Description
Technical field
The present invention relates to electronic product and clean field, particularly, relate to a kind of chemical composition and compound method thereof and its application in microwave module is produced.
Background technology
For cleaning the clean-out system of microwave module, mainly be used in cleaning after by reflow soldering of cavity and substrate in microwave module making processes and on substrate or cavity, carry out the cleaning after components and parts manual welding, object is to remove organism remaining in welding process and the dust granule of generation.
The trieline clean-out system in the past using, because environmental pollution is serious, now forbids.The clean-out system ethanol or the acetone that often use are at present inflammable organic solvent; a large amount of uses may cause fire and explosive hazard; and acetone also can be to people's the healthy very major injury that causes; and their cleansing power is all more weak; when cleaning, need long-time brew; even if also often can remain soldering flux after cleaning like this, affect thus quality product and reliability.
In addition, in prior art, also use nPB solvent, but n-Propyl Bromide in use airborne water vapor can enter, clean-out system is hydrolyzed, thereby acidifying corroding metal cavity occurs in hydrolytic process, make product rejection.Also easily there is cracking and go bad and scrap in nPB solvent chance illumination simultaneously.Thereby, clean microwave module with nPB solvent, there is qualified low, the shortcoming that cost is high of product.Therefore design a kind of environmentally friendly (environment-friendly type), safe, physico-chemical property stable and the strong new chemical cleansing composition of cleansing power is the problem that this area is needed solution badly.
Summary of the invention
The object of the invention is in order to overcome in prior art for cleaning the not environmental protection of clean-out system of microwave module, the defect that inflammable, physico-chemical property is unstable and cleansing power is poor, provide a kind of environmentally friendly, safe, physico-chemical property the stable and strong chemical composition of cleansing power, and the preparation method of this chemical composition and its application in microwave module is produced.
To achieve these goals, the invention provides a kind of chemical composition, wherein, monobromo substituent, Whitfield's ointment and bis sebacate that described chemical composition comprises n-propane.
The present invention also provides a kind of preparation method of chemical composition, and wherein said method is that monobromo substituent, Whitfield's ointment and the bis sebacate of n-propane are mixed.
The present invention also provides above-mentioned chemical cleaner and the application in microwave module was produced of the chemical cleaner prepared according to aforesaid method.
On the basis of the chemical cleaner (n-Propyl Bromide) that the present invention uses in the prior art, Whitfield's ointment and bis sebacate are added, thereby improve chemical cleaner physico-chemical property, make this chemical cleaner not there is combustibility, and this chemical cleaner also has excellent cleansing power and quick-drying characteristic, the life-span of this chemical cleaner in atmosphere is short simultaneously, thereby there is lower ODP and (refer to that certain material is within its atmospheric lifetime phase, the ratio of the ozone loss causing is discharged in the global ozone loss causing with respect to the CFC-11 of homogenous quantities), thereby make the environmental protection more of this chemical cleaner.This chemical cleaner cleans microwave module in microwave module is produced, and conforming product rate is reached more than 98%, thereby reduced production cost.
Other features and advantages of the present invention are described in detail the embodiment part subsequently.
