Fabrication of thin sheets of glass or other substrate material for use in devices such as touch sensor panels is disclosed. A pair of thick glass sheets, typically with thicknesses of 0.5 mm or greater each, may each be patterned with thin film on a surface, sealed together to form a sandwich with the patterned surfaces facing each other and spaced apart by removable spacers, either or both thinned on their outside surfaces to thicknesses of less than 0.5 mm each, and separated into two thin glass sheets. A single thick glass sheet, typically with a thickness of 0.5 mm or greater, may be patterned, covered with a protective layer over the pattern, thinned on its outside surface to a thickness of less than 0.5 mm, and the protective layer removed. This thinness of less than 0.5 mm may be accomplished using standard LCD equipment, despite the equipment having a sheet minimum thickness requirement of 0.5 mm.

The present invention involves building sheets with a plurality of grooves indented into a surface of the building sheet to provide a guide for cutting the building sheet along the grooves. Preferably, the grooves are arranged in a regularly repeating pattern and are spaced apart by a standard unit of measurement in order for a cutter to accurately size the building sheet to a precise dimension. A simple scoring knife is preferably used to score the sheet along the grooves, without the need for a straight edge, and the sheet is broken by simply bending the sheet of along the score mark. The grooves are preferably provided at a depth into the surface the sheet such that they do not substantially decrease the strength of the sheet or affect off-groove scoring. Thus, a score mark can be made between or across grooves without deflection of the mark into a groove and without breakage of the sheet along a groove when the sheet is bent.

The invention provides a preparation method of plywood of E0 grade. The urea formaldehyde resin adhesive has an advantage of simple preparation technology, good reproducibility, lower cost and long store time. By using the urea formaldehyde resin adhesive, the plywood/three-ply board/overlaying panel/multilayer board accord with the requirements of plywood of E0 in terms of the bonding strength and the formaldehyde emission. The method in the invention has the advantages that: the preparation of the urea formaldehyde resin adopts the alkali-acid-alkali traditional craft; the urea and the melamine are added in three times; the urea is added in three times which adjusts the quality of the resin molecule; especially, the urea, which is added in the second time, not only degrades and resets the large molecules but also decreases the content of the ether linkage and reduces the release of the formaldehyde; during the composite process, the pH value in the condensation polymerization is rigidly controlled; by the two-step condensation polymerization, the condensation polymerization can rapidly proceed in good order.
