Pin Correlation Testing
Most cost effective way to determine the probability a device is functional - compares a pin's signature measurements to every other pin looking for consistent I/V characteristics. This test detects gross defects such as opens, shorts, excessive leakage, ESD damage, etc. caused by improper handling or storage.
AAA recommends a minimum of 20 samples and at least 10% of lots > 200 pieces be subjected to Continuity Testing. If one or more parts fail Continuity Testing, the entire lot should be tested.
