ABSTRACT:
An apparatus for producing a multi-layer printed circuit board. The printed circuit board includes a bottom layer board, a hole board, and an adhesive sheet between the bottom layer board and the hole board. The printed circuit board is heated so that adhesive sheet bonds the bottom layer board to the hole board. A mold release sheet and a thermoplastic resin sheet begins to soften at a temperature lower than the melting temperature of the adhesive. A contraction control member controls contraction when the thermoplastic resin sheet cools.
