New description: [New technical field] This creation involves the same-plane heterogeneous circuit board structure, which aims to provide a heterogeneous substrate at a specific position of the circuit board, which can reduce the production cost. [Prior Art] In the electronic system products, a printed circuit board (PCB) for carrying an electronic component is generally known, and a planar substrate composed of a glass fiber cloth or a soft substrate is usually used. A conductive layer is printed on the substrate. After forming a circuit on the substrate, a plurality of circuit layers and an insulating layer are laminated by a bonding process, and processed into a multilayer printed circuit board. As electronic products move toward the "light, thin and short" design concept, printed circuit boards are also moving toward small apertures, high density, multiple layers, and thin lines. Among them, multilayer printed circuit boards are a good solution for improving line density. • The = brushed circuit board surface is equipped with a plurality of electronic components, and the signals processed by the negative and negative electrons are not the same, and the speed at which the signal needs to be processed is slightly different. For example, the towel The central processing unit (CPU) usually needs to process signals at a higher speed and operating frequency, so it is necessary to provide a special environment to increase the processing speed, for example, a printed circuit board made of a low dielectric constant. A printed circuit board made of a material that can be processed in a printed circuit board, has a high transmission speed, and is processed at a higher speed, or a material having a higher heat dissipation or a higher thermal conductivity, can effectively dissipate the working heat source of the central processing unit. To maintain their work efficiency. M359898 However, if the working characteristics of some electronic components are changed, the material of the entire printed circuit board is changed, for example, changing to a low dielectric constant material or a heat dissipating or heat conducting material 'not only is the production process complicated, and the material needs to be ^ ^ Higher. [New content] In view of this, the "same-plane heterogeneous circuit board structure" is embedded in a circuit board by a heterogeneous substrate, which can reduce the production cost and meet the needs of users. The circuit board of the present invention is provided with at least one circuit board substrate. The circuit board substrate is provided with at least one embedded space, and the heterogeneous substrate different from the circuit board substrate is disposed in the embedded space. The surface of the heterogeneous substrate is in the same plane as the surface of the first circuit board substrate, and the embedding space can be disposed at a suitable position on the substrate of the circuit board as needed. The heterogeneous substrate 'for example, may be a dielectric material, a metal material, a material such as Teflon, or the internal wiring layer density is different from the circuit board substrate to reduce the cost.

The appropriate position of the material 11 'please refer to the second figure as well. 'The embedded space 12 and the heterogeneous substrate 13 can be located on the first circuit board base close to the towel center position, or at the side; or As shown in the second embodiment of the third®, the first circuit board can be mechanically first The substrate 11 is dug out of the embedded space 12 of a fixed depth, the depth of the embedded space 12 being smaller than that of the first circuit board substrate 11, and the foreign substrate u is buried in the embedded space 12. In the embodiment shown in the figure, the heterogeneous substrate 13 is the same material as the first circuit board substrate 11 (may be 卯4), and the heterogeneous substrate 13 and the first circuit board substrate 11 The density of the circuit layers is different, wherein the first circuit board substrate 11 is provided with a plated through hole 14' and is a double panel (or a multilayer board having an inner circuit layer) without any inner circuit layer. The heterogeneous substrate 13 is provided with a plated through hole 14 and a plurality of inner wiring layers 15 , and a portion of the inner wiring layer 15 is electrically connected by the plated through holes 14 , and the first circuit board substrate and the heterogeneous substrate The surface of the material 13 is provided with a conductive layer 16 (which may be a copper box), so that the heterogeneous substrate 13 can be used to increase the density of the circuit layer at a specific position of the circuit board 1; of course, the first circuit board substrate is heterogeneous and heterogeneous. A conductive material 17 may be disposed between the substrates 13. As shown in the third embodiment of FIG. 4A, the conductive material 17 may be a conductive adhesive. The conductive material 17 may constitute the upper and lower conductive layers 16 M359898. Electrically connected; if the first circuit board substrate 11 and the heterogeneous substrate 13 have an inner circuit layer 15, as described FIG. (B), the circuit board may be on the first base material 11 is formed with a through hole ore § Hai hetero junction 13 of the substrate 14 'can be turned on and each of the wiring layer 15. As shown in the fifth figure, which is a fourth embodiment of the present invention, the circuit board 1 is provided with first and second circuit board substrates 11, 111, and the first circuit board substrate 11 is provided with at least one The embedded space 12 ′ is provided with a heterogeneous substrate 13 that is different from the first circuit board substrate 11 such that the first circuit board substrate 11 and the heterogeneous substrate 13 are in the same plane, and The first circuit board substrate η and the surface of the heterogeneous substrate 13 are provided with a conductive layer 16 ′, wherein the hetero-substrate η is different from the material of the first circuit board substrate 11 , and the first circuit board substrate Η It is FR4, and the heterogeneous substrate 13 can be made of metal material, dielectric material or Teflon, and a heterogeneous substrate of different materials can be selected according to requirements, for example, a heterogeneous substrate 13 by Teflon is embedded in the first circuit. The disadvantage of the bending deformation of the overall circuit board can be improved in the board substrate η. Further, as shown in the fifth embodiment of the sixth figure, the first circuit board substrate 11 and the heterogeneous substrate 13 are press-fitted under the laminated substrate 18 to increase the line density of the integrated circuit board.
