摘要： Disclosed are a method for preparing a high performance BGA board and a jig applicable to the method. The method comprises pre-bonding an adhesive to a BGA board laminated structure or a heatsink by use of a jig; and main-bonding the BGA board laminated structure or the heatsink to which the adhesive is previously stuck in the pre-bonding step to the heatsink or the BGA board laminated structure, respectively, by use of a jig. A high performance BGA board can be prepared by use of an individual heatsink and a strip-type jig without a strip-type heatsink, and in which the Ni-plated side of the heatsink can be prevented from being contaminated.

摘要： Disclosed are a method for preparing a high performance BGA board containing a plurality of printed circuit boards in which a conductor circuit, a bonding pad electrically connected to a semiconductor chip, and an inner hole for mounting a semiconductor chip are formed, by primary- and secondary-laminating a plurality of boards. The present invention enjoys advantages in that contamination due to an outer layer surface treatment of the board laminate can be prevented, and a process for preventing a contamination of an inner hole can be omitted, and also a defective proportion can be reduced remarkably in comparison with prior arts by applying a pressure uniformly during a secondary lamination. Furthermore, a BGA board according to the invention has an ideal ball pitch and multi-fins, excellent electrical and thermal properties, also can be applied in the case of high current, and can be easily mounted on a chip.

摘要： A method for manufacturing a printed circuit board is disclosed. When a metal is plated on an upper board to form a circuit, bonding fingers for being bonded with a semiconductor chip are prevented from being electroplated with a metal. That is, a slot with an ink layer formed therein is formed in each of a plurality of boards. Then window regions of different sizes are defined, and a working is carried out on the portion where the slots are not formed. That is, the copper clad laminates are subjected to a working to form slots, and an ink layer is formed within each of the slots. In this manner, during the plating of the upper face of the printed circuit board, the metal is prevented from intruding into the window region, thereby preventing the formation of a short circuit.
