Patent ID: 7218530

Claim:
A combination of a component conductive tail and a multi-layer circuit board assembly, the circuit board assembly including a bonded stack of a plurality of layers including a topmost layer with a stack top and a bottommost layer with a stack bottom, the circuit board assembly also including walls forming a plurality of formed holes that each extends down from said top and at least partially through a group of said layers that includes at least said topmost layer, at least one of said layers having a face carrying electrical traces thereon, and said walls of said formed holes being plated to form plated holes that each has a hole plating of conductive material that is electrically connected to one of said electrical traces, said plated holes each having a bottom that lies above said stack bottom, said component tails each have an end portion lying in one of said plated holes, and including a quantity of solder that fills each of said plated hole and that has been flowed to lie around and bond to the corresponding tail end portion and to lie against and bond to the corresponding one of said platings, wherein: each of said component tails has an extreme lower end that lies a vertical distance from an extreme lower end of the bottom of the corresponding plated hole, and the quantity of solder in each of said plurality of holes each extends from the bottom of the plated hole to above the lower end of the tail.
