    摘要: A process for producing a printed wiring board, particularly an interposer for a chip size package, which comprises the steps of (1) forming an outer insulator layer 22 having outer via-holes 24 on a substrate 32, (2) forming conducting passages 31 through the outer via-holes 24 by plating with metal up to substantially the same level as the upper surface of the outer insulator layer 22, (3) forming a thin metal film 29 on the outer insulator layer 22 and on the conducting passages 31, (4) forming a conductor layer 21 in a prescribed circuit pattern on the thin metal film 29 by plating, (5) removing the part of the thin metal film 29 on which the conductor layer 21 is not formed, (6) forming an inner insulator layer 23 on the conductor layer 21, and (7) removing the substrate 32. The outer insulator layer is formed with flatness to secure good adhesion to a semiconductor chip.

    摘要: A user uses part data forming means 101 and module data forming means 102 to input the actual dimension, physical constants and mesh dividing number for fundamental shapes which are registered in advance, thereby forming parts, and then indicates the relative position between the parts to form the entire shape of an assembly of plural parts without paying attention to coincidence or non-coincidence of nodal points. Data converting means 104 divides the shape of each part thus assembled according to the indicated mesh divisional number to generate element data and nodal point data. Further, it generates a constraint equation for connecting nodal points which are non-connected between neighboring parts, and forms an analysis model 401. A finite element method analyzer 105 uses approximate calculation means 106 to approximate a non-connected nodal point displacement from a nodal point displacement of neighboring structural elements on the basis of the constraint equation.
