Embodiment 1
[0024] The present embodiment discloses a kind of ESD immunity testing assembly for processor chips, including: non-capacitance probes and capacitive probes respectively used to test the immunity of different pins of IC chips; and also including probe connections One end is used to connect the output end of the electrostatic discharge generator, and the other end is used to detachably connect the non-capacitive probe or the capacitive probe.
[0025] In this embodiment, the capacitance carried by the probe with capacitance is a coupling capacitance that can be connected in series between the probe connector and the single-ended signal pin of the high-speed DDR chip under test.
[0026] In this embodiment, it is equivalent to splitting the traditional system-level non-detachable probe into a probe connector and a non-capacitance probe. The circuit structure of the probe connector can be as follows: figure 1 circuit shown.
[0027] In the traditional IC ESD test, the ESD probe ...
Embodiment 2
[0042] Corresponding to the above component embodiments, this embodiment discloses an electrostatic discharge immunity test method for processor chips, including:
[0043] Step S1. Divide the pins of the tested IC chip into two types; one type is based on the non-capacitance probe for immunity test, and the other type is based on the capacitive probe for immunity test.
[0044] Step S2: Determine the type of the pin to be tested, and select the corresponding non-capacitance probe or probe with capacitance to connect to the electrostatic discharge generator via the probe connector for testing.
[0045] Preferably, the present embodiment method also includes:
[0046] Step S3, when measuring the single-ended signal of the high-speed DDR chip, select the probe with capacitance for testing, the capacitance carried by the probe with capacitance can be connected in series between the probe connector and the high-speed DDR chip under test Coupling capacitance between single-ended si...
