Premold lead frame combined high performance compound and copper lead frame which is suitable applied to 2nd molding. With its better thermal performance and weather resistance characteristics, premold lead frame is more competitive to organic substrate. Premold lead frame can be applied to high power voltage IC and LED lighting IC. Moreover, ,it can further collaborate with wetable flank QFN to achieve the requirement of “solder fillet visible” on automobile IC.
