Abstract
A resistor-embedded circuit board and a method for processing the resistor-embedded circuit board are provided by the present disclosure. By opening an embedded-resistor cavity on a substrate, embedding a resistor into the embedded-resistor cavity to acquire a circuit board containing a built-in resistor. By opening the embedded-resistor cavity, it is very easy to realize high-precision control of a shape and a thickness of an embedded resistor, and realize very high-precision resistor-embedding; and it is easy to realize high-precision and massive processing. In a resistor-embedded layer, a resistor is built in a substrate. Then, in a process of pressing, a crack and a relatively large deformation will not be caused after pressing due to an irregular surface of the resistor-embedded layer, thereby improving a reliability and a quality rate of the circuit board.
