Flat metal package is divided into one-piece or multi-piece brazing type.One-piece adopts deep drawing of modes,multi-piece adopts brazing frame and base spearatly processed.The leading method for leads is through sidewall,suitable for surface mount assembly.Usually used in one-piece circuit、hybrid integrated circuits assembly.
Main characteristics
*Package adopts material of kovar or cold rolled steel.The structure of multi-piece is to strengthen thermal conductivity.Base adopts material of WuCu、Oxgyen Free Copper or CRS1010 and etc.
*The height of package adopts customers’ needs.
*Pins are divided into rectangular cross section chemical erosion or round pins based on shape of cross section according to customers’ choice.
*The position of ground pin is determined by customers’ needs.
*Lid is designed fitted the appearance of package.
*Package should be electroplating to get high reliable properity of usage and customer choose package fully plating Au or leads selective plating Au acccording to needs.
*All indexes meet the requirement of GJB548B.

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.
