Description
Technical field
The present invention relates to T/R component technology field in Connectors for Active Phased Array Radar, particularly to a kind of LTCC peace
Assembling structure part.
Background technology
Existing LTCC module generally ceramic material is made, it is impossible to use screw to be fixed to structural slab
On, easily LTCC template is damaged by pressure if screw is fixing, therefore generally use conductive silver paste by LTCC template
It is affixed directly on metal structure plate, so when certain LTCC damaged template, it has not been convenient to by LTCC mould
Plate takes off maintenance from structural slab.And the LTCC template being tightly fixed on structural slab by conductive silver paste,
Owing to thermal coefficient of expansion therebetween differs, relatively big (LTCC template is that ceramic material, metal structure plate are
Aluminum alloy materials), under the influence of high temperature or low-temperature working environment, the solder side of the two easily ftractures, and leads
Cause LTCC template to come off from structural slab, or the deformation of LTCC template can not get effectively discharging, LTCC
Easily there is fracture in template, causes LTCC damaged template.
Additionally, in some specific application scenarios, it is desirable to the space shared by T/R assembly is less, and
Under conditions of LTCC module size is certain, can only be to the structure of structural slab and LTCC module and structural slab
Combination improve.
Summary of the invention
