MANUFACTURE OF CERAMIC MULTILAYERED WIRING BOARD

摘要

PURPOSE:To realize an excellent title board which can be laminated with no phenomema of transfer failure and breakdown of wiring patterns by manufacturing a transfer sheet with much reduced steps generated on an insulting layer by wiring patterns. CONSTITUTION:For screen printing with an insulating paste, a screen printing plate where meshes at points corresponding to wiring patterns 4 formed on a base film 3 are projected to the printing medium side or a screen printing plate where meshes at points corresponding to wiring patterns 4 formed on the base film 3 are projected to the printing medium side further with the line diameter of a mesh of the same point made larger than that of another part are used to manufacture a transfer sheet 7 with much reduced steps.
