Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lead frame substrate wherein a mount component is not affected by heat and solder cracks are not generated in soldering by inserting a lead of the mount component to a hole of a conductor metal which is subjected to burring processing. SOLUTION: In the lead frame 1 wherein the surface of a conductor metal 2 is coated with a non-conductor of a resin 3 and the resin 3 is removed only in a part whereto a lead 7 of the mount component 6 to be packaged is soldered, a burr 5 is formed in an opposite side of a packaging side of the mount component 6 by shaping a hole 4 for inserting the lead 7 by carrying out burring for a removal part of the resin 3. The lead 7 is inserted to the hole 4 and the burr 5, and soldering is carried out to envelop the lead 7, the hole 4 and the burr 5. COPYRIGHT: (C)2005,JPO&NCIPI
