Abstract:
A flexible flat cable includes a cable main body and a pair of reinforcing plates. The cable main body includes a pair of resin films and a plurality of linear conductors. The linear conductors are exposed with respect to one of the resin films to form longitudinally extending electrical terminals. Each of the reinforcing plates has a fixed end section. The fixed end sections are fixedly coupled to end portions of the cable main body on the other of the resin films, respectively. The fixed end sections define a pair of bending lines such that the end portions of the cable main body are bendable relative to a middle portion of the cable main body to form acute corners between the end portions and the middle portion, respectively.

Disclosed is a printed circuit board having an embedded electronic component, including a metal substrate having a first cavity formed in a thickness direction and a support plate integrated with one side of the metal substrate and formed in the first cavity. Thereby, a method of manufacturing such a printed circuit board is also provided. When manufacturing the printed circuit board having an embedded electronic component, there is no need for an additional member including support tape to seat the electronic component, thus simplifying the manufacturing process and reducing lead time, thereby improving productivity.

The board comprises reinforced area (10a) reinforced against external stress, bending area (10c) bending easier than the reinforced area (10a) by external stress, and a stress relaxation area (10b) provided in area between the reinforced area (10a) and the bending area (10c), bending easier than the reinforced area (10a) but not easier than the bending area (10c) by the external stress, and relaxing the stress carried from the bending area (10c) to the reinforced area (10a).
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.
