1. Non-online measurement Non-online measurement tide in the integrated circuit is not soldered into the circuit, by measuring the DC resistance value between its pins and the known normal DC resistance value between the pins of the same type of integrated circuit to determine whether it is normal.

2、On-line measurement On-line measurement method is the use of voltage measurement method, resistance measurement method and current measurement method, etc., by measuring the integrated circuit in the circuit of each pin voltage value, resistance value and current value is normal, to determine whether the integrated circuit is damaged.

3. Substitution method substitution method is to use the known intact with the same type, the same specifications of the integrated circuit to replace the integrated circuit under test, you can determine whether the integrated circuit is damaged.
