The invention eliminates the need for any additional connecting mechanism. The invention uses established production processes. A molding process, similar to plastic chip encapsulation, encloses the battery controlling chips and forms at the same time the body of the battery package. An additional cover, sealed to said body, closes the battery package.Field of SearchSmall lead frame (e.g., "spider" frame) for connecting a large lead frame to a semiconductor chipWith structure for mounting semiconductor chip to lead frame (e.g., configuration of die bonding flag, absence of a die bonding flag, recess for LED) Solder wettable contact, lead, or bond Wire contact, lead, or bond WITH PASSIVE DEVICE (E.G., CAPACITOR), OR BATTERY, AS INTEGRAL PART OF HOUSING OR HOUSING ELEMENT (E.G., CAP) Battery in combination with lead frame (EPO) Using strip lead frame Lead frame Encapsulating To form ohmic contact to semiconductive material HAVING INTEGRAL POWER SOURCE (E.G., BATTERY, ETC.) |
