Abstract
A test-used PCB having an in-series circuit involved with a join test action group (JTAG) signal is provided. A first JTAG connection interface and a second JTAG connection interface are configured on test circuit boards. Test circuit boards can be seriously connected with each other through the first JTAG connection interface and the second JTAG connection interface. Therefore, the efficiency of providing series test circuit boards, reducing TAP controller and JTAG port may be achieved.
