    Abstract: A circuit board to be attached to a support such as a case body is provided. The circuit board has formed therein a mounting hole which is so designed as to permit a thermally deformable stud to protrude through the mounting hole and also to be thermoplastically staked to mount the board to the support. A layer is printed on the board by means of silk screen printing at a distance from the mounting hole. In a case where a moisture-proof and insulating material is applied over a surface of the board, the printed layer servers to block a flow of the moisture-proof and insulating material into the mounting hole. This avoids a reduction in strength of fastening the board to the support. The printed layer may also be used in visually inspecting a failure in thermoplastic staking to mount the board to the support.

    Abstract: Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, and cortical stimulation, and many related purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow. Common flexible circuit fabrication techniques generally require that a flexible circuit electrode array be made flat. Since neural tissue is almost never flat, a flat array will necessarily apply uneven pressure. Further, the edges of a flexible circuit polymer array may be sharp and cut the delicate neural tissue. By applying the right amount of heat to a completed array, a curve can be induced. With a thermoplastic polymer it may be further advantageous to repeatedly heat the flexible circuit in multiple molds, each with a decreasing radius. Further, it is advantageous to add material along the edges. It is further advantageous to provide a fold or twist in the flexible circuit array. Additional material may be added inside and outside the fold to promote a good seal with tissue.
