Abstract:
1. A method for constructing a multilayer circuit board assembly and mounting a component tail to a trace of the assembly, comprising: constructing the multilayer circuit board assembly by forming holes in a topmost one of the layers of said assembly and plating each hole with a conductive trace; stacking the boards in a facewise stack and adhering the layers together, including leaving portions of a second board that lies immediately below said topmost board so an upper face of the second board blocks the entire cross-section of each of said holes in said topmost board; placing a component tail in each of a plurality of said holes and soldering the component tail to the plating of the hole, said step of placing including placing the component tail so its extreme lower end lies a distance above the upper face of said second board, and said step of soldering includes establishing a continuous column of solder in each hole that extends from against the upper face of said second board to above the extreme lower end of the corresponding component tail.
