Abstract:
A lead frame constitutes a product unit in a multi-row lead frame and has a dam bar and a lead connected together. The dam bar has a first site where connection is made with the lead and a second site adjoining the first site without connection with the lead. A predetermined range in the lead near the connecting portion with the dam bar and the second site in the dam bar have a plate thickness smaller than that of the first site having a same plate thickness as a metal plate as a material from which the dam bar and the lead are made. The lead frame is usable irrespective of width of leads to be cut, allows a high degree of freedom in design, facilitates cutting with a reduced volume of a metal, and is capable of inhibiting deformation of long and thin or cranked leads and dam bars.

Claim (Index 1):
A lead frame constituting a product unit in a multi-row lead frame and having, at least,\n a dam bar with a plate thickness, at a predetermined position thereof, smaller than a plate thickness of a metal plate forming a base material of the lead frame, and a lead connected with the dam bar and having a plate thickness, in a predetermined range from an end portion thereof at which connection is made with the dam bar, smaller than the plate thickness of the metal plate, wherein a first site, which is defined as surrounded by sides of the dam bar along a width direction of the lead at the end portion thereof at which connection is made with the dam bar and sides of the dam bar along a width direction thereof, has a same plate thickness as the plate thickness of the metal plate, and a second site, which adjoins the first site in the dam bar and is not connected with the lead, has a plate thickness smaller than the plate thickness of the metal plate.
