Circuit board with asymmetrical structure and method for fabricating the same |
摘要 |
A circuit board with an asymmetrical structure and a method for fabricating the same are proposed. A core circuit board is provided, with a build-up structure being formed on a side of the core circuit board, and a laminated structure being formed on an opposite side of the core circuit board, such that the build-up structure and laminated structure on two sides of the core circuit board can be mutually balanced. Then, the build-up process and the laminated process can be repeated on the two sides of the core circuit board to form more build-up structures and at least one more laminated structure having preferable rigidity to counteract warpage of the core circuit board caused by fabrication of the build-up structures, wherein the number of the build-up structures can be larger than the number of the laminated structures thereby forming a circuit board with an asymmetrical structure.
