Description

A kind of without cured polishing absorption layer and manufacture method thereof

Technical field

The invention belongs to grinding-material manufacturing technology field, particularly relate to a kind of without cured polishing absorption layer and manufacture method thereof.

Background technology

Traditional eyeglass, glass, wafer, sapphire, silicon chip glossing mainly adopt the cured polished bonding sheet method of painting. By needing the eyeglass ground, glass, wafer, sapphire, silicon chip to adopt cured liquid to be bonded on briquetting, the abrasive disk fit in milling apparatus carries out grinding and polishing. Its flatness being coated with cured technique and the quality of cured liquid, briquetting all can directly influence the quality of finish of the final lens product after polishing, glass, wafer, sapphire, silicon chip, causes its qualification rate low (bad, fragment, scratch, tolerance exceed standard).

Along with modern product to eyeglass, glass, wafer, sapphire, silicon chip required precision higher, the cured glossing of former painting can not meet the demand of product.

Through retrieval, Chinese patent literature publication number CN87202507U discloses a kind of silicon chip without cured polishing pad, though the patented product has its advantage, but its mosaic coating thickness is 300 ��m��400 ��m (0.3mm��0.4mm), can not meet the demand of current grind spectacle lens, glass, wafer, sapphire, silicon chip. The material expensive such as silicon chip, wafer, after thinning, brings a large amount of reductions of cost, along with the raising that properties of product are required by contemporary society, the progress of technology, use thickness more and more thinner, existing conventional silicon wafers, wafer thickness can be fabricated into 100 ��m, even thinner. A kind of silicon chip that this patent makes cannot meet grinding without cured polishing of the materials such as contemporary society's silicon chip, wafer without cured polishing pad. And this patent adopts the mosaic coating after processing and the direct bonding mode of remainder layer, the problems such as dislocation easily occur, (its adhesive layer one, the consistent size of mosaic coating need to be cut into and cut out the hole that mesophase spherule is same, in adhesion process, adhesive layer one easily misplaces in mosaic coating, form adhesive layer glue and be seeped into third layer adsorption layer surface blocking adsorption layer hole, cause product rejection problem. ) simultaneously adhesive layer one be very thin hot melt adhesive layer, machining center hole difficulty, the making qualification rate of product is relatively low, cost height.
