摘要： A solder-ball-supplying method, a solder-ball-supplying device and a solder-bump-forming method, which are flux-less and capable of being also applied to electrodes having a fine pitch. A substrate on which a resist with openings is positioned on electrode(s), which has a diameter of 10 through 30 μm, of the substrate is prepared. Next, plural solder balls SBL each having a grain diameter of 1 through 10 μm are shaken down to the opening(s) of the resist from a hopper and filled therein. Next, by sliding and moving a squeegee on an upper surface of the resist along X-Y direction, the solder balls SBL shaken down to the resist other than the openings are scrapped and removed and the solder balls SBL in the openings and around them are pushed into the openings by the squeegee.

摘要： The present solder transfer sheet addresses the issue of providing a solder transfer sheet having both solder powder holding properties and sheet releasing properties and having excellent solder transfer properties. This solder transfer sheet is for soldering in a section to be soldered in a circuit substrate and has: a support base material; an adhesive layer provided on at least one surface of the support base material; and at least one solder layer including solder particles, provided upon the adhesive layer. The adhesive layer contains a side-chain crystalline polymer, exhibits viscosity by having fluidity at at least the melting point of the side-chain crystalline polymer, and decreases viscosity by crystalizing at temperatures less than the melting point of the side-chain crystalline polymer.

摘要： Provided is a solder transfer sheet which is capable of increasing the amount of solder to be transferred without the occurrence of bridging. A solder transfer sheet 1A includes a base material 5, an adhesive layer 4 formed on the surface of the base material 5, a solder powder-containing adhesive layer 3 formed on the surface of the adhesive layer 4, and a solder powder layer 2 formed on the surface of the solder powder-containing adhesive layer 3. In the solder powder layer 2, particles of solder powder 20 are arranged in a one-layer sheet form. In the solder powder-containing adhesive layer 3, solder powder 30 and an adhesive component 31 are mixed so as to have such a thickness that two or more layers of the solder powder 30 are stacked.

摘要： In the flux applying device, a control portion controls conveying rollers or the like so that thickness of flux applied to solder is controlled. The winding roller rotates so that the solder is conveyed at the conveying speed. The drawing-out roller applies any load (back tension) to the solder backward along the conveying direction of the solder when drawing out the solder. The solder is conveyed at the predetermined speed and dipped into the flux tank containing flux. The solder is pulled up from the flux tank at the conveying speed vertically. By pulling up the solder from the flux tank at the constant conveying speed vertically, the interfacial tension acts on the solder 9a and the flux, so that the flux having a uniform thickness according to the conveying speed remains on the surface and back surface of the solder.
