Factory best selling Smt Microwave Device Packages - The Platform Package – Jitai Detail:

Main products include metal package for hybrid integrated circuits, opto-electronic components, microwave components, wave filter components, sensor components and high-power devices. The products are applicable in such areas as aviation, aerospace, electronics and communication devices for military and commerciality. Company has undertaken the ministerial level scientific research projects, and recognized by users.


Packages are made up by mechanically pressing for platform packages,it has high efficiency suitable for bulk production.Leads are leading out from buttom by Plug-In usually shown DIP or Quad Inline suitable for Plug-In assembly.Usually used in thick or thin Hybrid Integrated Circuit assembly.
Main characteristics:
*Leads adopt kovar material,packages adopt kovar,4J42 or CRS1010 material,having high reliablity.
*Lid adopts percussion welding ,tin welding or laser welding.
Leads are cyclinder straight leads.Bonding leads should choose cyclinder or nailhead pins per customers’ needs.
*The layout of leads usually adopt DIP or Quad Inline it can design per customers’ needs.
*The ground pin of package is determined by customer.
*The design of cap should fit the package per package dimension.
*Customer should choose package fully plating Au or leads selective plating Au.
*All indexes should meet requirement of GJB548B.

Plug-In Sidewall Package23

1.Bases are 4J29 FeNiCo alloy or CRS1010,composition and property of 4J29 should meet GBn97-1987 standard,CRS1010 composition and property should meet GB/T699-1999
2.Pins are 4J29 FeNiCo alloy or 4J50、4J50 copper cored alloy,composition and property
of 4J29 should meet GBn97-1987 standard,composition and property of 4J50 should meet
GBn103-1987 standard.
3.Glass insulators are BH series、DM-305 or Elan#13. Composition and property of BH series
Should meet technical data of ratio for BH series in NEG company,composition and property of
DM-305 should meet SJ/T10587.1-97 requirement.
4.Cap is 4J42 FeNi alloy,its composition and property should meet GBn103-1987 standard.
5.Braze is HlAgCu28,its composition and property should meet GB/T10046-2008 standard.

Third Part:Range of design for dimension of package
There is the range of design for Plug-In Sidewall Metal in our company currently see as below:

Process Method Material Of Package Outline Of Package Shape Of Package Depth Of Package Sealing Thickness

One-Piece CNC milling


13.5*12.7min 118*90 max














































Deep Drawn


12.7*12.7min 59.24*59.24max




Fourth Part The principle of design for mode
1.The selection of material for mode
Due to the graphite mode is high temperature resistance,low thermal expansion and neither immerse glass
nor metal,easy to process,its high pure graphite are selected as mode material.
2.The selection of structure for graphite
The series of platform metal package mainly has reverse sintering one formation,it can be flexibly used according to the characteristics of its structures.
3.The principle of design for reverse mode
Reverse sintering should guarantee the consistence for height of bonding surface of inner pin,mainly uses
the whole boat sintering.

The selection of material for lid
Paralle Sealing Welding:4J42
Laser Welding :4J42,4J29,CRS1010;Stainless Steel,AlSi
Screw Mounting:4J42,4J29,CRS1010,Stainless Steel,Aluminum alloy

The design of dimension for structure
3.1:One-piece cnc milling structure
3.2:One-piece deep drawn structure
3.3Separated bodies brazing structure
There are one-piece base and inlaid base structures,it is probably to change the material of base to Cu、WuCu、Dimanond braze and so on material to highly increase the thermal conductivity of package.

The principle of part components.
Flat package adopts lead with shape of cyclinder,rectangle,flattened,bent.Here is a simple introduction for special leads:
The category of flattened metal leads
1.Rectangle Leads
The rectangle leads are chemical etching leads with normal cross scetion0.3mm*0.4mm
2.Flattened Leads
It is processed by flattening the cyclinder straight leads.
3.Bent Leads
According to shape of bending,bent leads are divided into rectangle bent、Z shape bent.According to the cross section of leads,bent leads also divided into cyclinder bent ,rectangle bent.Sometimes we could design the bent flattened leads per customers’s needs of usage.
The design for leads of flat package is Z shape bent leads,leads can choose cyclinder or rectangle leads with diameter≤0.8mm(diameter>0.8mm,it couldnot be bent with two curves).
The design for power housing is mostly rectangle bent leads,and leads are cyclinder.
