Abstract
The utility model provides a circuit board testing fixture for testing the pliability of the circuit board, which comprises a base for loading the circuit board; a base board is arranged on the base in a detachable way; the circuit board is fixed between the base and the base board; a pressure device is rotatablely arranged on the base board, and the pressure device which penetrates through the base board is butted with the circuit board. In addition, the pressure device is connected with a counting device for measuring the movement distance of the pressure device. Thus, the utility model can be used for testing the circuit board on a production line to produce tin cracking when the circuit board is bent to some degree; accordingly, the quality of the circuit board can be controlled to perfection.
Description
Technical field
The utility model is about a kind of circuit board testing jig, but particularly relevant for a kind of circuit board testing jig of flexible degree of testing circuit board.
Background technology
Along with the prosperity day by day of electronics technology, the function of electronic system and application be variation day by day also.It is complicated that the making of relative electronic circuit more becomes, and in the electronic circuit production run in order to get rid of the mistake of non-research and development design, for example bad short circuit that is caused of print circuit plates making or broken string, perhaps product line group process of assembling careless mistake and problem (as the part wrong plug) of causing etc., all need a reliable and effective method of testing to pinpoint the problems as early as possible, in order to avoid in follow-up manufacturing and test process, waste extra manufacturing cost for getting rid of these problems.So utilize Automatic Test Equipment come subtest widely electronics firm's employing to increase productivity.
Yet, known testing tool all is at the design of the electronic circuit on the circuit board wrong test the whether, but ignored the problem that circuit board itself may cause, because when the pliability of circuit board itself is not good, circuit board suffers slight bending, promptly may cause the scolding tin on the circuit board to break, and then cause the disabler on the circuit board.
Summary of the invention
In view of this, the purpose of the utility model is that a kind of circuit board testing jig is provided in order to address the above problem, but the pliability of its testing circuit board.
In the utility model, a kind of circuit board testing jig is provided, in order to testing circuit board, comprising: in order to the base of bearer circuit plate; Be arranged on the substrate on the base removably, it is fixed between base and the substrate circuit board; And be arranged on pressue device on the substrate rotationally in the mode of passing substrate, itself and circuit board butt.
Again in the utility model, pressue device with the opposite face of circuit board bearing surface on be provided with a plurality of scales.
In the utility model, base is provided with a plurality of backstays again.
In the utility model, substrate is respectively equipped with screw on the position corresponding to backstay again.
In the utility model, provide a kind of circuit board testing jig again,, comprising: in order to the base of bearer circuit plate in order to testing circuit board; Be arranged on the substrate on the base removably, it is fixed between base and the substrate circuit board; Be arranged on pressue device on the substrate rotationally in the mode of passing substrate, itself and circuit board butt; And the counting assembly that is connected with pressue device, in order to measure the displacement of pressue device.
In the utility model, pressue device is provided with one first gear again, and counting assembly is provided with second gear with first gearing mesh.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the exploded view of first embodiment of the circuit board testing jig of the utility model;
Fig. 2 A is the outboard profile of first embodiment of the circuit board testing jig of the utility model, and wherein circuit board does not suffer downforce;
Fig. 2 B is the outboard profile of first embodiment of the circuit board testing jig of the utility model, and wherein circuit board suffers downforce;
Fig. 3 A is the exploded view of second embodiment of the circuit board testing jig of the utility model;
Fig. 3 B is the vertical view of second embodiment of the circuit board testing jig of the utility model.
Embodiment
See also Fig. 1, first embodiment of the circuit board testing jig 100 of the utility model is made of a base 1 and a substrate 3, and base 1 is provided with four backstays 11; Substrate 3 is provided with four screws 31 and a pressue device 32.
The other end of pressue device 32 (with the opposite face of circuit board 2 bearing surfaces) on be provided with several scales 321, allow the user can learn the distance that moves down of pressue device 32.
See also Fig. 2 A, 2B, the operating process of the circuit board testing jig of the utility model is described; As circuit board 2 is shown in 2A figure, be arranged between base 1 and the substrate 3, the screw 111 that this moment, backstay 11 passed pilot hole 21, screw 31 and backstay 11 screws togather and an end and circuit board 2 butts of pressue device 32, and the signal line on the circuit board 2 22 is connected on the display of icon not; The operator rotates pressue device 32 it is moved down afterwards, and this moment, circuit board 2 promptly shown in 2B figure, suffered to produce after the downforce crooked.
Above-mentioned test process does not have certain standard as yet, and its fundamental purpose is that the product that the inventor of the utility model is set up in order to ensure the circuit board quality are protected process, and therefore certain test procedure is not arranged.For instance, after the operator can test the circuit board of some in advance, obtain one and can guarantee the standard value of circuit board quality (the signal transmission can not interrupted, can not produced solder crack), even the each pressue device of operator moves down this standard value afterwards, whether the quality of checking circuit board is normal.
By this, the test of circuit board can more be tending towards complete.
Second embodiment of the circuit board testing jig 200 of the utility model is shown in 3A, 3B figure, and it is made of a base 1 and a substrate 4, and wherein the formation of base 1 is identical with first embodiment, therefore is marked with identical symbol and omits its explanation.
When the operator rotates the rotation section 421 of pressue device 42, first gear 422 also rotates thereupon, and second gear 433 of drive counting assembly 43, the rotation of second gear 433 then rotates pointer 431 by connecting rod 432 thereupon, therefore the operator can be by the variation of pointer 431 at scale 434, and learn the distance that moves down of pressue device.
The difference of the present embodiment and first embodiment is: set up a counting assembly, so that more convenient during operator's reading numerical values.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; anyly be familiar with this operator; in the spirit and scope that do not break away from the utility model; when can doing a little change and retouching, so the protection domain of the utility model attached claims person of defining after looking is as the criterion.
