Embodiment
Described in Fig. 1-Fig. 3,
A kind of switching circuit board for circuit board testing, comprise: switching circuit board 3, be arranged on switching circuit board socket 4 on switching circuit board, switching circuit board plug 6 and wiring 5, the described switching circuit board socket 4 being arranged on switching circuit board is arranged on the one side of switching circuit board 3, the described switching circuit board socket 4 being arranged on switching circuit board is arranged on the another side of switching circuit board 3, and the signal pins of switching circuit board socket 4 is connected by wiring 5 with the signal pins on switching circuit board plug 6.
At described switching circuit board 3, there is the one side of socket install one with fixing feet and expose the panel 7 of socket.
In described wiring 5, every signal link is isometric, and according to the signal type of transmission, different live widths and distance between centers of tracks is set.
The test cpu pcb of take is example,
Before installation:
First, define plug model that cpu pcb is corresponding and the definition of each leg signal, as+5V signal, GND signal, 32 address wires, 32 data lines etc.;
Secondly, in switching circuit board 3, by on the switching circuit board socket 4 being arranged on switching circuit board+signal wire of 5V signal, GND signal widens, then the pin that is arranged on the switching circuit board socket 4 on switching circuit board is connected to the corresponding pin of switching circuit board plug 6,32 address wires on the switching circuit board socket 4 being arranged on switching circuit board, 32 data lines keeping parallelisms are isometric, wide, by being arranged on the pin of the switching circuit board socket 4 on switching circuit board and the pin on switching circuit board plug 6, couple together;
After switching circuit board 3 processes, design, with the panel 7 of fixing feet, is arranged on the lower surface of switching circuit board 3.
During installation:
Circuit-under-test plate 9 is arranged on switching circuit board 3, as shown in Figure 3, the switching circuit board socket 4 being arranged on switching circuit board is docked with circuit-under-test plate plug 8, switching circuit board plug 6 is docked with the instrumentation PCB socket 2 on special test equipment circuit board 1.
