摘要: A method of forming an assembly of a substrate and a flip-chip having solder balls thereon, the method having steps of: placing the flip chip with the solder balls in contact with the substrate to form a first interim assembly at a first predetermined temperature; providing an encapsulant to the first interim assembly to form a second interim assembly at a second predetermined temperature that is lower than a melting temperature of the solder balls and higher than the first predetermined temperature; and subjecting the second interim assembly to an environment of a third predetermined temperature that is sufficient to melt the solder balls. An encapsulant for use in forming an assembly of a substrate and a flip-chip having solder balls thereon, the encapsulant consisting essentially of: an epoxy resin; an anhydride curing agent; a fluxing agent having a hydroxyl (-OH) group; and an inorganic filler.
