Abstract:
A surface mount component for connection to pads on a surface, comprising:a body; one or more rows of leads connected to the body and elongated in a direction perpendicular to the direction of the row, sufficiently long in relation to a width of the leads that if solder volumes on the leads is sufficient, the solder bulges if reflowed without being in communication with the surface pads; and solder on the leads with sufficient volume to form bulges on the leads if the solder is reflowed before placement without communication with the surface pads, and wherein the relationship between said volume of solder and the dimensions of said leads is: VP(W)2Ã—L=0.3&it;â€ƒ&it;to&it;â€ƒ&it;0.5â€ƒwhere: VP=Volume (cubic mm) of solder metal, W=Width (mm) of lead, and L=Length (mm) of lead.
