Description
Technical field
The present invention relates to the thick film circuit technique field, particularly relate to a kind of thick film circuit surface protection glass glaze slurry and preparation technology thereof.
Background technology
The utilisation technology that the low temperature flux is made the field at thick film integrated circuit is very ripe, be mainly used in the glass binder of the printing slurry of the thick film elements such as conduction band, resistance, electric capacity, inductance as thick film circuit, also be used for the piece of surface covering glass glaze of thick film conduction band and thick film element.
In the conventional art, glass glaze prescription as surface coverage is normally such: prepare first a class and have the flux of good characteristic as basic recipe, add metal, the nonmetallic compound that a class is adjusted performance (such as the new softening temperature of determining, linear expansivity, relevant mechanical properties, tear crystalline substance, goods color etc. open) according to the requirement of specific product again, the viscosity that requires according to the glaze slurry at last adds tackiness agent, through mixing the glaze printing slurry that becomes certain fineness with ball milling.
But, traditional flux powder (base side), mostly contain a certain amount of lead, the Pb-Si-O network is that this class flux has the key of stability, other flux is all introduced a large amount of low melting point prices higher expensive metal or nonmetallic compound basically except more or less leaded.
On January 27th, 2012, European Parliament and the instruction 2002/95/EC of senate " be limited in electric and electronics in use certain objectionable impurities " (ROHS), require to guarantee that the product that on July 1st, 2006 rose to put goods on the market does not contain certain objectionable impurities.Lead is one of heavy noxious metals material of belonging to of ROHS appointment, and plumbous limiting the quantity of in correlated product only is 1000ppm, and since then, product unleaded become a for many years big hot topic problem of novel material and index of correlation technical study.In addition, plumbous heavy corrosion has high corrosion failure to glass smelting equipment and utensil.This has increased the cost of product from another point of view.
In addition, thick film conduction band, element, the common prescription of glass-glazed printing slurry are formed by the abundant hybrid modulation of tackiness agent that solid powder and organic, water-fast oil, ester, Mierocrystalline cellulose form, this class slurry when construction, contains strong impulse toxicity smell and gas usually.Construction process is seriously polluted to equipment, clamping apparatus, human body and dress ornament, and it is large to cause cleaning intensity, and maintenance cost is high, and this class printing ink is once construction, and the printing ink that expends beyond the construction workpiece is owing to the chemical reason is difficult to reclaim.
Therefore, not enough for prior art, provide a kind of thick film circuit surface protection functional, low-cost, environmental protection very necessary with glass glaze slurry and preparation technology thereof.
