Abstract: A method for manufacturing a pre-molding leadframe strip with compact components is disclosed. The method forms a leadframe strip with an array of component regions, each component region including two metal parts for using as a chip-attached portion, a wire-bonded portion and two external electrical connection conductors. Next, the leadframe strip is plated with a metal layer having high conductivity and die bonding adhesion. Finally, a pre-molded structure on each of the component regions is formed to surround all the other portions of the leadframe strip with an exception of only the two external electrical connection conductors through a multiplicity of pre-molding processes, each pre-molding process molding the leadframe strip at an interval of one or more than one component regions.

Abstract: A paper punch has a base, two cutters, two articulated linkages and a lever. The base has a top, an open bottom, a cavity, two punch holes and two brackets. The punch holes are defined through the top. The brackets are mounted on the top and each bracket has two guide slots. The cutters are slidably mounted respectively in the brackets and each cutter has a blade. The articulated linkages are pivotally mounted respectively on the brackets and each has a lower link and an upper link. The lower link is mounted pivotally and slidably on a corresponding bracket. The upper link is mounted pivotally on a corresponding lower link. The lever is mounted pivotally on the brackets and is connected pivotally to the upper links of the articulated linkages. The articulated linkages allow a user to press the lever without strenuous effort when punching holes through paper sheets.

Abstract: A stapler has a base, a magazine, a handle assembly and an articulated lever assembly. The base has a stationary bracket and a recoiling tab mounted to the stationary bracket. The magazine is mounted pivotally to the base and has a frame mounted pivotally on the base and a slot defined in the frame. The handle assembly is mounted pivotally to the base and has a handle and a magazine cap mounted pivotally on the base. The articulated lever assembly is mounted pivotally to the handle assembly and the base and has a lever and a link. The lever is mounted pivotally to the base. The link is mounted pivotally between the lever and the handle. The articulated lever assembly allows a user, especially a female or a child to press the stapler without strenuous effort when stapling paper sheets.
