Background technology
To miniaturization, high integrated, high performance trend development, the volume of electronic devices and components is more and more littler day by day for modern electronic product, and density is more and more higher.As the printed panel of the interconnected carrier of electronic devices and components, the density of its density and chip is closely bound up, and its number of plies is more and more, and wiring density is more and more higher.Continuous increase along with wiring density, distance between the test point is microcosmicization day by day also,---0.127mm 0.05mm pitch number of test points per square inch is 500---2500,0.05mm---0.025mm ultra fine pitch number of test points per square inch is 2500---5000.Along with the requirement to detection means improves day by day, current printed board producer wire wound and the needle-bar formula testing apparatuss that adopt more, obviously lag behind the needs that reach high-density test flexibly fast, flying probe equipment is applied in the production by increasing printed board producer.Presently used flying probe tester, base is provided with lower guideway and stepper motor, be provided with the test column that has mechanical arm and chaining pin between last lower guideway, each test column is driven by the stepper motor corresponding with it respectively, stepper motor is connected with transmission shaft, the transmission shaft two ends are provided with up and down active synchronization wheel, up and down the active synchronization wheel by up and down synchronously band be connected with passive and synchronous wheel the up and down, be with synchronously up and down to be connected with test column.This flying probe tester has finer pitch, is not subjected to mesh restraint, tests characteristics such as flexible, that speed is fast, rate of false alarm is low.But in the rigid transmission of transmission shaft, because transmission shaft is elongated, make the wheel of active synchronization up and down at transmission shaft two ends can't guarantee concentricity 0.05mm, transmission shaft radially also can't guarantee 0.05mm in addition, more than two kinds of reasons cause test column under band effect synchronously up and down, top and bottom to occur to swing, produce rotatablely moving of crank type, swinging appears in the test column that causes having mechanical arm and chaining pin, because of physical construction causes error, reduce measuring accuracy.
The utility model content
The technical problems to be solved in the utility model just provide a kind of can be because of physical construction does not cause error, the flying probe tester that measuring accuracy is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the base that is provided with lower guideway and stepper motor, be provided with the test column that has mechanical arm and chaining pin between last lower guideway, described stepper motor is provided with duplex active synchronization wheel, duplex active synchronization wheel is inboard by big ring-like synchronous band and duplex engaged wheel inboard, the first simply connected engaged wheel, the second simply connected engaged wheel is connected, the duplex active synchronization wheel outside is connected with the duplex engaged wheel outside by little ring-like synchronous band, and big ring-like synchronous band and little ring-like synchronous band fix with test column respectively.
Its additional technical feature is: described test column is four, and two in front, and two in the back.
Flying probe tester provided by the utility model compared with prior art, cancelled transmission shaft, duplex active synchronization wheel has been installed on stepper motor, duplex active synchronization wheel is inboard to be connected with duplex engaged wheel inboard, the first simply connected engaged wheel, the second simply connected engaged wheel by big ring-like synchronous band, the duplex active synchronization wheel outside is connected with the duplex engaged wheel outside by little ring-like synchronous band, and big ring-like synchronous band and little ring-like synchronous band fix with test column respectively.Like this, big ring-like synchronous band connects duplex active synchronization wheel inboard, duplex engaged wheel inboard, the first simply connected engaged wheel and the second simply connected engaged wheel, and between the first simply connected engaged wheel and the second simply connected engaged wheel with test column on/lower end is fixed.Little ring-like synchronous band connects the duplex active synchronization wheel outside and the duplex engaged wheel outside, and fixes with the following/upper end of test column between duplex active synchronization wheel and duplex engaged wheel.When stepper motor rotated, simultaneously to a direction motion, during the stepper motor rotating, test column, mechanical arm and chaining pin back and forth movement were realized test job under big ring-like synchronous band and little ring-like synchronous band acting in conjunction in the top and bottom of test column.Above-mentioned test process changes rigid transmission into flexible transmission, has avoided the error that causes because of physical construction, has solved side pin vibration problems, and measuring accuracy improves greatly, has reduced transmission torsion, has improved test speed.
