Abstract: Panel interlocking means secures together first and second panels in overlapping relationship. The first panel comprises a locking tab struck therefrom adjacent the free edge thereof The locking tab extends away from the free edge of the first panel and defines a first aperture in the first panel. The locking tab has a neck portion hinged at its base to the first panel and terminates in its shoulder portion. The second panel includes a second aperture struck therefrom adjacent the free edge thereof. The second aperture receives the locking tab such that when the panels are locked together, the free edge of the second panel is located along the locking tab between the base of the neck portion and the shoulder portion, and the locking tab is engaged with an edge of the first aperture.

Abstract: An apparatus for making electronic component assembly comprising:a first tape feeder for feeding a supporting tape to an assembly stage,a punching tool for making perforations with a predetermined pitch on said supporting tape,a feeding way for feeding electronic components near said assembly stage at then consecutively pushes said electronic component onto said supporting tape in said assembly stage,a rotating drum having around its outer face a number of projections to engage to said perforations and a number of guiding member to define positions of lead-wires of said electronic components when pushed onto said supporting tape,a second tape feeder for feeding a bonding tape onto said supporting tape at a position after said assembly stage in a manner not to cover said perforations anda bonding roller for pressing to bond said bonding tape onto said supporting roller with said lead-wires inbetween.
