Abstract
Photomultiplier tubes composite packaging method is as follows:-welding the platen and the photomultiplier tube; reconciling epoxy glue on a clean metal plate; put a layer of epoxy glue on the components at the platen surface and photomultiplier tube pin the surface evenly , curing; photomultiplier tubes will be installed metal; reconcile good insulating silicone rubber, metal evenly injected into the crust, curing. The epoxy resin adhesive can be described in JC - 311-type adhesive. This invention provides a method to prevent the flexible silicone rubber bubbling around the platen and the surrounding components in the process of curing the photomultiplier tube metal pins; it also eliminates discharge, fire fighting phenomenon and effectively prevents detection equipment being damaged.
Description
Technical field
The method for packing and the technology that the present invention relates to the photomultiplier in a kind of space astronomy instrument and divide the components and parts in the pressing plate.
Background technology
In many space astronomy detection instruments, high energy particle detection instrument, the faint fluorescence that uses photomultiplier to catch various crystal generations is transformed into photoelectron, becomes a recordable electric impulse signal through repeatedly doubling then.The stability of photomultiplier work is directly connected to the quality of instrument performance.
The purpose of photomultiplier encapsulation is: can not produce mechanical failure in the process of satellites transmits.In hypobaric gas discharge phenomenon can not take place, to guarantee the detector operate as normal.
Normally used encapsulating material is an elastic silicone rubber produced in USA, and title is: SILICONEELASTOMER KIT
Elastic silicone rubber can play three effects:
1, shockproof, the glass bulb of protection photomultiplier can not shattered;
2, play insulation;
3, guarantee the coupling gap of photoelectric tube and crystal;
Use the encapsulation of elastic silicone rubber to photomultiplier, often the problem that occurs is: elastic silicone rubber is in the process of solidifying, sometimes around the metal pin of photomultiplier and produce bubble around the dividing potential drop board component.When environment became vacuum by normal pressure, bubble can be broken and form local low pressure, just produces discharge, spark phenomenon, and detection instrument is damaged.
Summary of the invention
In order to overcome the problems referred to above of prior art, the purpose of this invention is to provide a kind of composite packaging method of photomultiplier.This method can prevent elastic silicone rubber in the process of solidifying around the metal pin of photomultiplier and produce bubble around the dividing potential drop board component; And then eliminate discharge, spark phenomenon, prevent that detection instrument is damaged.
A kind of composite packaging method of photomultiplier, step is as follows:
To divide pressing plate and photomultiplier to weld;
It is stand-by to raise the epoxide-resin glue of becoming reconciled at clean metallic plate;
On dividing potential drop board component surface and photomultiplier pin surface be coated with the last layer epoxide-resin glue equably, solidify;
With the photomultiplier metal shell of packing into;
Be in harmonious proportion electrically insulating silicone rubber, be injected into equably in the Can, solidified.
The application's prioritization scheme is recommended a kind of solidification intensity height, the epoxide-resin glue of good insulation preformance.The name of glue is called JC-311 type adhesive.
Simultaneously, prioritization scheme also can increase some steps, increases some concrete data demands in some step, and the concrete steps operation of prioritization scheme is:
With the clean photomultiplier of alcohol wash;
The photomultiplier metal shell that cleans up encapsulation usefulness is stand-by;
Totally divide pressing plate and components and parts with alcohol wash, dry with hair-dryer;
To divide pressing plate and photomultiplier to weld;
Stand-by by being in harmonious proportion JC-311 type adhesive at 1: 1 on clean metallic plate;
Check the solder joint that divides between pressing plate and the photomultiplier pin;
On dividing potential drop board component surface and photomultiplier pin surface be coated with last layer JC-311 type glue equably, under room temperature 20 degrees celsius, solidified 24 hours;
Check whether each components and parts and photomultiplier pin have the place of the gluing of not being coated with, and carry out secondary and mend glue;
Mend behind the glue 20 degrees centigrade of cold curings 24 hours, the metal shell that photomultiplier is packed into and cleaned up;
By being in harmonious proportion electrically insulating silicone rubber at 1: 1, be injected into equably in the Can, under the condition of 18 degrees centigrade of room temperatures, solidified 24 hours.
Method provided by the invention can prevent elastic silicone rubber in the process of solidifying around the metal pin of photomultiplier and produce bubble around the dividing potential drop board component; And then eliminate discharge, spark phenomenon, can prevent effectively that detection instrument is damaged.
Embodiment
Embodiment 1, and through test of many times, we successfully filter out a kind of solidification intensity height, the epoxide-resin glue of good insulation preformance.The name of glue is called JC-311 type adhesive.After using this adhesive, the low pressure discharge phenomenon does not take place in detector again under vacuum environment.Sum up the compound packaging technology of an effective photomultiplier of cover simultaneously.
1, with the clean photomultiplier of alcohol wash;
2, clean up the encapsulation usefulness the photomultiplier metal shell stand-by;
3, totally divide pressing plate and components and parts with alcohol wash, dry with hair-dryer;
4, will divide pressing plate and photomultiplier to weld;
5, stand-by by being in harmonious proportion JC-311 type adhesive at 1: 1 on clean metallic plate;
6, check the solder joint that divides between pressing plate and the photomultiplier pin;
7, on dividing potential drop board component surface and photomultiplier pin surface be coated with last layer JC-311 type glue equably, under room temperature 20 degrees celsius, solidified 24 hours;
8, check whether each components and parts and photomultiplier pin have the place of the gluing of not being coated with, and carry out secondary and mend glue;
9, mend behind the glue 20 degrees centigrade of cold curings 24 hours, the metal shell that photomultiplier is packed into and cleaned up;
10, by being in harmonious proportion electrically insulating silicone rubber at 1: 1, be injected into equably in the Can, under the condition of 18 degrees centigrade of room temperatures, solidified 24 hours.
Just finished the compound encapsulation of photomultiplier to this.
