Beschreibung
Zusammenfassung:	Disclosed herein are prepreg, a copper clad laminate (CCL), and a printed circuit board. When a reinforcing member formed of organic fiber including a liquid crystal polymer resin or a super engineering resin and a base resin having the same component as the reinforcing member are used, a coefficient of thermal expansion (CTE) and rigidity may be adjusted. In addition, during an operation of a semiconductor chip mounted on the printed circuit board, the semiconductor chip and the printed circuit board expand and contract due to heat by as much as similar degrees, and thus, the reliability of a solder joint may be enhanced. Moreover, fiber protrusion failure may be prevented compared with a case a via hole is processed by using a CO2 laser drill, thereby minimizing substrate failures.
