Circuit board assembly with pads and connection lines having same resistance value as the pads and impedance matching method

Abstract

A circuit board assembly includes a circuit board, at least one pad formed on the circuit board, and at least one connection line. Each of the at least one connection line includes a connection end connected to a respective one of the at least one pad and has the same resistance value as the respective pad.

What is claimed is: 
     
         1 . A circuit board assembly comprising:
 a circuit board;   at least one pad positioned on the circuit board; and   at least one connection line, wherein each of the at least one connection line comprising a connection end connected to a respective one of the at least one pad and having the same resistance value as the respective pad.   
     
     
         2 . The circuit board assembly of  claim 1 , wherein the resistance value of each pad is 50 ohm. 
     
     
         3 . An impedance matching method for impedance matching between a pad and a connection line, the method comprising:
 providing a circuit board and one of the pad and the connection line;   obtaining a resistance value of the one of the pad and the connection line via a multimeter;   fabricating the other one of the pad and the connection line, the pad and the connection line having the same resistance value;   positioning the pad on the circuit board; and   connecting a connection end of the connection line to the pad.
