    • The present invention provides a multilayer circuit board for mounting thereon a semiconductor chip or other electronic elements having electrode terminals or other connection terminals which are arranged in a grid, staggered, or close-packed manner in an improved form to enable reduction in the number of the wiring layers for lead wiring lines, thereby facilitating the production of multilayer circuit boards and providing an improved product reliability. The multilayer circuit board comprises: a base board having a mounting surface for mounting thereon a semiconductor chip and/or other electronic elements having lattice-arranged connection terminals; connection terminal pads arranged on the mounting surface to form a plane lattice corresponding to the lattice arrangement of the connection terminals and having lattice sites each occupied by one of the connection terminal pads; lead wiring lines lying on the mounting surface and having one end connected to the connection terminal pads and the other end extending outwardly from the plane lattice; and the said plane lattice having a peripheral zone including periodic vacant lattice areas formed by vacant lattice sites occupied by no connection terminal pads.
    • 本发明提供了一种多层电路板,用于在其上安装半导体芯片或具有电极端子或其他连接端子的其他电子元件,电子端子或其他连接端子以改进的形式布置成格栅,交错或紧密堆叠的方式,以减少数量 用于引线布线的布线层,从而便于生产多层电路板并提供改进的产品可靠性。 多层电路板包括:基板,其具有用于安装其上的半导体芯片的安装表面和/或具有格子排列的连接端子的其它电子元件; 连接端子焊盘,其布置在所述安装表面上以形成与所述连接端子的格栅布置相对应的平面格子,并具有各自由所述连接端子焊盘之一占据的格子部位; 引线布线位于安装表面上,其一端连接到连接端子焊盘,另一端从平面格架向外延伸; 并且所述平面晶格具有包括由没有连接端子焊盘占据的空位网格形成的周期性空格格区域的周边区域。
