[embodiment]
See also shown in Figure 3ly, the circuit board that the utlity model has test structure comprises an insulated substrate 10, is formed with some distributions (for example first distribution 11 and second distribution 12) on this insulated substrate 10.Wherein, this first distribution 11 is provided with a connection through hole C0, and extend some branched wirings (for example first branched wirings 111, second branched wirings 112, the 3rd branched wirings 113 on first distribution 11 ...), the end of these branched wirings 111,112,113 is respectively equipped with and connects with through hole C1, C2, C3.In addition, on the length direction of these branched wirings 111,112,113, be interval with two test end (A1 respectively, B1), (A2, B2), (A3, B3), these tests end (A1, B1), (A2, B2), (A3 B3) can expose to the surface of circuit board, and two set on same branched wirings tests are used during for test with forming a test zone between the end.In present embodiment, (A1 B1) is coupled respectively to a voltage tester unit 30 with the end in two set on first branched wirings 111 tests.And be arranged with some connections on this second distribution 12 with through holes (for example D0, D1, D2, D3 ...), these connect with through hole (C0, C1 ... D0, D1 ...) wear respectively in order to some terminals of electronic components to be provided.For example, connect with connecting a power-supply unit 14 between through hole C0, the D0, connect with connecting one first electronic component 15 (E1) between through hole C1, the D1, connect with connecting one second electronic component 16 (E2) between through hole C2, the D2, connect with connecting other electron component between through hole C3, the D3, after power-supply unit 14 was unlocked, circuit board then was under the conduction state.
See also shown in Figure 4ly, this voltage tester unit 30 is provided with two test leads 301,302, is under the conduction state at this circuit board, and two test leads 301,302 are contacted two tests simultaneously with end A1, B1.Distribution on the circuit board can be the copper metal, and the copper metal is conductor, and then test (being assumed to be U with the voltage between end A1, the B1
A1B1) can be very little, thereby this voltage tester unit 30 can be by an amplifier 31 and a voltmeter 33 coupling back formation, so that read magnitude of voltage.The enlargement ratio of supposing this amplifier 31 is 100, and the magnitude of voltage that voltmeter 33 is read is U
Out, then by calculating as can be known U
A1B1=U
Out/ 100.
, be example please with first branched wirings 111 in conjunction with consulting Fig. 3 and shown in Figure 5, the resistance value R of test between end A1, the B1
A1B1=σ * L/A (wherein, σ is the resistivity of copper, and L is the length between A1, the B1, and A is the area of section of first branched wirings 111).When producing circuit board, only need length and area of section between definite A1, the B1 can determine R
A1B1Size.
Hence one can see that, passes through I
A1B1=U
A1B1/ R
A1B1Thereby, obtain the size of current that flows through first electronic component 15, so that the staff judges comparison.In like manner, also be applicable to test with the end (A2, B2), (A3 B3) waits the test at place, to obtain the size of current that flows through second electronic component 16 or other electron component.
