PRINTED CIRCUIT BOARD AND MANUFACTURE METHOD THEREOF

摘要

Disclosed are a printed circuit board capable of improving heat dissipation and strength against warping through the use of aluminum, and a method of manufacturing same. The printed circuit board may be configured to include: a core portion formed of an aluminum material; a base layer formed of an aluminum material and bonded on both side surfaces of the core portion; a bonding member interposed between the core portion and the base layer in order to bond the base layer to the core portion; a via hole formed through the core portion, the bonding member, and the base layer; a substitution layer formed to ionize a portion exposed to the surface of the base layer and the inside of the via hole; and a plate layer formed on the substitution layer and having a circuit pattern formed thereon.
