Abstract
The utility model discloses a line-connecting neilsbed testing machine, relating to an electronic testing device for contact neilsbed; the utility model comprises a plurality of electronic testing circuit boards; wherein, a plurality of springs and testing needles are positioned on the upper surface of the boards, and a plurality of testing solder joints and testing needles are arranged on the surface of the boards; the utility model is characterized in that a plurality of short welding lines are arranged on the springs and testing needles; the length of the short welding lines are equal to the distance between the electronic testing circuit board to the testing solder joint. The utility model has the advantages of improving the contact performance of the testing points, simplifying the manufacture techniques, maintenance and fixing measures, and freely assembling testing sizes and then designing local low or high density combination in order to reduce the equipment cost.
Description
Technical field:
The utility model relates to a kind of line-connection type needle-bar test machine, and it belongs to a kind of electronic test equipment of contact needle-bar.
Background technology:
Existing Electronic Testing Technology mainly contain following several in, the needle-bar, combined type testing jig, traditional Wound-rotor type test machine, contact pin or the seated connection that both be independent of testing apparatus touch the mode test machine.The shortcoming of tradition Wound-rotor type test machine: patrix is often upper and lower to be moved, and patrix forms unreliable the connection with the electronics line, easily broken string.Finish ten hundreds of lines is installed, cost and mounting process all are difficult to accomplish.Counterdie does not move, and line is too many, and difficulty is installed.If broken string will bring great difficulty to maintenance.The shortcoming that socket (pin) way of contact test machine exists is: the contact contact, and resistance is big, long oxidation on metal surface of time, loose contact; Needle-bar is an integral body, and volume is big, weight is big.Needle-bar is counted from 1.5 ten thousand---80,000 points, and so heavy needle-bar and so many contact point, contraposition and maintenance be difficulty relatively.Adopt the socket mode, such connector is a non-standard component, die sinking customized, the cost height.
Summary of the invention:
It is a kind of simple in structure that the purpose of this utility model is to provide, handling ease, and test is accurate, and testing cost is low, and can be according to the line-connection type needle-bar test machine of the needs aggregate erection of testing.
The purpose of this utility model is achieved in that
A kind of line-connection type needle-bar test machine, it comprises several Electronic Testing circuit boards, be provided with some springs or testing needle in the upper surface of described Electronic Testing plate, be provided with the test solder joint on the surface of described Electronic Testing circuit board, described some springs or testing needle are provided with short bonding wire, described short bonding wire.
The length of described short bonding wire equates with the distance of Electronic Testing circuit board to the test solder joint.
Described short bonding wire is thin conductive electric wire.
The some springs or the testing needle that are located at the upper surface of described Electronic Testing plate can be fixed by a fixed mount of pressing close to circuit board.
The utility model adopt can be crooked arbitrarily short bonding wire connection testing needle or spring to testing circuit board, it is one that needle-bar engages with electron plate.Every short bonding wire separate connection does not have the contraposition requirement to the test machine integrated circuit board; The test machine integrated circuit board connects testing needle, constitutes the little needle-bar module of cutting apart, but the independent assortment test size, and can be designed to local low-density, local high density combination reduction equipment cost.Therefore the utility model improves the contact performance of test machine test point, simplifies production technology, and maintenance and installation method reduce equipment cost.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is the unitized construction synoptic diagram of multimode of the present utility model
Embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2 below, the utility model be further detailed:
Constituting of single module of the present utility model at an Electronic Testing plate 4 and the some springs or the testing needle 1 that are located at the upper surface of Electronic Testing plate 4.Usually according to the needs of test, the combination of several Electronic Testing circuit boards 4 will be arranged, as shown in accompanying drawing 2,5 are a single module, 6 combinations for a multimode group being combined into.Be provided with some springs or testing needle 1 in the upper surface of described Electronic Testing plate 4, be provided with test solder joint 3 on the surface of described Electronic Testing circuit board 4, on described some springs or testing needle 1, be provided with short bonding wire 2, described short bonding wire 2; The length of described short bonding wire 2 equates with the distance of Electronic Testing circuit board 4 to test solder joint 3; Described short bonding wire 2 is thin conductive electric wire.
Because fine rule can be crooked arbitrarily, is welded to easily on the solder joint of electronics integrated circuit board.Adopt fine rule connection testing needle or spring to testing circuit board, it is one that needle-bar engages with electron plate.For double/quad density or more highdensity test machine, all be easier to guarantee to connect.The a plurality of same needle-bars and the module of electronics integrated circuit board assembly formation constitute a big test needle-bar.Such separate type needle-bar, changeable, conveniently be combined into arbitrary dimension.And when maintenance, local damage is as long as take out a module, weld next root fine rule and spring or catapult pin, just can keep in repair, and as long as in a module, look for line, normally 128 lines, and the line that just searching damages on a PCB wiring board, so very easily easily.Realize that electronics integrated circuit board and needle-bar unite two into one, the installation of test machine is brought great convenience.Requirement to physical construction is simplified, and volume and weight all has reduction in various degree.
In order to help the fixing of spring or testing needle more, the some springs or the testing needle 1 that are located at the upper surface of described Electronic Testing version can be fixed by a fixed mount 7 of pressing close to circuit board by some springs or a testing needle 1 of pressing close to solid edition upper surface of circuit board.
