Abstract
The present invention relates to an adjustable resistor embedded in a circuit board and a method of fabricating the same. The adjustable resistor comprises a resistor with a number of connection terminals, and a number of via holes extending to contact with the resistor. The resistive value of the resistor is variable depending on the size of the via holes, the number of the via holes, or the distance between the via holes.
