Technical field
The present invention relates to technical field of electronic equipment, especially a kind of equipment that the resistance value of SMD inductance is tested.
Background technology
At present, impedance, Q value surveying instrument that isoparametric measurement is used, the instrument of these class miniature electronic components and parts of SMD inductance had four test leads, each test lead all has screen layer to link to each other with casing, also can be referred to as the five terminal test.These five test leads are respectively:
HD: current drives high-end (HIGH DRIVE)
LD: current drives low side (LOW DRIVE)
HS: voltage detecting high-end (HIGH SENSE)
LS: voltage detecting low side (LOW SENSE)
⊥: shielding ground end
The purpose that shielding ground end uses is to reduce over the ground impact and the reduction electromagnetic interference (EMI) of stray capacitance.Described HD, HS and LD, LS end should be connected at the detected element lead-in wire during measurement, forms complete four-terminal measurement, with reduce to go between and tie point on the impact (especially loss) of test result.Particularly when low impedance element is detected, drive end and test side should be separated the lead end that is connected to element and add tested impedance to prevent lead resistance.In other words, be connected with the detected element lead end again after described HD, HS and LS, LD end can not be connected to each other first, otherwise will increase test error.Correct operation is: described HD is connected with HS at detected element lead-in wire place be connected with the one end, described LS is connected with LD at detected element lead-in wire place be connected with the other end.
Because the SMD inductance output that my company produces is larger, in order to ensure the quality of products, need to carry out to the SMD inductance of each production impedance, the isoparametric measurement of Q value, test, therefore, original manual test mode is too slow, can't satisfy a large amount of product test requirements
