Abstract
The utility model discloses a PCB (Printed Circuit Board) with a plurality of isolated areas, which comprises a first circuit area and a second circuit area, wherein the first circuit area and the second circuit area are mutually and physically isolated; and the first circuit area and the second circuit area are supplied power separately and adopts completely isolated reference grounds. The PCB with the plurality of isolated areas has the benefits that the areas which are isolated mutually and physically are adopted, and interference of easily-disturbed circuits is avoided by adopting separate power supply and completely isolated grounds for grounding, so that the stability of the PCB can be ensured.
Description
Technical field
The utility model relates to electronic applications, relates in particular to a kind of multizone and isolates printed substrate.
Background technology
Be distributed with the components and parts of multiple performance on the printed substrate, the mutual interference of meeting phase causes unstable properties between its parameter frequency or the power supply.Especially between analog circuit and the control circuit, be easy to generate interference signal between high-tension circuit and the low-voltage circuit, make that the operational environment of CPU is more abominable.In addition, have on the pcb board part caloric value big during, caloric value is bigger in the work, if temperature is too high, will influence some to temperature relatively responsive during operate as normal.
The utility model content
The technical problem that the utility model mainly solves provides a kind of antijamming capability that improves pcb board, and then the multizone of enhancing product performance is isolated printed substrate.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of multizone to isolate printed substrate, described wiring board comprises mutually physically-isolated first line areas and second line areas, power supply and adopting reference isolated fully respectively between described first line areas and second line areas.
The beneficial effects of the utility model are: the printed substrate that does not adopt multizone to isolate that is different from prior art is easy to generate the defective of interference, the utility model adopts mutual physically-isolated zone, and adopt power supply respectively and fully isolator ground connection solved interference between the circuit of easy interference, guaranteed the stability of pcb board.
Further, by heating area of isolation and thermo-responsive area of isolation are set, and will generate heat area of isolation and thermo-responsive area of isolation be away from setting, guaranteed that the electronic devices and components in the thermo-responsive zone can operate as normal, and the thermal source that is unlikely to be subjected to heating region disturbs.
