Leadframe Configuration to Enable Strip Testing of SOT-23 Packages and the Like

摘要

A sacrificial lead and a common lead hold a die paddle of each integrated circuit SOT-23 package to a leadframe within a strip of leadframes after isolating signal leads from the leadframe. Strip testing of most devices in the SOT-23 three and five lead packages may then be performed. The common lead may be at the center of an edge of the SOT-23 package. Also the common lead may be any one of the leads of the SOT-23 package. In addition the sacrificial lead may be at the center of an opposite edge of the SOT-23 package.
