Method for producing tiny soldered balls with repeatedly-usable substrates

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.

Angle cutter realizing smooth cutting and preventing burrs of end side and implementation method of angle cutter

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.

Rapid high-precision distribution device with breaking device

The invention discloses a rapid high-precision distribution device. The rapid high-precision distribution device comprises a belt-type conveying device, a material cabin, a material blocking device, aweighing hopper, and a control system. The material cabin is cooperatively installed above a conveying belt, and the bottom thereof is slightly higher than the conveying belt. The material cabin is used for storing a material, and comprises a material cabin body and a cabin door. The material blocking device is cooperatively and fixedly installed with the conveying belt, positioned above the conveying belt, and perpendicular to the conveying belt. The material cabin is positioned behind a moving direction of the conveying belt. The weighing hopper is cooperatively installed below the tail endof the conveying belt. The control system is used for receiving data of the weighing hopper, calculating, and controlling the work of the belt-type conveying device, the cabin door and the material blocking device. The device is capable of realizing rapid-speed feeding, intermediate-speed feeding, slow-speed feeding, and accurate feeding; high in feeding precision, rapid in speed, and suitable for solid particles, powder, and an adhesion mixture; and small in repetitive control precision deviation without a loose material.

Intermittent automatic feeding material bin with material fluffing prevention function

The invention discloses an intermittent automatic feeding material bin with a material fluffing prevention function. The intermittent automatic feeding material bin comprises a material bin body, a material bin cover, a feeding port and a discharging port, an air blowing pipeline is arranged in the material bin body, the air blowing pipeline is installed on the material bin cover in a suspended manner, a front end port of the air blowing pipeline is connected with an external air source through an air inlet pipeline, an electromagnetic valve is installed on the air inlet pipeline, a lower end port of the air blowing pipeline is closed, meanwhile, air outlet holes are distributed in the air blowing pipeline, and a breathing port used for exhausting air is further formed in the material bin cover. According to the intermittent automatic feeding material bin, compressed air is introduced from the upper portion of the air blowing pipeline, compressed and caked powder at the bottom of the feeding material bin is blown away under the action of wind force generated when the compressed air is blown out through the air outlet holes, the situation that the compressed and caked powder is fluffy at the bottom of the material bin is prevented, the aims of feeding materials in time and reducing material compaction and caking are achieved, the risk of material breakage is reduced, and the production efficiency is improved.

Full-coating sweeping anti-lock abrasion resisting ball valve

The invention discloses a full-coating sweeping anti-lock abrasion resisting ball valve, and relates to the technical field of ball valve cleaning. The full-coating sweeping anti-lock abrasion resisting ball valve comprises a ball valve component, an executer, a receiving disc and two adapter flanges. A switch ball is arranged in a containing cavity and connected with a valve rod. The valve rod stretches out of the containing cavity and is connected with the executer. The executer is connected with the receiving disc. The receiving disc is arranged on a valve body and connected with the valve body through a mortise assembly. Two sweeping holes communicate with the containing cavity. Compared with ball valves in the prior art, according to the provided full-coating sweeping anti-lock abrasion resisting ball valve, due to the adoption of the mortise assembly connected between the receiving disc and the valve body and the valve body communicating with the adapter flanges through the sweeping holes, the situation that in the frequent valve rod opening and closing process, components are shaken loosely can be avoided; and deposited materials in the containing cavity can be cleaned, the switch ball is prevented from being locked, practicability is high, and cost performance is high.
