 mm to 0.5 mm; the length of the horizontal connecting ribs is 1.23 mm to 1.33 mm, and the selection of the length and width of the connecting ribs is also consistent with the above-mentioned embodiment.

Abstract

The invention discloses a power type LED lead frame sheet and belongs to the middle piece in the LED lead frame processing technique. The invention further relates to the processing technology of the power type LED lead frame sheet. The power type LED lead frame sheet includes a lead frame, a frame and a bracing member, wherein a fabrication hole is formed on the frame corresponding to the lead frame longitudinal midline, a fabrication nick is disposed on the outer side thereof, a transverse bracing member is arranged between the bracing member and a pin of the lead frame, the step pitch ranges from 9.5mm to 9.6mm, the width of the bracing member ranges from 1.45mm to 1.55mm, the bracing member is arranged between the frame and the transverse bracing member on the corresponding side, and the length of the transverse bracing member ranges from 1.05mm to 1.30mm. The invention provides the power type LED lead frame sheet with less structural waste, low energy consumption in processing and high production efficiency.

Description

(1) Technical field [0001] The invention relates to a power type LED lead frame sheet, which belongs to the processing technology middleware of the LED lead frame, and also relates to the processing technology of the power type LED lead frame sheet. (2) Background technology [0002] LED light-emitting products have outstanding advantages such as energy saving, short light response time, long life, and small size. LED lighting has a very bright future and a wide range of applications. It has been widely used in automotive lighting, indicator lighting and decorative lighting. Power LED lead frame is a supporting part of high-grade LED, and the demand in the international market is increasing day by day. There are mainly two methods for manufacturing lead frames for small devices such as LEDs, one is to manufacture lead frames by etching, and the other is to manufacture lead frames by stamping. For the latter, because it is directly formed by cold stamping, it has the charac...
