Techniques are disclosed for attaching SMDs to a flexible substrate using conductive epoxy bond pads. Each bond pad includes a set of elongated strips of conductive epoxy that are applied and cured onto the flexible substrate in an adjacent and parallel fashion. The bond pads are used to attach SMDs to the flexible substrate and also provide the conductive contacts for a printed circuit. A circuit may be printed on the flexible substrate using conductive ink that partially covers the bond pads, leaving a portion of the pads exposed. A second layer or strip of conductive epoxy may be applied over and across the exposed portions of the bond pad strips in order to attach an SMD. The number, size, and orientation of the epoxy bond pad strips may be determined by the amount of bending the flexible substrate is expected to withstand and/or the orientation of the bend.
