Abstract
A mould forming block for high precision integrated circuit four-side pin in-line package comprises a forming block body, a plurality of runners, a plurality of gates and a plurality of cavities disposed on the forming block body and an injection hole arranged on an upper surface of the forming block body. The injection hole is connected with runners. Every runner is provided with a self-locking runner cored hole. The plurality of gates on the upper surface of the forming block body pass through cavities. Every runner cored hole is provided with an optional self-locking runner core. The mould forming block in the utility model has the advantages of reasonable structure, high package precision, high production efficiency, small production manufacturing time and low cost.
Description
Technical field
The utility model relates to the semiconductor integrated circuit package mould, particularly relates to high-accuracy integrated circuit four side pin straight cutting encapsulating mould forming blocks.
Background technology
The encapsulation of integrated circuit refers to the shell that semiconductor integrated circuit chip is installed.This shell not only plays a part to lay, fix, seal, protect chip and strengthens electric heating property, but also is the bridge of linking up the chip internal world and external circuit.Contact on the chip is wired on the pin of package casing, and these pins connect through the lead in the printed board and other devices again.Therefore, encapsulation plays crucial effects for integrated circuit.Package module exists two big defectives in the prior art, and first mould molding piece can not carry out the selectivity material feeding to bad package module is arranged in carrying out the material feeding process.
The utility model content
In order to solve the technical problem that above-mentioned prior art exists, the utility model provides a kind of can carry out self-locking to bad die cavity module, reduces the high-accuracy integrated circuit four side pin straight cutting encapsulating mould forming blocks of cost waste.
The technical scheme that adopts is:
High-accuracy integrated circuit four side pin straight cutting encapsulating mould forming blocks; Comprise that forming blocks body, forming blocks body are provided with many runners, a plurality of cast gate; Forming blocks body upper surface is provided with material hole, and material hole is connected with runner, and every runner is provided with a self-locking runner cored hole; A plurality of cast gates of forming blocks body upper surface and die cavity connect, selective self-locking runner core of each runner cored hole assembling.
The utlity model has rational in infrastructurely, encapsulation precision is high, and production efficiency is high, production few and low cost and other advantages in man-hour.
