    Abstract: A process for producing a printed circuit board is disclosed, in which the following steps are sequentially conducted:
    (1) a step for dispersing in at least one of the mediums of water and an organic solvent
    (A) 95 to 20% by weight of a styrene polymer having a syndiotactic structure, (B) 5 to 80% by weight of a fibrous filler having a fiber length of 1 to 50 mm, and (C) 0.1 to 30 parts by weight of at least one of a binder and a binding fiber in proportion to 100 parts by weight of the total amount of said components (A) and (B), to make a slurry having a concentration of 0.5 to 100 g/l, (2) a sedimentation step of the dispersed solids in said slurry, (3) a step for removing at least one of the mediums of water and an organic solvent in the slurry by filtration and drying and molding the residue, (4) a step for melting with heating and pressure forming the molded product, and (5) a step for providing a metal layer on the molded article. The printed circuit board obtained by the process is excellent in impact resistance, heat resistance, mechanical strength and size stability as well as dielectric properties.

    Abstract: Embodiments of the present invention provide method and apparatus of restoring probes attached to the manipulator in a control environment (e.g. vacuum chamber of an focus ion beam) without a need to open the vacuum chamber. Another embodiment of the present invention teaches construction and application of various shapes of nanoforks from a nanoneedles array inside a FIB vacuum chamber. In another embodiment, the present invention teaches edition and correction of completed and oxide-coated circuit boards by re-nano-wiring using nanoneedles of a nanoneedles array (as nanowire supply), contained in the same controlled space. In this embodiment, individual nanoneedles in a nanoneedle array are manipulated by a manipulator and placed in such a way to make electrical contact between the desired points.
