发明名称 Method for mounting semiconductor chip on circuit board
摘要 In mounting a semiconductor chip on a circuit board by a flip chip bonding method, an improved mounting method holds the circuit with a warp prevention device, on which the semiconductor chip is placed, while the circuit board is treated with heat for the reflow of the solder bumps. As a result, the circuit board is prevented from warping when heated at a temperature at which the solder bumps melt.
