Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The design of the SOP8 lead frame structure of many arrangements, the main arrangement problems that will solve exactly between many row's circuit, should reduce the effective area of circuit dispersion as far as possible, thus save encapsulating material, consider reliability during whole piece circuit package again.
The SOP8 lead frame structure of many arrangements of the present embodiment is as Fig. 1, shown in Fig. 2 and Fig. 3, several installation units 2 comprising frame base 1 and be arranged in frame base 1, the length of frame base 1 is 266.466 ± 0.100mm, width is 83 ± 0.050mm, 396 installation units 2 are provided with altogether in frame base 1, described installation unit 2 arranges into 11 rows along the Width of frame base 1, length direction along frame base 1 lines up 36 row, often adjacent two row installation units 2 form a construction unit, in odd number row and even rows, the outer lead pin of adjacent installation unit 2 is intersected with each other staggers, the installation unit 2 in frame base 1 is made to line up the IDF matrix type structure of 11x36, step pitch between adjacent installation unit 2 is 6.436mm, step pitch between adjacent structural units is 16.622mm.In lead frame of the present utility model and current industry, 6 size lead frames arranged contrast, as shown in table 1:
This lead frame of table 1 and existing 6 row lead frame size comparison
| Project | Overall length (mm) | Beam overall (mm) | Only/bar | Area (mm 2/ only) |
| The design's lead frame | 266.466 | 83.00 | 396 | 55.85 |
| Existing 6 row lead frames | 238.00 | 78.00 | 192 | 96.69 |
As can be seen from Table 1, arrange compared with package lead mount structure with existing 6, lead frame described in the utility model, installation unit 2 quantity in every sheet frame base 1 adds 106.25%, and installation unit area list only reduces 42.23%, has saved raw material.
The utility model is furnished with 11 row 36 row installation units 2 in full wafer frame base 1, and the structural installation unit 2 of so every sheet SOP8 package leadframe amounts to 396, can fill 396 circuit.Can calculate by output 8 SOP8 package lead mount structures with every mould, packaged battery way can reach 3168.The production efficiency of the utility model lead frame and 6 row lead frames contrasts as shown in table 2.
This lead frame of table 2 and existing 6 row lead frame production efficiencys contrast
