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 2):
A method for manufacturing a lead frame constituting a product unit in a multi-row lead frame and having, at least, 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,\n comprising subjecting the metal plate to half-etching treatment with a predetermined pattern from at least one side of the metal plate, to thereby form 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, having the 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, having a plate thickness smaller than the plate thickness of the metal plate.
