20150296623 | ELECTRICAL DEVICES AND METHODS FOR MANUFACTURING SAME - An electrical device for soldering to a circuit board with a solder includes a capacitor, a lead frame including a solder dam, and a solder joint electrically coupling the capacitor to the lead frame. The solder dam includes one of a physical barrier to flow or an area of reduced wettability to the solder. The solder dam is between the solder joint and the circuit board. The solder dam is on one or both of a lead portion and main portion of the lead frame. In one embodiment, the first solder dam extends substantially the full width of the first lead portion. The solder dam may be a barrier and/or include a metal oxide. A method of manufacturing the device includes soldering a lead frame to a capacitor with a solder and modifying a surface on the lead frame to include a physical barrier and/or an area of reduced wettability. | 10-15-2015 |
