Abstract
The utility model relates to an open/short circuit testing fixture capable of displaying testing results, which comprises an upper fixture and a lower fixture. The lower fixture comprises a dial and a base. The open/short circuit testing fixture is characterized in that the dial is provided with LED (light-emitting diode) lamps, and the LED lamps can be respectively electrically connected with a testing result output circuit of an external open/short circuit testing device. The LED lamps have the advantages of high brightness and low energy consumption and can be directly connected with the testing result output circuit of the conventional open/short circuit testing device, and the open/short circuit testing device needs not to be changed greatly; the LED lamps are arranged on the dial, results can be displayed on the fixture for operators so as to facilitate operation of the operators, and the reading of testing results from the external open/short circuit testing device is avoided for operation of the fixture; since the LED lamps are arranged to display the open/short circuit testing results, the testing efficiency can be increased; and due to increase in the efficiency, the production cost can be reduced greatly during mass production.
Description
Technical field
The utility model relates to the electric performance test equipment of semiconductor devices, especially relates to a kind of open-short circuit tool that shows test results.
Background technology
For pcb board (being printed circuit board (PCB)), need carry out open-short circuit, its measurement jig be a kind of be a kind of unit clamp that model designs with the pcb board.During test, the operator need go up the read test result from outside open-short circuit equipment (being generally open-short circuit tester); In actual production, pcb board mostly is in batches and makes, so also being batch, open-short circuit carries out, and read test result's mode from the outside open-short circuit equipment, testing efficiency is lower.
Summary of the invention
The utility model purpose provides a kind of open-short circuit tool that shows test results, and the result of open-short circuit directly is presented on the tool, is convenient to operator's observation test result, and testing efficiency is improved.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of open-short circuit tool that shows test results, comprise tool, following tool, following tool comprises dials and base, it is characterized in that: described dials is provided with the LED lamp, and the LED lamp can be electrically connected on the test result output circuit of outside open-short circuit equipment respectively.The LED light fixture has brightness height, advantage that energy consumption is little, can directly insert the test result output circuit of conventional open-short circuit equipment, need not open-short circuit equipment is significantly transformed; The LED lamp is arranged on the dials, the result directly can be shown to the operator on tool,, and needn't again behind outside open-short circuit equipment read test result, again tool be operated for operator's operation; Therefore, the mode that the LED lamp shows the open-short circuit result is set, can improves testing efficiency; For manufacturing in enormous quantities, the lifting of this efficient can significantly reduce production costs.
In order to install, as preferably, the lamp body of described LED lamp is embedded in the dials, and the head of lamp is lower than the dials upper surface.This structure, space availability ratio is higher, and the LED lamp is not external, the damage that better, do not subject to collide with of its safety.
As the equivalent of such scheme, as preferably, the lamp body of described LED lamp is located at the sidepiece of dials.This mode is convenient to observe.
As preferably, several LED lamps are made as one group and color of the same race is set, or are set to two groups and every group a kind of color is set.The open-short circuit of pcb board, have only by with not by two kinds of test results, therefore, the LED lamp of two kinds of colors just can be represented this two kinds of test results; Obviously, these LED lamps also can be selected a kind of color for use, in order to show wherein a kind of test result, promptly show by or a kind of situation of not passing through.
Therefore, the utlity model has rational in infrastructure, be easy to characteristics such as making, especially have can on tool, show test results, beneficial effect that testing efficiency is higher.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model open-short circuit tool that can show test results;
Accompanying drawing 2 is II place enlarged drawings of accompanying drawing 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: a kind of open-short circuit tool that shows test results of the utility model, shown in accompanying drawing 1, accompanying drawing 2, it comprises tool 1, following tool, following tool comprises dials 2 and base 3, dials 2 is provided with LED lamp 22,23, and LED lamp 22,23 is electrically connected on the test result output circuit of outside open-short circuit equipment respectively.
The lamp body of LED lamp 22,23 is located at the sidepiece of dials 2 or is located in the dials 2.When the lamp body of LED lamp 22,23 was embedded in the dials 2, the head of lamp was lower than place dials 2 surfaces.
During use, the color of LED lamp 22,23 is made as redness and green respectively, does not pass through with the bright representative open-short circuit of red colored lamp, and the bright representative open-short circuit of green light passes through; Red colored lamp, green light are inserted respectively on the test result output circuit of corresponding open-short circuit tester.
Embodiment 2: LED lamp 22,23 also can be selected color of the same race for use, in order to show wherein a kind of test result, i.e. the bright representative test of lamp by or do not pass through.Other are with embodiment 1.
