Description

Ceramic package shell
Technical field
The invention belongs to ceramic packaging technology field, is to be related to a kind of bottom pottery that singly T-shaped lead is drawn more specifically Porcelain package casing.
Background technology
Traditional DIP package casings(DIP is dual inline-pin package abbreviation, also makes dual inline type seal Dress technology)Lead leading-out form is drawn for long side both sides, and it is 2.54mm to commonly use exit pitch, as shown in Figs. 7-9, DIP encapsulation Cpu chip have two row's pins, it is necessary to be inserted on the chip carrier socket with DIP structures.Due to chip area and package area Between ratio it is larger, therefore volume is also larger, and most middle small scale integrated circuits use this packing forms, its pin Number is usually no more than 100.When exit number is more(More than 16 lines), using traditional CDIP(ceramic dual-in- Line package- ceramic double-rows straight cutting encapsulates)Shell draws lead from long side both sides, certainly will cause ceramic package in length side It is oversized upwards, it is unfavorable for shell miniaturization and plate level layout and assembling.
The content of the invention
It is an object of the invention to provide a kind of ceramic package shell, it can solve the problem that in the prior art package casing chi be present Very little big, the inflexible technical problem of Pin arrangement mode.
To achieve the above object, the technical solution adopted by the present invention is:A kind of ceramic package shell, including multilayer pottery are provided Ceramic package, some leads being connected with the ceramic package and the receiving for being arranged at the ceramic package that ceramics is laminated The seal mouth ring of the oral area of chamber, some leads are vertically drawn from the ceramic package surface, and the lead is in institute The surface for stating ceramic package surrounds rectangular configuration, and four of the rectangular configuration in four with the ceramic package respectively one One correspondence, the one end of lead away from the ceramic package described in per one side are connected as a single entity by a connector respectively.
Further, each described lead is respectively arranged with what is flipped over the exit that the ceramic package is connected Bending part.
Further, the both ends of each connector are respectively arranged with first positioning hole.
Further, in lead described in every one side, one second is respectively arranged with two leads at both ends Positioning hole.
Further, in lead described in every one side, the installation of plate level is respectively arranged with two leads at both ends Spacing mark.
Further, the quantity of the lead on relative both sides is identical.
Further, the connector is and the lead material identical hardware.
Further, the width of the lead is between 0.10-0.50mm.
Further, the thickness of the lead is between 0.10-0.30mm.
Further, the pitch of the lead exit be 0.65 mm, 0.80 mm, 1.016 mm, 1.27 mm and Any of 2.54mm.
The beneficial effect of ceramic package shell provided by the invention is:Compared with prior art, ceramic package of the present invention Shell, lead are vertically drawn from a surface of ceramic package, rather than are drawn from the side of ceramic package, lead exit row Row mode is more versatile and flexible, and extraction location can be arranged according to the requirement of client, and because lead is drawn from side, The arrangement mode on ceramic package surface is versatile and flexible, can also reduce the volume of device, realizes device miniaturization, reduces fixing body Product.
