A method of assembling an implantable electrode array from a coupon (108) formed from plastically deformable material. Layers of material are disposed on the coupon to form the electrodes (48) and conductors (62) of one or more electrode arrays. Sections of the coupon on which the electrodes and conductors are removed, along with the electrodes and conductors to form the electrode arrays. The removed sections of the coupon thus function as plastically deformable carriers (74) for the arrays (40).
