Class Information
Number: 257/667
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Lead frame > With dam or vent for encapsulant
Description: Subject matter with a portion or portions to block encapsulant flow, typically from flowing out of a mold during an encapsulation process, or vent means (e.g., grooves in lead frame leads) to permit egress to the atmosphere for air or other gases which are inside a mold during encapsulation.
