Description
Technical field
The present invention relates to a kind of environment-friendly type weakly alkaline low temperature deburring bating liquor, particularly a kind of preparation and method of use thereof of environment-friendly type weakly alkaline low temperature softening liquid of epoxy-plastic packaging chaeta thorn.
Background technology
Electronic product components and parts such as semiconductor packages, pcb board printing, passive components and parts are before zinc-plated; Because micromolecular epoxy resin good fluidity in the chip plastic packaging process; What meeting was unnecessary becomes one deck resin film at substrate surface and pin place row, is commonly called as to be burr or flash.If this flash is not handled, can cause the electrolytic coating bad order, leak copper, so that influence the weldability of product, finally have a strong impact on the safety of electronic devices and components.Therefore deburring technology is the important component part in the electronic component products electroplating process.
Passive components and parts comprise resistance, electric capacity, inductance, coil and magnetics etc., and the output value has in recent years reached 22,000,000,000 dollars.The high growth of passive components and parts has further promoted the galvanized demand of electronic devices and components, and therefore being badly in need of will supporting with it pretreatment procedure.Principle in line with energy-saving high-efficiency environment-friendly this shows, the market demand of environment-friendly type weakly alkaline low temperature deburring bating liquor is huge.
At present outstanding environment-friendly type weakly alkaline low temperature deburring bating liquor also is to count seldom, is detected in a small amount of data report of states such as America and Europe, and also not large-scale production and market-oriented.Domestic traditional method generally is to adopt mineral acid or organic solvent high temperature to soak, and main problem one is that service temperature is high, and energy expenditure is big; Mineral acid reactive behavior increase at high temperature in addition; Can corrode metal substrate and plastic-sealed body surface, and organic solvent one is to cause the plastic-sealed body variable color easily at high temperature, causes problems such as burning in addition easily; The SF of operating environment is little; And general organic solvent is all volatilizations easily at high temperature, produce a large amount of smells, have also caused the waste of the material and the energy.There is part enterprise to adopt the technology of electrochemical deburring in addition; Because need expensive electrochemical deburring equipment; Invisiblely for middle-size and small-size producer increased huge economic pressures, what electrochemical deburring adopted in addition is the highly basic electrolysis, also easily metal substrate is caused corrosion.
Summary of the invention
In order to overcome the deficiency that exists in the prior art, the present invention provides a kind of environment-friendly type weakly alkaline low temperature deburring bating liquor, and is satisfactory for result; The deburring temperature is low; No toxic and harmful produces, whole process safety and environmental protection, and because adopted the composite of AS and nonionogenic tenside; After removing flash, the greasy dirt of substrate surface and other pollutents are also removed clean in the lump.
Technical scheme: for solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of environment-friendly type weakly alkaline low temperature deburring bating liquor; Its each component and weight percent are: THF 10-35%, Ucar 35 10-35%, TX10 1-5%; Thanomin 5-20%, N methyldiethanol amine 1-10%, all the other are water.
The present invention also provides the preparation method of said environment-friendly type weakly alkaline low temperature deburring bating liquor, it is characterized in that may further comprise the steps:
The water that in container, adds 2/3 amount under the condition of stirring, adds THF by proportioning; Stir, at the uniform velocity add Ucar 35, continue to stir 5-10 minute by proportioning; At the uniform velocity add TX10 by proportioning; Continue to stir 5-10 minute, at the uniform velocity add thanomin, stirred 5-10 minute by proportioning; Stir down and continue to add N methyldiethanol amine, moisturizing to aequum stirred 1 hour, packed for standby use.
The present invention also provides the method for use of said environment-friendly type weakly alkaline low temperature deburring bating liquor; Earlier said environment-friendly type weakly alkaline low temperature deburring bating liquor is added in the stainless steel tank; Be warming up to 50-80 ℃; Pending components and parts input was soaked 20-60 minute, take out then and gently scrub clean or high pressure water jets drip washing gets final product only with brush.
Beneficial effect: environment-friendly type weakly alkaline low temperature deburring bating liquor of the present invention adopts THF and Ucar 35 to make solvent; And add distinctive tensio-active agent mixed system; Only need pending components and parts be put into softening tank during zinc-plated pre-treatment deburring; 50-80 ℃ digestion 20-60 minute; Can make components and parts surfaces burr softening, follow-uply rinse well or high pressure water jets drip washing can get into subsequent handling only, soak the back product through this environment-friendly type weakly alkaline low temperature deburring bating liquor and need not to get into the oil removing operation through the light brush of brush.It is low that the present invention has the bating liquor service temperature, and the burr bating effect is good and can remove the characteristics of substrate surface greasy dirt, the generation of no toxic and harmful; Materials safety that is adopted and environmental protection, the complete compliance with environmental protection requirements of formula material, product are stable, waste liquid adds about acid adjustment pH value 7-8 in the use, can enter waste liquid pool.Use temperature is low, and technology is very simple, and the follow-up maintenance cost is very low, is particularly suitable for energy-efficient requirement.
