Art scheme, technical solution of the present invention can solve the pin trace problem of circuit board testing, it is achieved nondestructive test.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of a kind of method to open a way in glove instrument connection that the present invention provides；
Fig. 2 is the equivalent test philosophy figure of a kind of method to open a way in glove instrument connection that the present invention provides.
Detailed description of the invention
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 carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
Seeing Fig. 1, be the schematic flow sheet of a kind of no needle mark method of testing that the present invention provides, the method includes
Following steps:
Step 101: be respectively provided with conducting resinl on the first non-conducting carrier, the second non-conducting carrier, respectively conduct electricity
Glue is connected with testing circuit respectively.
In the present embodiment, this first non-conducting carrier and the second non-conducting carrier can be, but not limited to be one non-
Thumb stall in conductive glove and forefinger fingerstall, or the most independent fingerstall.If both are same
The thumb stall of non-conductive glove and forefinger fingerstall, then testing circuit can be, but not limited to be also disposed at this glove
On, it is connected with the conducting resinl of thumb stall and forefinger fingerstall by lead-in wire.Individually refer to if both are respectively
Set, testing circuit directly can be connected with the conducting resinl on this fingerstall by lead-in wire, assembles simple, uses spirit
Live.
In the present embodiment, the conducting resinl on non-conducting carrier can use other soft conductive materials to replace,
It is best that the present invention selects conducting resinl to be because conducting resinl effect, and conducting resinl is soft, will not wipe card
Face.
Step 102: the conducting resinl of the first non-conducting carrier contacts the top line of circuit board to be detected, by the
The conducting resinl of two non-conducting carrier contacts the wiring underlayer of circuit board to be detected；Wherein, this top line and the end
Sandwich circuit is on the consolidated network of this circuit board to be detected.
In the present embodiment, owing to non-conducting carrier is glove or fingerstall, therefore may utilize people flexibly during detection
Both hands, detect on circuit board to be detected.The conducting resinl of the first non-conducting carrier is contacted electricity to be detected
The top line of road plate, contacts the wiring underlayer of circuit board to be detected by the conducting resinl of the second non-conducting carrier,
Top line, testing circuit and wiring underlayer are sequentially connected in series, form primary Ioops, it is achieved detection.
As in figure 2 it is shown, Fig. 2 is equivalence test philosophy figure of the present invention, wherein A is circuit equivalent figure, and B is circuit
Test point in plate, C is testing circuit.As it can be seen, testing circuit is by the top layer of conducting resinl with test point
Whether circuit and wiring underlayer connect, form a loop, turn on according to loop, determine testing result.
In the present embodiment, can be, but not limited to forefinger and thumb at glove and conducting resinl is set, it is also possible to
On other fingers, conducting resinl is set, as long as meeting in this step, by the top line of circuit board, testing circuit
It is connected in turn with wiring underlayer, it is achieved detect.
Step 103: the detection instruction provided according to described testing circuit, determines the inspection of described circuit board to be detected
Survey result.
In the present embodiment, testing circuit can be, but not limited to include bulb, buzzer or other signal designations
Device, and built-in power is for signal indicator.It is bright that the detection instruction of testing circuit is specifically as follows bulb
Rise, buzzer sounding or the instruction of other equivalences.When testing circuit sends detection instruction, it is determined that this detection
Point can turn on, and otherwise determines that this test point is opened a way.Concrete testing circuit and corresponding testing result can roots
The needs on border are customized factually.
Therefore, a kind of no needle mark method of testing that the embodiment of the present invention provides, at the first non-conducting carrier
Be respectively provided with conducting resinl on the second non-conducting carrier, conducting resinl is connected with testing circuit.When detection, will
The conducting resinl of the first non-conducting carrier contacts the top line of circuit board to be detected, by the second non-conducting carrier
Conducting resinl contacts the wiring underlayer of circuit board to be detected, the detection instruction provided further according to testing circuit, determines
The testing result of circuit board to be detected.Due in the present invention use conducting resinl softer, with circuit board
During wiring circuit contact, contacted with the space of a whole page by carrier, belong to contacting of face and face, use compared to prior art
