Zusammenfassung: | PURPOSE: A printed circuit board having a resistor embedded in a board capable of directly embedding a resistor in a conductive pattern of a printed circuit board by directly forming a conductive pattern between contact points of a printed circuit board as a resistor pattern of a corresponding resistance and a manufacturing method thereof are provided. CONSTITUTION: In a manufacturing method of a printed circuit board, a resistor metal(2) is thermo-compressed on a board(1). A conductive metal(3) and a photoresist are sequentially formed on the thermo-compressed resistor metal(2). The photoresist is patterned according to a circuit pattern to be formed. The conductive metal(3) is etched from the patterned photoresist using an etching mask. The resistor metal(3) is etched from a remaining pattern of the photoresist and conductive metal(3) using an etching mask. The photoresist is removed and a second photoresist(5) is coated to form a pattern of the second photoresist(5). A conductive metal(3) located at an upper portion of a resistor area of a remaining resistor metal(2) is exposed. The exposed conductive metal(3) is etched to form a resistor member. The second photoresist(5) is removed and a resistor metal(2) is exposed between patterns of the conductive metal(2) to form an embedded resistor. |
