Further, described the first non-conductive carrier and described the second non-conductive carrier are respectively thumb stall and the forefinger fingerstall in non-conductive gloves.
Further, described conducting resinl is separately positioned on described thumb stall and forefinger fingerstall, and described testing circuit is arranged on described non-conductive gloves, is connected respectively with the conducting resinl on conducting resinl and forefinger fingerstall in thumb stall.
Further, described the first non-conductive carrier is fingerstall independently, and described the second nonconductor carrier is fingerstall independently.
Further, on described testing circuit, be provided with bulb or hummer;
Detection that described testing circuit provides indication, is specially: the shinny or hummer sounding of described bulb.
Therefore, implement the embodiment of the present invention, there is following beneficial effect:
A kind of no needle mark method of testing that the embodiment of the present invention provides arranges respectively conducting resinl on the first non-conductive carrier and the second non-conductive carrier, and conducting resinl is connected with testing circuit.In the time detecting, the conducting resinl of the first non-conductive carrier is contacted to the top line of circuit board to be detected, the conducting resinl of the second non-conductive carrier is contacted to the wiring underlayer of circuit board to be detected, then the detection providing according to testing circuit indication, determine the testing result of circuit board to be detected.Because the conducting resinl adopting in the present invention is softer, in the time contacting with the circuit of circuit board, contact with the space of a whole page by carrier, belong to contacting of face and face, adopt the technical scheme of mobile flying needle than prior art, technical solution of the present invention can solve the pin trace problem of circuit board testing, realizes nondestructive test.
Accompanying drawing explanation
Fig. 1 is a kind of schematic flow sheet with the method for opening a way in gloves instrument connection provided by the invention;
Fig. 2 is a kind of equivalent test philosophy figure with the method for opening a way in gloves instrument connection provided by the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1, be the schematic flow sheet of a kind of no needle mark method of testing provided by the invention, the method comprises the following steps:
Step 101: on the first non-conductive carrier, the second non-conductive carrier, conducting resinl is set respectively, each conducting resinl is connected with testing circuit respectively.
In the present embodiment, it is thumb stall and the forefinger fingerstall in non-conductive gloves that this first non-conductive carrier and the second non-conductive carrier can be, but not limited to, or is respectively independently fingerstall.If the thumb stall that both are same non-conductive gloves and forefinger fingerstall, testing circuit can be, but not limited to also be arranged on these gloves, is connected with the conducting resinl of thumb stall and forefinger fingerstall by lead-in wire.If both are respectively independent fingerstall, testing circuit can directly be connected with the conducting resinl on this fingerstall by lead-in wire, and assembling is simple, uses flexibly.
In the present embodiment, the conducting resinl on non-conductive carrier can adopt other soft conductive materials to replace, and the present invention selects conducting resinl to be because conducting resinl effect is best, and conducting resinl is soft, can not wipe card face.
Step 102: the conducting resinl of the first non-conductive carrier is contacted to the top line of circuit board to be detected, the conducting resinl of the second non-conductive carrier is contacted to the wiring underlayer of circuit board to be detected; Wherein, on this top line and the wiring underlayer consolidated network in this circuit board to be detected.
In the present embodiment, because non-conductive carrier is gloves or fingerstall, therefore can utilize people's both hands flexibly while detection, on circuit board to be detected, detect.The conducting resinl of the first non-conductive carrier is contacted to the top line of circuit board to be detected, the conducting resinl of the second non-conductive carrier is contacted to the wiring underlayer of circuit board to be detected, top line, testing circuit and wiring underlayer are together in series successively, form a loop, realize and detecting.As shown in Figure 2, Fig. 2 is the present invention's equivalence test philosophy figure, and wherein A is circuit equivalent figure, and B is the check point in circuit board, and C is testing circuit.As shown in the figure, testing circuit is connected with top line and the wiring underlayer of check point by conducting resinl, forms a loop, according to whether conducting of loop, determines testing result.
In the present embodiment, can be, but not limited to, at forefinger and the thumb of gloves, conducting resinl is set, also can on other fingers, conducting resinl be set, as long as meet in this step, the top line of circuit board, testing circuit and wiring underlayer are connected in turn, realize and detecting.
Step 103: the detection providing according to described testing circuit is indicated, determines the testing result of described circuit board to be detected.
In the present embodiment, testing circuit can be, but not limited to comprise bulb, hummer or other signal meter (SM)s, and built-in power is for signal meter (SM).The detection indication of testing circuit is specifically as follows that bulb lights, the indication of hummer sounding or other equivalences.Detect indication when testing circuit sends, determine that this check point can conducting, otherwise determine this check point open circuit.Concrete testing circuit and corresponding testing result can be customized according to the actual needs.
Therefore a kind of no needle mark method of testing that the embodiment of the present invention provides arranges respectively conducting resinl on the first non-conductive carrier and the second non-conductive carrier, conducting resinl is connected with testing circuit.In the time detecting, the conducting resinl of the first non-conductive carrier is contacted to the top line of circuit board to be detected, the conducting resinl of the second non-conductive carrier is contacted to the wiring underlayer of circuit board to be detected, then the detection providing according to testing circuit indication, determine the testing result of circuit board to be detected.Because the conducting resinl adopting in the present invention is softer, in the time contacting with the circuit of circuit board, contact with the space of a whole page by carrier, belong to contacting of face and face, adopt the technical scheme of mobile flying needle than prior art, technical solution of the present invention can solve the pin trace problem of circuit board testing, realizes nondestructive test.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
