Resistor-capacitor measurement module applied to flying probe tests

Abstract

The invention belongs to the technical field of flying probe tests, and particularly discloses a resistor-capacitor measurement module applied to the flying probe tests. The resistor-capacitor measurement module comprises a resistor test module, a capacitor test module and a control processing module. The resistor test module is used for testing a resistor value between same networks on a test substrate, and the capacitor test module is used for testing a capacitor value between different electric networks to the earth on the test substrate. The control processing module is respectively connected with the resistor test module and the capacitor test module, and is used for generating sine waves. The frequency and amplitude of the sine waves both are controllable, and the control processing module is used for controlling switching and electing between functions of the resistor test and the capacitor test, testing gear selection and probe assembly selection, receiving test data of the resistor test module and the capacitor test module for processing, and outputting test result data. The resistor-capacitor measurement module can be imbedded in a flying probe test device main system, realizes automatic probe selection test through software control, is quick in gear selection, accurate in test, and has the advantages of being high in test speed, and short in response time. The test accuracy can meet the technological requirements of the flying probe test.

Description

technical field [0001] The invention relates to the technical field of flying probe testing, in particular to a resistance-capacitance module for flying probe testing. Background technique [0002] Flying probe test equipment is the key equipment for semiconductor post-packaging.
