Abstract
The adhesive for superprecision processing of superthin chips consists of shellac 34-40 wt%, rosin 58-64 wt% and turpentine 2-3 wt%, which are heated and mixed at 100-140 deg.c. During its preparation, rosin is first heated to its smelting point 100-140 deg.c, and shellac and turpentine are added successively via stirring. It has high adhesion, relatively high hardness and less deformation. During its preparation, rosin in greater amount is used in summer for harder adhesive and rosin in smaller amount in winter.
Description
Technical field: the viscose glue of ultra thin single crystalline single substrate mass ultraprecise processing is meant to the single-sided polishing monocrystal chip is provided, satisfy corresponding quality standard, adapt to the mass production requirement, two geometrical shapies are identical, and the close monocrystal chip of surface quality is with special processing method of carrying out cold worked glue of crystal and configuration processing glue glued together.
Background technology: the bonding of substrate must have intermediate medium, and very strict for the requirement of intermediate medium.Cause has certain pressure and frictional force in its course of processing, thus require intermediate medium that certain rigidity and viscosity must be arranged, and also clean, under suitable high temperature weight, insoluble indeformable.Make us on selecting and researching and developing, very big difficulty arranged based on particular requirement to middle medium.Through many times experiment we from coating agent which has to be dissolved in alcohol before use, be in harmonious proportion to select a series of intermediate mediums such as glue, cloth insertion sheet, glue and be in harmonious proportion glue and do binding.The glue that is in harmonious proportion has plenty of and mixes at a certain temperature by a certain percentage.General weight percent is rosin 10-40%, beeswax 60-90%.Rosin is put into the pot of heating, and big fire makes its fusing, the adding beeswax that stirs, and because of the beeswax fusing point is lower, proportion is lighter, can occur beeswax, a small amount of demixing phenomenon of rosiny so mix after static.Can find that after solidifying the superiors are shallow, this is the immiscible beeswax of part, and foot is dark, is light/dark balance and harder, and Here it is not have the rosin that mixes with beeswax.Because upper and lower two-layer not dissolving, cause out of proportion, so available has only the intermediary sub-fraction.And the very difficult grasp of this sub-fraction in different seasons, constantly change by producing seasonal temperature, it is this that difficult to grasp property more and more obvious.Its shortcoming is: stability is bad.Simultaneously, in summer, the temperature height should use harder mediation glue, and winter is then just opposite.Existing mediation glue is not easy to adjust soft or hard.
Summary of the invention: it is bad that purpose of the present invention will solve existing mediation glue stability exactly, prescription of the same race is difficult for along with the different problems of adjusting soft durometer in season, provide a kind of mixing quality stable, can adjust soft durometer, be used for the bonding mediation glue of ultra thin single crystalline single substrate mass ultraprecise processing.
Mediation glue of the present invention is to be mixed by weight percent shellac 34-40%, rosin 58-64%, turps 2-3%.Terebinthine ratio range is preferably near 2%, i.e. 2-2.2%.Technology of the present invention is to mix in a certain temperature 100-140 ℃ heating in such ratio.Earlier rosin (because of its fusing point height, impurity different melting points difference is generally at 100-140 ℃) being heated to 100-140 ℃ of its fusing point, add shellac (coating agent which has to be dissolved in alcohol before use) and stir, make its even fusing, add turps again, also is that the limit bevelling stirs.Advantage: viscosity is preferably arranged, better hardness, indeformable under proper temperature and pressure, bonding smooth, even.In summer, the temperature height should use harder mediation glue, and the rosiny ratio is big slightly, and winter is then just opposite.Ebonite disposes preferably weight percent shellac 34-36%, rosin 62-64%, and terebinthine ratio range is preferably near 2-2.2%.Flexible glue disposes preferably weight percent shellac 38-40%, rosin 58-60%, and terebinthine ratio range is preferably near 2-2.2%.Shellac and rosin are put into the pot of heating, and big fire makes its fusing, the adding turps that stirs, the mediation configuration processing method basically identical of soft or hard viscose glue.
Viscose glue of the present invention and configuration technology are compared with existing technology, possess following characteristics:
1, suitable hardness:
Because there is certain longitudinal pressure in its course of processing, and pressure took place in the different process stage, and difference changes, the hardness of adaptation different pressures variation is very crucial.
2, suitable intensity:
In the course of processing, substrate is owing to be subjected to the influence of horizontal differentiated friction power, and viscose glue must possess corresponding strength, to adapt to the influence of different directions pulling force.
3, adapting to differing temps changes:
Comprise two aspects, will adapt to mechanical self-temperature condition variation in the course of processing on the one hand; To adapt to processing site indoor environment temperature variation and outdoor seasonal variation on the other hand and cause temperature variation.
4, processable:
For adapting to the mass production requirement, viscose glue must dissolve in special solvent fast, so that clean, pack, enhances productivity.
5, simple for process, the viscose quality after the processing is stable, is convenient to long-term storage and uses.
