Abstract
The utility model relates to a packaging structure of metallographic specimens of printing boards. The packaging structure comprises a packaging mold and attached connecting plate specimens which are embedded in the packaging mold. The packaging structure is characterized in that the multiple attached connecting plate specimens are arranged in a mutually parallel manner and are fixed in the packaging mold through positioning devices. For the packaging structure, the multiple specimens can be packaged in the packaging mold, the manufacturing cost of the metallographic specimens is substantially saved under the condition that the metallographic analysis and examination is not affected, the number of packaging specimens is reduced, the manufacturing time of the specimens is shortened, and the working efficiency is improved.
Description
Technical field
The utility model relates to printed board metallographic detection range, relates in particular to a kind of printed board metallographic specimen encapsulating structure.
Background technology
Along with the growth of my institute's research and production task, the usage quantity of printed board is also in sharp increase, and the printed board inspection task that we faced not only increases substantially in quantity.The quality standard aspect is also constantly improved and the raising standard, and in order to increase work efficiency, we are in the packaging technology improvement that guarantees to have done under the impregnable prerequisite of work quality metallographic specimen.Referring to Fig. 1, originally the attached plates sample uses 10 clampings of sample clip, in the middle of sample, has very big space all to fill with potting resin like this, cause space waste also to expend lot of materials (potting resin), and sample clip 10 costs is high.
The utility model content
In order to solve existing technical matters in the background technology; The utility model provides printed board metallographic specimen encapsulating structure; Can in an encapsulating mould, encapsulate a plurality of samples, guaranty money's facies analysis is checked under the impregnable prerequisite, practices thrift the metallographic specimen cost of manufacture in a large number.
The technical solution of the utility model is: printed board metallographic specimen encapsulating structure; Comprise encapsulating mould and embed the attached plates sample in the encapsulating mould; Its special character is: said attached plates sample is a plurality of; Laterally arrange each other, said a plurality of attached plates samples are fixed by positioning device in encapsulating mould.
Above-mentioned locating device is a tommy, and said tommy runs through a plurality of attached plates samples.
Above-mentioned tommy is two.
It is the encapsulating material of one that the inner filling of above-mentioned encapsulating mould makes attached plates sample and tommy and encapsulating mould.
Be provided with and the suitable pilot hole of tommy on the above-mentioned encapsulating mould.
Above-mentioned encapsulating material is an epoxy resin.
The printed board metallographic specimen encapsulating structure of the utility model can encapsulate a plurality of samples in an encapsulating mould, guaranty money's facies analysis is checked under the impregnable prerequisite; A large amount of metallographic specimen costs of manufacture of practicing thrift; Reduce the encapsulation sample quantities, shorten the sample production time, increase work efficiency.
Processing cost before transform per 10000 at the required sample holder 20000 of making sheet, potting resin 60000ml makes 120000min in man-hour; Making needs 5720 of 0.9mm*35mm draw points after 6667 on sample is changed into transformation; Potting resin 42900ml, man-hour, 80000mi made 2858 on sample.Material cost is practiced thrift: (20000*7+60000/4750*2000)-(42900/4750*2000) about 14.5 ten thousand, practice thrift man-hour: 3666 hours.Metallographic specimen quantity is significantly reduced, and more helps storing.
Description of drawings
Fig. 1 is the prior art structural representation of the utility model;
Fig. 2 is the structural representation of the utility model;
Embodiment
Referring to Fig. 2, the printed board metallographic specimen encapsulating structure that the utility model proposes comprises encapsulating mould 1 and embeds the attached plates sample 2 in the encapsulating mould; Attached plates sample 2 is a plurality of, laterally arranges each other, and a plurality of attached plates samples 2 are fixed in the encapsulating mould 1 through tommy 3; Tommy 3 runs through a plurality of attached plates samples 2; Tommy 3 mainly is the mode that adopts draw point, draw point specification 0.9mm*35mm, the bottom surface level of encapsulating mould 1; The attached plates sample 2 that tommy 3 fixes directly is placed in the encapsulating mould 1; The pilot hole suitable with tommy 3 arranged on the encapsulating mould 1, tommy 3 through pilot hole with its stationkeeping, thereby the position of the attached plates sample 2 that tommy is ined succession is also just fixing.Tommy 3 is two; Particular location can be adjusted when encapsulating according to the size of attached plates sample 2; Purpose is to be to make the position of attached plates sample 2 can not be moved; It is the encapsulating material of one that encapsulating mould 1 inner filling makes attached plates sample and tommy and encapsulating mould, and encapsulating material is an epoxy resin.
Claims (6)
1. printed board metallographic specimen encapsulating structure; Comprise encapsulating mould and embed the attached plates sample in the encapsulating mould; It is characterized in that: said attached plates sample is a plurality of, laterally arranges each other, and said a plurality of attached plates samples are fixed by positioning device in encapsulating mould.
2. printed board metallographic specimen encapsulating structure according to claim 1, it is characterized in that: said locating device is a tommy, said tommy runs through a plurality of attached plates samples.
