Abstract
The utility model discloses a circuit board finger bias testing system, which belongs to the circuit board production field. The system comprises a circuit board and a circuit board forming punching die. A golden finger unit is arranged on the circuit board. The portion, at one side of the golden finger unit, of the circuit board is provided with a finger bias detection conductor. The finger bias detection conductor is provided with a positive connecting terminal and a negative connecting terminal. When the circuit board forming punching die is shaping the circuit board in a punching way, a punch needle on the circuit board forming punching die punches a through hole on the finger bias detection conductor. When the position deviation of the through hole on the finger bias detection conductor is larger than an allowed finger bias tolerance, an abnormal open circuit can be determined through an electric measurement tool connected on the positive connecting terminal and the negative connecting terminal of the finger bias detection conductor. Whether a product is qualified or not can be further determined. The testing system which is convenient and rapid has the production efficiency improved and the production cost lowered.
Description
Technical field
The utility model belongs to wiring board production field, is specially a kind of finger bias testing system of wiring board.
Background technology
Wiring board is widely used in electronic product field, particularly on the consumer electronics products such as mobile phone, notebook computer.Along with market is outstanding to the demand of the frivolous miniaturization of this electronic product, plug finger is more and more in the design of product.
Wiring board plug finger generally all has finger side-play amount to control requirement, when the inclined to one side tolerance of finger is strict, because wiring board sheet material exists the phenomenon of expanding with heat and contract with cold, points inclined to one side tolerance and often surpasses tolerance, and be difficult to detect and judge.Although whether golden finger rushes partially, can measure by Quadratic Finite Element measurement equipment, operating efficiency is extremely low, has also strengthened production cost, cannot meet volume production demand.
Utility model content
Partially whether the purpose of this utility model is to provide a kind of finger finger bias testing system of abnormal wiring board that can fast detecting go out.
The technical scheme that realizes above-mentioned purpose is: a kind of finger bias testing system of wiring board, comprise wiring board and wiring board molding press cutting mold, on wiring board, be provided with golden finger unit, golden finger unit is comprised of the some a row or column golden fingers that are arranged in order, it is characterized in that: on the wiring board of a side of golden finger unit, be provided with finger and partially detect electric conductor, described finger partially detects electric conductor and is just provided with, negative splicing ear, finger is just detecting electric conductor partially, negative splicing ear is used for connecting electrical measurement smelting tool, described wiring board molding press cutting mold is provided with red needle, red needle is for carrying out punching to pointing inclined to one side detection electric conductor, described finger detects on electric conductor the left and right side finger in one's hands that impacts formed punching by red needle partially, and partially to detect the distance of the corresponding left and right of electric conductor outer side edges consistent with allowed finger misalignment tolerances
Wiring board molding press cutting mold of the present utility model the profile of wiring board is carried out die-cut in, by the red needle on wiring board molding press cutting mold, at finger, partially detect on electric conductor and go out through hole, when the inclined to one side position deviation that detects the through hole on electric conductor of finger is greater than allowed finger misalignment tolerances, just can partially detect by being connected to finger electrical measurement smelting tool on the positive and negative splicing ear of electric conductor judge open circuit abnormal, whether also just can judge product is certified products, convenient and swift, improve production efficiency, reduced production cost.
Accompanying drawing explanation
Fig. 1 detects the structural representation of the wiring board of electric conductor partially with finger;
Fig. 2 is the inclined to one side structural representation that detects electric conductor of finger;
Fig. 3 detects the structural representation of electric conductor after red needle punching press for finger is inclined to one side;
Fig. 4 is the structural representation with the wiring board molding press cutting mold of red needle.
Embodiment
As shown in Fig. 1-4, the utility model comprises wiring board 1 and wiring board molding press cutting mold 2, on wiring board 1, be provided with golden finger unit 3, golden finger unit 3 is comprised of the some a line golden fingers 4 that are arranged in order, on the wiring board 1 of one side of golden finger unit 3, be provided with finger and partially detect electric conductor 5, finger partially detects electric conductor 5 and is just provided with, negative splicing ear 8, 9, finger is just detecting electric conductor 5 partially, negative splicing ear 8, 9 for connecting electrical measurement smelting tool, described wiring board molding press cutting mold 2 is provided with red needle 6, red needle 6 is for carrying out punching to pointing inclined to one side detection electric conductor 5, the distance that the left and right side finger in one's hands that impacts formed punching 7 by red needle 6 on the inclined to one side detection of finger electric conductor 5 detects the corresponding left and right of electric conductor 5 outer side edges is partially consistent with allowed finger misalignment tolerances.
Claims (1)
