Embodiment Construction
[0025] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. Although the chip-loading area of the infrared end lead frame and the chip-loading area of the photosensitive end lead frame in the claims of the present invention can be cup-shaped or plane, the following examples only use the chip-loading area of the infrared end lead frame as a cup shape, and the photosensitive end lead The slide-loading area of the frame is described as a flat surface.
[0026] refer to figure 1 and figure 2 As shown, the lead frame of the optocoupler is divided into an infrared end lead frame 2 and a photosensitive end lead frame 1, and a plurality of infrared end lead frame units or photosensitive end lead frame units form a row of infrared end lead frames or photosensitive end lead frames. After the package is manufactured, the lead frame pins are punched to separate them into independent components.
