<p>PURPOSE: To obtain a method for forming a via pattern in a ceramic sheet, a ceramic device created by this method, and an all-purpose tool suited for the method. CONSTITUTION: Vias 24 and 26 are arranged and further a non-conductive substance such as ceramic is selectively filled into at least one portion of the vias 24 and 26, thus creating a custom via pattern. The created via pattern is effective for manufacturing a grid transformer and a ceramic printed circuit board.</p> |
