Also include upper bracket connecting interface, lower carriage connecting interface and lead, described probe with the dynamo-electric structure that is connected of extraneous electrical measurement is: stationary positioned has the lower carriage connecting interface on the described tool lower carriage, described probe is connected with the lower carriage connecting interface by lead, and the lower carriage connecting interface is connected with extraneous electrical measurement is dynamo-electric; Described sensing chip with the dynamo-electric structure that is connected of extraneous electrical measurement is: stationary positioned has the upper bracket connecting interface on the described tool upper bracket, and described sensing chip is connected with the upper bracket connecting interface by lead, and the upper bracket connecting interface is connected with extraneous electrical measurement is dynamo-electric.
Described sensing chip is provided with the synchronous detection amplifier.
The invention has the beneficial effects as follows: the connector of the present invention by switching on probe and being connected of pad to be measured on wiring board to be measured, the connector of the tight contact measured wiring board of sensing chip by conduction makes between the connector of wiring board to be measured and the sensing chip and forms induction field again, the test value that obtains after can the electric field intensity value processing and amplifying by induction field is judged the welding conducting state of connector, grafting when effectively having avoided original measurement jig to test between connector is consumed and has been shortened the test duration, so relative cost is lower, efficient is higher.
