Abstract: A method of reducing whisker growths includes identifying a solder connection to be treated. The solder connection may contain one or more whisker growths. A heat source is applied at a defined temperature to the solder connection for a defined period of time sufficient to melt at least a portion of the one or more whisker growths. The heat source is removed from the solder connection prior to the melting of the solder connection.

Abstract: A method of joining a connection member to a capacitor foil using a staking tool having a tip of less than 0.030? (0.762 mm) in diameter.

Abstract: Implantable defibrillators are implanted into the chests of patients prone to suffering ventricular fibrillation, a potentially fatal heart condition. A critical component in these devices is an aluminum electrolytic capacitors, which stores and delivers one or more life-saving bursts of electric charge to a fibrillating heart. These capacitors make up about one third the total size of the defibrillators. Unfortunately, conventional manufacturers of these capacitors have paid little or no attention to reducing the size of these capacitors through improved capacitor packaging. Accordingly, the inventors contravened several conventional manufacturing principles and practices to devise unique space-saving packaging that allows dramatic size reduction.
