Multilayer printed circuit board and method of manufacturing multilayer printed circuit board

摘要

A multilayer printed circuit board which can surely establish interlayer connection with low resistance. The multilayer printed circuit board comprises: a first substrate having a conductive pattern on one face and a non-penetration connection hole on the other face, for exposing the conductive pattern to outside; a second substrate having a conductive pattern formed on a face opposed to the other face of first substrate and a conductive bump on the conductive pattern integrally. The first substrate and the second substrate are integrated by engaging the bump of the second substrate with the connection hole of the first substrate and by intervening a conductive cement between the bumps and the conductive pattern exposed to outside from the connection holes.
