PRINTED-CIRCUIT BOARD WITH EMBEDDED PATTERN, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a printed-circuit board and a structure embedded in the inside of a circuit insulating layer to prevent undercut and provide a fine circuit.

SOLUTION: The printed-circuit board includes a first insulating layer 300, a second insulating layer 500 formed on the first insulating layer 300 and having an opening part for forming a circuit layer, and a circuit layer 900 comprising a conductive metal filled in the opening part. A composition surface is formed between the first insulating layer 300 and the second insulating layer 500.
