SUBSTRATE FOR PRINTED CIRCUIT BOARD AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide base materials for a printed circuit board whose position deviation can be prevented at the time of carrying out the melting lamination and integration of circuit layers. SOLUTION: Base materials for a printed circuit board using sheet base materials constituted of at least two kinds of thermoplastic liquid crystal polymers has characteristically the softening points of the polymers different from each other.
