LEAD FRAME |
摘要 |
A lead frame, as one product unit in a multi-row lead frame sharing a partition frame among other lead frames, has a non-mirrorsymmetric pad region and at least one terminal region arranged inside and held to a rectangular outer frame region, which is a part of the partition frame and forms a boundary of the lead frame as a product unit, via respective suspension leads. Only two suspension leads hold the non-mirrorsymmetric pad region to the outer frame region as extending from opposite sides of the outer frame region to the non-mirrorsymmetric pad region, respectively. This structure decreases stress resulting from holding of the non-mirrorsymmetric pad region to the outer frame region and thus can prevent the outer frame region from deformation without widened connecting bars or dambars, which form the outer frame region. |

1. A lead frame that forms one product unit in a multi-row lead frame upon sharing a partition frame among other lead frames as product units, the lead frame comprising:
a non-mirrorsymmetric pad region; and at least one terminal region, wherein the non-mirrorsymmetric pad region and the at least one terminal region are arranged inside and held to a rectangular outer frame region, which is a part of the partition frame and forms a boundary of the lead frame as a product unit, via respective suspension leads, and wherein suspension leads that hold the non-mirrorsymmetric pad region to the rectangular outer frame region consists of two suspension leads, which extend from opposite sides of the rectangular outer frame region to the non-mirrorsymmetric pad region, respectively. |
