Description
Technical field
The invention belongs to field tests, relate in particular to a kind of electric-examination tool and inspection method thereof of checking that the stiffening plate leakage is pasted on the wiring board.
Background technology
Because some wiring board such as FPC (Flexible Printed Circuit, flexible print circuit board), its quality is soft, for satisfying functional requirements such as surface mount, grafting, on some position of wiring board, posts stiffening plate.In the production, stiffening plate leaks and pastes on the inspection wiring board, and traditional method is an ocular examination, by the overlooker product is observed, judges whether stiffening plate leaks subsides.
Said method be owing to need be judged that quality can not be controlled by the people, inevitably always has error in judgement, phenomenon such as defective products occurs, causes the client constantly to complain, thereby influences producer's prestige.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of and checks that stiffening plate leaks the electric-examination tool that pastes on the wiring board, and it can judge accurately whether stiffening plate leaks subsides on the wiring board.
Another technical matters to be solved by this invention is, provides a kind of and adopts that stiffening plate leaks the method for pasting on the above-mentioned electric-examination tool inspection wiring board, can judge accurately whether stiffening plate leaks subsides on the wiring board.
In order to solve the problems of the technologies described above; The present invention provides a kind of and checks that stiffening plate leaks the electric-examination tool that pastes on the wiring board; Offer on the said wiring board and detect the hole; Have the reinforcement district on the said wiring board, said detection hole is arranged at the garbage area in said reinforcement district, but said electric-examination tool comprises and can be arranged in the whether pick-up unit of conducting of the switch pin that detects in the hole and detector switch pin; The size of the pin mark of said switch pin is less than or equal to the size in said detection hole, and said switch pin and pick-up unit electrically connect.
The present invention also provides a kind of method that the stiffening plate leakage is pasted on the above-mentioned electric-examination tool inspection wiring board that adopts, and it may further comprise the steps:
The first step: the reinforcement district of on wiring board, desiring the reinforcing plate offers and the detection hole of wiring board circuit at a distance of certain distance;
Second goes on foot: being sticked in said reinforcement district to cover the stiffening plate in said detection hole;
The 3rd step: in said detection hole, plug said switch pin;
The 4th step: judge whether the switch pin electrically conducts with said pick-up unit; When said switch pin and pick-up unit electrically conduct; Then discern the said reinforcement district stiffening plate that has been sticked, when said switch pin and pick-up unit electrically disconnect, then discern the said reinforcement district stiffening plate that is not sticked.
More specifically, said detection hole is to process through the mode of punching, boring or punching.
After in detecting the hole, plugging the switch pin of electric-examination tool, the stiffening plate if the reinforcement district has been sticked, then stiffening plate will detect the hole and block, and make the switch pin can't pass the detection hole, thereby make switch pin and pick-up unit conducting, and the electric-examination device can be discerned stiffening plate automatically and be sticked.If the reinforcing plate is leaked in the reinforcement district, the switch pin can pass and detect the hole, electrically disconnects with pick-up unit, and the electric-examination device is promptly discerned the be not sticked information of stiffening plate of this reinforcement district automatically.But whether stiffening plate leaks subsides on the said method self-verifying wiring board, and its accuracy of judgement has been avoided the problems such as error in judgement that artificial judgment is brought in the prior art.

Embodiment
Clearer for technical matters, technical scheme and beneficial effect that the present invention will be solved, below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1 and Fig. 2, a kind of wiring board, the reinforcement district 1 of its a-quadrant stiffening plate 2 (as shown in Figure 3) that need be sticked.The embodiment of the invention provides a kind of and is used to check that stiffening plate 2 leaks the electric-examination tool that pastes on the wiring board, and it comprises the switch pin 31 and pick-up unit (not shown) of electric connection.When switch pin 31 and pick-up unit electrically conduct, then discern reinforcement district 1 stiffening plate 2 that has been sticked, when switch pin 31 and pick-up unit electrically disconnect, then discern reinforcement district 1 stiffening plate 2 that is not sticked.
The embodiment of the invention also provides a kind of method that stiffening plate 2 leakages are pasted on the above-mentioned electric-examination tool inspection wiring board that adopts, and it may further comprise the steps:
The first step: as shown in Figure 2; Before the reinforcing plate 2; In the reinforcement district 1 of desiring reinforcing plate 2, offer and detect hole 11; Its processing mode can be punching, boring, or mode such as punching, and this size that detects hole 11 should can be inserted in the detection hole 11 to guarantee switch pin 31 more than or equal to the diameter of switch pin 31 pin marks.In order to prevent that detecting the wiring board that it is good that offering of hole 11 causes cloth opens circuit, detect hole 11 should with circuit on the wiring board at a distance of certain distance, will detect the garbage area 12 that hole 11 is arranged on reinforcement district 1 in the present embodiment.
Second step: as shown in Figure 3, process on the wiring board and detect after the hole, user's stiffening plate 2 that is sticked in reinforcement district 1; And ought not can occur leaking under the situation of subsides; Stiffening plate 2 is covered in and detects on the hole 11, and when reinforcement district leakage reinforcing plate occurring, then is not coated with stiffening plate on this detection hole.
The 3rd step: as shown in Figure 4, in detecting hole 11, plug the switch pin 31 of electric-examination tool, switch pin 31 electrically connects with pick-up unit, through judging whether conducting of switch pin 31, judges whether stiffening plate 2 leaks subsides.
The 4th step: judge whether switch pin 31 electrically conducts with pick-up unit.If reinforcement district 1 stiffening plate 2 that has been sticked, then stiffening plate 2 will detect hole 11 and block, and switch pin 31 can't be passed detect hole 11, thereby switch pin 31 and pick-up unit are electrically conducted, and the electric-examination tool can be discerned stiffening plate 2 automatically and be sticked; If reinforcing plate 2 is leaked in reinforcement district 1, switch pin 31 can pass and detect hole 11, electrically disconnects with pick-up unit, and the electric-examination tool is promptly discerned the be not sticked information of stiffening plate of this reinforcement district automatically.
But whether stiffening plate leaks subsides on the said method self-verifying wiring board, and its accuracy of judgement has been avoided the problems such as error in judgement that artificial judgment is brought in the prior art.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
