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.
Claims14
An eyelet for flexibly interconnecting conductive patterns on opposite surfaces of a circuit board comprising a flanged end, an annular body connected to said flanged end, and a plurality of staking legs extending from said annular body, said body having spaced inner and outer walls presenting an annular solder flow channel between said staking legs and said flanged end, an annulet formed therein between said staking legs and said flanged end and a layer of solder resist adherent the interior of said inner wall.
An eyelet for flexibly interconnecting conductive patterns on opposite sides of a circuit board comprising a flanged end, an annular body connected to said flanged end, and a plurality of staking legs extending from said annular body, said body having spaced inner and outer walls presenting an annular solder flow channel between said staking legs and said flanged end, an annulet formed therein between said staking legs and said flanged end, and an elastomeric plug adherent the interior of said body.
