According to the utility model, the apparatus utilizes an elastic contact of the testing socket to contact with the Coupon end point. Combined with the changing of the testing ports via the SSR relay transition center, the apparatus realizes the simultaneous testing of multiple TRD time domain reflectometers and the changing of the to-be-tested objects. Therefore, the apparatus realizes the rapid testing of the impedance. The apparatus of the utility model substantially raises the production efficiency and overcomes the harmful effect produced by the testing probe.
Description
[technical field]
The utility model relates to PCB testing impedance field, particularly relates to a kind of Quick Measurement PCB impedance test device.
[background technology]
Testing impedance be PCB capable in common a kind of functional test, in industry, the general impedance instrument that adopts is measured it, impedance test device comprises the parts such as data processing centre (DPC), TRD time-domain reflectomer, stube cable, test probe.General impedance plate can be reserved special test Coupon and transfer in Equivalent Plate line in the middle of edges of boards or plate, testing impedance in the past is to connect TRD time-domain reflectomer and test probe by cable, and the signal of the Coupon in test probe and PCB is connected respectively with the reference contact and measures.
There is a kind of actual transmissions line to be the PCB product of test Coupon, and has the transmission line that has in a large number impedance to require in minimum size.As by traditional method of testing with probe test one by one, not only production efficiency is extremely low, and because of the tip of test probe frequently the contact meeting to its generation weigh wounded, the harmful effect such as static.
[summary of the invention]
The utility model is intended to address the above problem and provides a kind of safe and reliable, but measures Quick Measurement PCB impedance test device accurately.
For achieving the above object, but the utility model provides a kind of Quick Measurement PCB impedance test device, this proving installation comprises data processing centre (DPC), TRD time-domain reflectomer, stube cable, SSR relay switching center and test jack, described data processing centre (DPC) connects the TRD time-domain reflectomer, this TRD time-domain reflectomer is connected with SSR relay switching center, this SSR relay switching center is provided with relay, and this relay is connected with described test jack.
Described TRD time-domain reflectomer is provided with cable socket, and described SSR relay switching center is provided with cable socket, and described stube cable is connected with cable socket on the TRD time-domain reflectomer by cable socket.
Described test jack is provided with spring contact.
The spring contact of the utility model by test jack contacts with test Coupon end points, and the conversion to test port of SSR relay switching center is tested and the tested object conversion simultaneously to realize many TRD time-domain reflectomers, reaches the purpose of quick testing impedance.Compare with impedance test device in the past, the utility model has improved production efficiency and measuring accuracy greatly, has reduced the plate face that causes because of testing impedance and has weighed wounded.
[description of drawings]
