Abstract: PURPOSE: A method for manufacturing a ball grid array package is provided to prevent neighboring fluxes from being shorted even if a pitch between solder ball pads becomes finer, by temporarily applying heat to melt the fluxes when a solder ball is settled in the solder ball pads after flux of a predetermined thickness is applied on the surface of the solder ball. CONSTITUTION: A semiconductor chip having bonding pads is adhered to a surface of a board having conductive patterns and solder ball patterns by intervening an adhesive. An end of the conductive patterns is bonded to the bonding pads to electrically connect the semiconductor chip with the board. The side surface of the semiconductor chip and the surface of the board are molded by using an epoxy molding compound. After the solder ball pads exposed to the other side of the board and solder balls(150) absorbed to a solder ball fix jig are aligned, the solder balls are settled on the solder ball pads. The solder ball coated with flux is heated to completely connect the solder ball pads with the solder ball by a backward process.
