Abstract: Disclosed is a method of producing a printed circuit board (PCB) with an embedded resistor, in which a resistor with a desired shape and volume is precisely formed using a resistor paste so that resistance values according to a position of the PCB are uniform, thereby a laser trimming process is omitted or minimally utilized. The method has advantages in that a production time of the PCB is shortened and productivity is improved because an operation condition is rapidly set without being greatly affected by the position precision of a printing device. Other advantages of the method are that the resistor paste with a relatively uniform thickness is secured through a screen printing process, thereby easily forming the resistor and improving resistance tolerance.
