摘要： Hybrid molds for molding a multiplicity of solder balls for use in a molten solder screening process and methods for preparing such molds are disclosed. A method for forming the multiplicity of cavities in a pyramidal shape by anisotropically etching a crystalline silicon substrate along a specific crystallographic plane is utilized to form a crystalline silicon face plate used in the present invention hybrid mold. In a preferred embodiment, a silicon face plate is bonded to a borosilicate glass backing plate by adhesive means in a method that ensures coplanarity is achieved between the top surfaces of the silicon face plate and the glass backing plate. In an alternate embodiment, an additional glass frame is used for bonding a silicon face plate to a glass backing plate, again with ensured coplanarity between the top surfaces of the silicon face plate and the glass frame. In a second alternate embodiment, a silicon face plate is encased in an extender material which may be borosilicate glass or a polymer. The encasing is performed on a leveling fixture such that the top surface of the silicon face plate and the top surface of the extender material after solidification are perfectly leveled.

摘要： The present invention discloses a method and apparatus for forming solder bumps by a molten solder screening technique in which a flexible die head constructed of a metal sheet is utilized for maintaining an intimate contact between the die head and a solder receiving mold surface. The flexible die head, when used in combination with a pressure means, is capable of conforming to any curved mold surface as long as the curvature is not more than 2.5 .mu.m per inch of die length. The present invention further provides a method and apparatus for filling a multiplicity of cavities in a mold surface by providing a stream of molten solder and then intimately contacting the surface of the molten solder with a multiplicity of cavities such that the molten solder readily fills the cavities. The apparatus further provides means for removing excess molten solder from the surface of the mold without disturbing the molten solder already filled in the cavities. The present invention further discloses a flexible die for dispensing molten solder consisting of a die body that is constructed of a metal sheet capable of flexing of not less than 1.5 .mu.m per inch of die length, a gate opening for receiving a supply of molten solder, a slot opening for dispensing the molten solder onto a solder receiving surface, and a pressure means associated with the die body for providing adequate pressure such that the die body intimately contacting the solder receiving mold surface.

摘要： An apparatus and a method for transferring solder bumps from a solder mold to a solder-receiving substrate are disclosed. The apparatus includes a transfer fixture constructed by a base member, a lid member and a compressible member for holding a mold/substrate assembly therein. A plurality of compression pins are mounted through the lid member for supplying a uniform pressure on the mold/substrate assembly and for allowing lateral motion of the mold/substrate assembly relative to the transfer fixture due to a mismatch in the coefficients of thermal expansion. The compressible member is a cellulosic foam sheet which applies a uniform joining force across the entire surface of a wafer and assures abutting contact between the entire wafer and the mold surface. The foam sheet further assists in the lateral movement of the mold/substrate assembly relative to the base member of the transfer fixture.

摘要： There is provided a method for applying solder to an element on a surface of a substrate. The method comprises the steps of (a) placing a mold over the surface, where the mold includes a conduit that contains the solder, and (b) heating the solder to a molten state so that the solder flows from the conduit onto the element. The conduit enjoys two degrees of horizontal freedom with respect to the surface such that the conduit becomes substantially aligned with the element when the solder is in the molten state. There is also provided a system for applying solder to an element on a surface of a substrate.
