Abstract
A circuit board eyelet is provided for flexibly interconnecting conductive patterns on opposite surfaces of a circuit board. The eyelet comprises a flanged end, an annular body and a plurality of staking legs. The annular body is double walled and has an annular solder flow channel between the walls. The solder flow channel communicates between the staking legs and the flanged end. A solder resist layer or an elastomeric plug in the interior of the body prevents the eyelet from filling with solder, and an annulet in the walls of the annular body provides for flexing of the eyelet connecting conductive patterns through a hole in the circuit board.
