Abstract

The invention discloses a combined type rib cutting convex mold. The combined type rib cutting convex mold comprises a rib cutting convex mold set unit and a convex mold fixing plate, wherein the rib cutting convex mold set unit mainly comprises a vertical middle rib cutting convex mold, a bottom rib cutting convex mold, a convex mold pressing block and a rectangular convex mold cushion block; the side edges of the middle rib cutting convex mold and the bottom rib cutting convex mold are sequentially connected to form a rectangular cavity; the convex mold pressing block is positioned in the cavity; the upper end of the convex mold pressing block is fixedly connected with the bottom surface of the convex mold cushion block; annular bosses are arranged on the convex mold cushion block; fixed grooves matched with the bosses are formed in the middle rib cutting convex mold and the bottom rib cutting convex mold; the bosses are positioned in the fixed grooves. Compared with the prior art, for the combined type rib cutting convex mold, the production cost of an integrated circuit product is reduced; the production efficiency is improved; the structure of the rib cutting convex mold of the integrated circuit product rib cutting process is improved; the combined type rib cutting convex mold is simple in structure and convenient to process and maintain; the production efficiency is doubled; the mold investment is reduced; the combined type rib cutting convex mold has the necessity of popularization, implementation and application.

Description

technical field [0001] The invention relates to a mold for the rib-cutting process of integrated circuit products, in particular to a combined rib-cutting punch mold. Background technique [0002] The rib cutting process of integrated circuit products is a key follow-up process necessary for the production of integrated circuit packaging. The rapid development of the integrated circuit industry puts forward higher requirements for the design and manufacture of rib cutting molds for integrated circuit products. At present, most of the domestic semiconductor packages are now cutting ribs for integrated circuit products, which are generally completed by two sets of molds for cutting the bottom ribs and cutting the middle ribs; These methods all need to be completed in two pairs of molds, the equipment and labor costs are relatively high, and the production efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a combined rib-...
