The test of electrostatic protection element, be exactly according to device parameters, special measurement jig is used to carry out correspondence test to the protective capacities of electrostatic protection element, in test process, need the device of test often smaller, and pin is meticulous, the earth terminal of device or power pins cannot be connected to ground or power supply again, cause static gun contact discharge directly to test device, making cannot the quality of paying attention electrostatic protection element.
Utility model content
In order to overcome the defect of prior art, provide a kind of structure simple, easy to use, test accurate, adaptable electrostatic test equipment, the utility model discloses a kind of protecting component for electrostatic discharge test fixture.
The utility model reaches goal of the invention by following technical solution:
A kind of protecting component for electrostatic discharge test fixture, comprise test cell, it is characterized in that: test cell comprises lead-in wire, test contact, pad, build-out resistor and bleeder resistance, test contact is fixed on one end of connector lug, the other end of lead-in wire is electrically connected one end of build-out resistor and one end of bleeder resistance respectively by pad, the other end electrical connection power supply of build-out resistor, the other end electrical connection earth terminal of bleeder resistance;
The quantity of test cell is no less than 2, and one end that in each test cell, build-out resistor is connected with power sourced electric is electrically connected all mutually, and in each test cell, one end of bleeder resistance and earth terminal electrical connection is electrically connected all mutually.
Described protecting component for electrostatic discharge test fixture, is characterized in that: build-out resistor and bleeder resistance all select variable resistor, and the resistance of test contact is not more than 5 Ω.
When the utility model uses, detected element is welded on pad, release supply voltage and ground, build-out resistor and the bleeder resistance corresponding according to the test voltage of the corresponding Selecting parameter electrostatic tester of protective element, detected element, use contact discharge test probe, test probe withstands on test contact, can start test.
The utility model is based on basic circuit elements, and structure is simple, is easy to use, and obtains the impedance matching and electrostatic leakage path wanted by regulating resistance parameter and ground circuit, add dirigibility and operability.The utility model is relative to existing protective element protective capacities method of testing, and the test duration of consumption obviously reduces, and improves the reliability and stability of element test, also improves the testing efficiency of electrostatic protection element to a certain extent simultaneously.
The beneficial effects of the utility model are: structure is simple, easy to use, and test is accurate, strong adaptability.
