COPPER STRAP OF LEADFRAME

摘要

PURPOSE: A copper strap of a leadframe is provided to precisely perform an alignment process and a bonding process and to fix a strap part firmly by making a copper strap built as one body with the leadframe. CONSTITUTION: A die(30) of a semiconductor device mounted on the leadframe(10) is bonded by the copper strap(20) of the leadframe. A connection axis(21) is connected to both sides of a leadframe body. The strap part(23) pressurizes and fixes the die mounted on the leadframe, capable of performing a seesaw motion by using the plurality of connection axes as a medium. The copper strap includes the connection axis and the strap part to be built as one body with the leadframe.
