Abstract
The utility model provides a shell that is used for non - refrigeration focal plane detector metal package, relates to infrared detector, the especially convenient a shell that is used for non - refrigeration focal plane detector metal package of encapsulation. The utility model discloses a shell that is used for non - refrigeration focal plane detector metal package, this shell of its characterized in that includes casing, metal pad and metal pin -attached, and the casing is squarely and open -top, and the metal pad is two, sets up on casing two relative lateral walls respectively, it is fixed that metal pin -attached passes the metal pad, and the one end setting is inside the casing, and other end setting is outside at the metal pad. The utility model discloses a shell that is used for non - refrigeration focal plane detector metal package, simple structure, the design science, convenient to use through metal pad stationary metal pin, the displacement of effectively having stopped metal pin -attached, adopts exhaust copper pipe to exhaust fast simultaneously, realizes vacuum environment, and packing speed is fast, and is efficient.
Description
Technical field
This utility model is related to Infrared Detectorss, and especially a kind of encapsulation is convenient a kind of for non-refrigeration focal surface detection
The shell of device Metal Packaging.
Background technology
In recent years, with the continuous progress of non-refrigeration focal surface Infrared Detectorss technology and being gradually reduced for manufacturing cost,
Its cost performance fast lifting, is that the mass market application for promoting non-refrigeration focal surface Infrared Detectorss creates good condition.
Non-refrigeration focal surface Infrared Detectorss are mainly made up of parts such as reading circuit, detector pixel, getter, encapsulation.Encapsulation
Form directly determines performance, reliability and the price of non-refrigeration focal surface infrared detector module.
At present, the packing forms of the main product on market are mainly Metal Packaging, typically fix detector chip
In an open-topped square casing, the then welding metal pin on chip, and metal pins are drawn into hull outside,
Then infrared window is welded at the opening of housing, then enclosure interior is evacuated, complete encapsulation.
But in encapsulation process, metal pins position is difficult to fix, during later stage use, easily produce metal and draw
Foot displacement, is caused metal pins to be departed from chip or the sealing of tamper detection device, not only have impact on detector using effect,
Even cause detector to damage, and in vacuum, processing step is complicated, packaging efficiency is not high.
The content of the invention
To be solved in the utility model is exactly that existing non-refrigeration focal surface Infrared Detectorss packaging technology is complicated, and the later stage makes
With during, metal pins are susceptible to displacement and even depart from, and affect detector using the problem even damaged, there is provided Yi Zhongfeng
A kind of convenient shell for uncooled fpa detector Metal Packaging of dress.
A kind of shell for uncooled fpa detector Metal Packaging of the present utility model, it is characterised in that the shell
Including housing, metal pad and metal pins, housing is square and open top, and metal pad is two pieces, is separately positioned on shell
On two side walls of body phase pair；Metal pins are fixed through metal pad, and one end is arranged on enclosure interior, and the other end is arranged on gold
Outside category pad.
Aerofluxuss copper pipe is additionally provided with described housing, aerofluxuss copper pipe is connected with the one of side wall of housing, and encapsulation is completed
Afterwards, enclosure interior air is excluded by aerofluxuss copper pipe so that the enclosure interior after encapsulation is in vacuum state.
Described metal pins are two groups, are separately fixed at per group on one piece of metal pad, and every group of metal pins are by gold
Silk is connected with chip.
When in use, first detector chip is welded on housing inner bottom part, the pin of chip both sides respectively with metal
Pin belongs to side together, and then the two ends of spun gold are respectively welded on chip pin and metal pins, and chip is by spun gold and gold
Category pin connection, is realized being electrically connected with outside by metal pins, infrared window is welded on opening for case top again afterwards
At mouthful, the evacuating air in housing is artificially realized into vacuum environment using aerofluxuss copper pipe finally, by the closing of aerofluxuss copper pipe be afterwards
The vacuum state of enclosure interior can be ensured；As metal pins are welded on metal pad, the steadiness of its connection is improve,
The offset phenomena produced during effectively preventing use simultaneously.
A kind of shell for uncooled fpa detector Metal Packaging of the present utility model, simple structure, design department
Learn, it is easy to use, metal pins are fixed by metal pad, has effectively prevented the displacement of metal pins, while adopting aerofluxuss copper
Pipe carries out Quick air-discharge, realizes vacuum environment, and package speed is fast, efficiency high.
Description of the drawings
Fig. 1 is this utility model structural representation.
Wherein, housing 1, metal pad 2, metal pins 3, aerofluxuss copper pipe 4.
Specific embodiment
Embodiment 1：A kind of shell for uncooled fpa detector Metal Packaging, including housing 1, metal pad 2
With metal pins 3, housing 1 is square and open top, and metal pad 2 is two pieces, is separately positioned on two relative sides of housing 1
On wall；Metal pins 3 are fixed through metal pad 2, and one end is arranged on inside housing 1, and the other end is arranged on outside metal pad 2
Portion.Aerofluxuss copper pipe 4 is additionally provided with housing 1, aerofluxuss copper pipe 4 is connected with 1 one of side wall of housing, after the completion of encapsulation, is passed through
Aerofluxuss copper pipe 4 excludes 1 inner air of housing so that be in vacuum state inside the housing 1 after encapsulation.Metal pins 3 are two groups, often
Group is separately fixed on one piece of metal pad 2, and every group of metal pins 3 are connected with chip by spun gold.
When in use, first detector chip is welded on 1 inner bottom part of housing, the pin of chip both sides respectively with metal
Pin 3 belongs to side together, and then the two ends of spun gold are respectively welded on chip pin and metal pins 3, chip by spun gold with
Metal pins 3 connect, and realize being electrically connected with outside by metal pins 3, again infrared window are welded at the top of housing 1 afterwards
Opening at, the evacuating air in housing 1 is artificially realized into vacuum environment using aerofluxuss copper pipe 4 finally, afterwards by aerofluxuss copper pipe
4 closings can ensure the vacuum state inside housing 1；As metal pins 3 are welded on metal pad 2, its company is improve
The steadiness for connecing, while the offset phenomena produced during effectively preventing use.
