Abstract

The invention relates to a 100W solid-state relay lead frame, which comprises an edge rib. The edge rib is connected with a first pin, a second pin, a third pin, a fourth pin and a fifth pin in sequence from right to left through connecting ribs; the lower ends of the first pin, the second pin, the third pin, the fourth pin and the fifth pin are connected with the edge rib; the upper end of the first pin is connected with a first slide island with a larger area; the first slide island is made of a thick copper strip, and the first slide island is provided with a silver plating area for mounting a switch chip; the upper ends of the adjacent third pin and fourth pin are connected with a second slide island and a third slide island respectively; the second slide island and the third slide island are respectively provided with a silver plating area used for installing a coupling chip and a silver plating area used for installing a photosensitive element; and the upper end of the second pinand the upper end of the fifth pin are respectively provided with a silver plating area. The 100W solid-state relay lead frame meets the requirement for high-power output of products and is high in production efficiency and yield.

Description

technical field [0001] The invention relates to a lead frame, in particular to a 100W solid state relay lead frame. Background technique [0002] As one of the most critical components in semiconductor components and integrated circuit packaging, lead frame plays a role in supporting chips, signal distribution and connecting external circuits. In the existing technology, the insulation voltage of the input terminal and the coupling terminal is low, it is difficult to form glue during the production process, and the yield is low; in addition, the product has a small heat capacity and poor heat dissipation, and the product cannot meet the requirements of high-power use when it is used at the end. Contents of the invention [0003] In view of the above shortcomings, the applicant has conducted research and improvement, and provides a 100W solid state relay lead frame. [0004] The technical scheme adopted in the present invention is as follows: [0005] A 100W solid-state r...
