Planar flying probe tester and PCB transmission method

Abstract

The invention provides a planar flying probe tester and a PCB transmission method. The planar flying probe tester includes a material receiving mechanism, consisting of a material take-out mechanism for taking qualified and unqualified PCBs under test out of a probe bed testing material table; a loading mechanism, consisting of a feeding table, a feeding mechanical arm and a feeding conveying device; a flying probe testing host, consisting of a test host conveying device and a test device; and a laying-off mechanism, consisting of a PASS material table, an NG material table, a laying-off mechanical arm and a laying-off motion device. The material receiving mechanism and a probe bed are connected in a seamless manner, the feeding mechanism conveys the PCBs under test to the flying probe testing host and tests the electrical properties thereof, then the laying-off mechanism places the qualified or unqualified PCBs onto the PASS material table or the NG material table, and the test is completed. The test stability and accuracy are high, the retest efficiency is greatly improved, and the scrap rate of the PCBs and the retest cost are also reduced.

Description

technical field [0001] The invention relates to the field of testing machines, in particular to a planar flying probe testing machine and a method for transmitting a PCB board. Background technique [0002] At present, with the rapid development of PCB technology, the development of circuit boards in the direction of light, thin and short is accelerating. Artificial electrical test. When the Pad size of the test board is below 2mil and the density of the Pad pitch is 6mil, coupled with the eccentric holes in the process, the general or professional needle bed cannot meet the test requirements. Only the flying probe test can be overcome by changing the test point in the system. Test the limits of distance. However, the flying probe testing machine can only be used in small batch production. However, when the circuit board is relatively dense, the failure rate of the general-purpose or special-purpose needle bed machine will increase. If the general-purpose or special needl...

However, the flying probe tester can only be used in small batch production

However, when the circuit board is relatively dense, the failure rate of the general-purpose or special-purpose needle bed machine will increase. If the general-purpose or special needle-bed machine is used for retesting, the efficiency will be low and it will take a lot of time. Joint testing can improve efficiency and reduce costs
