摘要 |
The invention relates to a printed circuit board (1) which is wire-written inside. The inventive printed circuit board is characterised in terms of how it is produced in that after a mould has been partially filled with a curable insulating compound, electrically conductive contact elements (2, 3) are positioned and said insulating compound is then cured. The corresponding contact elements are then wired inside the board on this layer. The casting mould is subsequently further filled with curable insulating compound as far as the top of the printed circuit board, in line with the first layer (4), and the upper and lower faces are surface-ground. Other wiring levels (5, 6) filled with insulating compound can be added. Prefabricated boards which are already filled with insulating material (7) and have recesses for the contact elements can also be provided. Adhesive coatings can be used so that the wires (8) are easier to fix on the layer (s). This method can also be used to produce three-dimensional, non-planar printed circuit boards. |
