The utility model content
The technical problems to be solved in the utility model is how to overcome the existing above-mentioned defective of tool, provides a kind of simple in structure, and cost is low, not the Conductive gauge of easy damaged circuit board under test.
For achieving the above object, the utility model Conductive gauge comprises test interface, test board and covers elastic and vertical conductive layer on the test board that wherein, described elastic and vertical conductive layer is made by directed conductive material; Described test board is provided with and the corresponding contact of the solder joint of printed circuit board (PCB) to be measured, and above-mentioned contact links to each other with test interface by conductive material.So design, the probe that utilizes the elastic and vertical conductive layer to replace the needs in the existing tool manually to install is saved artificial.
As optimization, described conductive material is the Copper Foil on the base material of being fixed on through processing.When the solder joint density of circuit board under test was big, test board can contain multilayer board, and described Copper Foil can be distributed on the different plates.When the solder joint density of circuit board under test is big, test board can contain multilayer board, and described Copper Foil can be distributed in so design on the different plates, and Copper Foil is controlled processing automatically through computer, reach the purpose of connecting terminal and test interface, the more existing artificial mode of connection is quick, accurate.
As optimization, described directed conductive material is directed metallic conduction rubber, comprise rubber substrate with evenly, the vertical tinsel in rubber substrate of gathering, above-mentioned tinsel is separated from each other, its two ends end face exposes the upper and lower surface of rubber substrate respectively.
So design, tinsel even, that gather relies on rubber-covered and fixing, and the while is because the elasticity of rubber can guarantee that the tinsel two ends contact well with the contact of circuit board under test and test board respectively.During use, circuit board under test is pressed on the directed metallic conduction rubber layer, test interface is connected Test Host and can be tested.Directed metallic conduction rubber layer has good compatibility, can test multiple circuit board by changing different test boards.
As optimization, described directed conductive material is a nanometer vertical conduction cloth, comprise rubber substrate with evenly, the vertical carbon nano-tube in rubber substrate of gathering, the two ends end face of above-mentioned carbon nano-tube exposes the upper and lower surface of rubber substrate respectively.So design, conductive effect is better.
Advantage of the present utility model:
1, cancels original probe and compression spring, greatly reduced cost;
2, the conductive fiber that spread all in the rubber basic unit of elastic and vertical conductive layer evenly, gathers can be applied in the detection of various printed circuit board (PCB)s, has compatible preferably;
3, utilization replaces time-consuming manual routing through the Copper Foil of computer etching, boring, welding;
4, the abundant elasticity of utilizing rubber matrix, high conformity, conduction contact high conformity.
After adopting such scheme, that the utility model Conductive gauge has is simple in structure, easy to process, not the easy damaged circuit board, the advantage of certain compatibility is arranged, be widely used in the testing process of various printed circuit board (PCB)s.
