The invention relates to a method for manufacturing a small solder ball, in which a substrate is reusable. The invention is characterized in: firstly, the reusable substrate is prepared by means of IC manufacture process: a silicon wafer is used as a base, a metal conducting layer is sputtered from the front after heat oxidation treatment; secondly, the small solder ball is manufactured on the reusable substrate: a metal sacrificial layer is sputtered on the substrate to cover the opening of the conducting layer, thick photosensitive resist is coated and an electroplating window is photoetched, then solder is electroplated, the thick photosensitive resist is removed after electroplating, the solder is reflowed to form a solder ball, thereafter the metal sacrificial layer is corroded to be removed, so that the solder ball can drop off completely from the reusable substrate, and finally the solder ball is collected. According to the invention, the manufacturing procedure is simple and consumes small energy, the process has good controllability, the bottleneck of low productivity is overcome; the manufactured solder ball has smooth surface, good sphericity and uniform size, with the smallest grain diameter being 0.15mm.

The invention relates to a making method of an anti-static lamination type support pad for protecting an LCD panel. According to the making method, a polyolefin film of an anti-static layer is at least formed on one surface or two surfaces of a polyolefin or polyurethane foam sheet by virtue of lamination. The lamination type support pad made by using the making method can be used as a panel lamination type support pad which is used for preventing the surface from being scraped, polluted and impacted and is especially sensitive to static electricity when a liquid crystal display panel is stored and conveyed, and can be used for effectively preventing the edge of the lamination type support pad from fluffing, further effectively reducing the dust generation rate and preventing foreign matters from permeating between the lamination type support pads.

The invention discloses an angle cutter realizing smooth cutting and preventing burrs of an end side and an implementation method of the angle cutter. The angle cutter comprises a bedplate; the bedplate is provided with a cutting slot; the cutting slot is used for a cutting knife wheel to pass through and is arranged along a rectilinear direction; inside the cutting slot, one end provided with no cutting knife wheel is filled with a fragile insert; and an exposed end face of the fragile insert is smooth and is flush with the upper end face of the bedplate. The main concept of the angle cutters still starts with elimination of a clearance between the cutting knife wheel and the cutting slot to make sure that a sawed material is always supported and burrs caused by inertial rupture in a cutting process can be prevented, so the first problem to be solved is installation precision; however, the angle cutter disclosed by the invention steers clear of the installation precision problem, the cutting slot and the cutting knife wheel still have the clearance, but the cutting slot is filled with the fragile insert, and the final actual movement direction of the cutting knife wheel is generated by cutting when being started for the first time, so the cutting knife wheel has no clearance with the clearance at the fragile insert.
