Abstract
The utility model discloses a printed circuit board, this printed circuit board's components and parts distribute according to circuit function and rather than the contact of other return circuits and set up in the region of difference, and the physics is kept apart between each region, supplies power respectively to each part of mutual isolation to adopt the reference ground of isolation completely. The normal work of each functional circuit is guaranteed, the interference is effectively prevented from being connected in series, and the anti-interference capability of the PCB is improved.
Description
Technical field
The utility model relates to printed circuit board (PCB) (PCB, Printed Circuit Board) components and parts and lath layout, is meant the distribution form of components and parts and copper-clad plate bar on a kind of electric welding machine control circuit board especially.
Background technology
The control circuit board of electric welding machine be positioned at the welding machine body interior, and welding machine inside exists various high frequencies and other interference signal as the control of inverter type welder, and operational environment is more abominable.So these interference signals are very easily disturbed the operate as normal of pcb board, make its normal function be difficult to performance.In addition, the bigger device of part caloric value is arranged on the pcb board, caloric value is bigger in the work, if temperature is too high, will influence some operate as normal to the relatively responsive device of temperature.
The utility model content
In view of this, the utility model proposes a kind of printed circuit board (PCB), improve the antijamming capability of pcb board, and then improve product quality.
The printed circuit board (PCB) that provides based on above-mentioned purpose the utility model, its components and parts according to circuit function and with the contact method in other loops, distributing is arranged at different zones, physical isolation between each zone, each several part to mutual isolation is powered respectively, and adopts the reference ground that isolates fully.
Heater members on the described printed circuit board (PCB) is away from the temperature sensor setting.
Heater members on the described printed circuit board (PCB) is concentrated on the basis that guarantees fully heat radiation and is provided with.
CPU control section on the described printed circuit board (PCB) is isolated with sample circuit, external control circuit.
Distance between physically-isolated each zone on the described printed circuit board (PCB) is not less than 8 millimeters.
From above as can be seen, the printed circuit board (PCB) that the utility model proposes by adopting the method for zoning, has guaranteed each functional circuit operate as normal in design, has prevented sealing in of interference effectively, has improved the antijamming capability of pcb board.And, make it concentrated relatively, and, guaranteed the reliability of whole plate work away from the relatively more responsive device of those temperature by further on the basis that the heater members that guarantees on the pcb board fully dispels the heat.
Description of drawings
Fig. 1 is that the printed circuit board (PCB) of the utility model preferred embodiment adopts the schematic diagram of zoning;
Fig. 2 is that the printed circuit board (PCB) of the utility model embodiment adopts the schematic diagram of the relative centralized layout of heater members.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to shown in Figure 1, components and parts in the present embodiment on the pcb board 100 according to circuit function and with the contact method in other loops, distribute respectively and be arranged at different zones, between each zone, adopt physically-isolated method to keep apart mutually, part to mutual isolation is powered respectively, and adopts the reference ground that isolates fully.So promptly guarantee the integrality of signal, further prevented sealing in of interference again effectively.
Particularly than the CPU control section 2 that is easier to be interfered, then make its fully with sample circuit 1, external control circuit isolation 3.Set up the isolation strip 4 of all insulation between the each several part, and guarantee sufficient distance, generally be no less than 8 millimeters at least.
In addition, the bigger device of part caloric value is arranged on the pcb board 100, caloric value is bigger in the work, and too high temperature can influence some operate as normal to the relatively responsive device of temperature.Therefore further heater members is tried one's best away from the temperature sensor setting among the utility model embodiment.Preferred embodiment is referring to shown in Figure 2, and pcb board 100 makes it concentrated relatively on the basis that heater members 5 is fully dispelled the heat, and away from those devices that is affected easily, to guarantee the reliability of whole plate work.
Description of the present utility model provides for example with for the purpose of describing, and is not exhaustively or with the utility model to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present utility model and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment that have various modifications that the utility model design is suitable for special-purpose.
Claims (5)
1. a printed circuit board (PCB) (100), it is characterized in that, components and parts on this printed circuit board (PCB) (100) according to circuit function and with the contact method in other loops, distribution is arranged at different zones, physical isolation between each zone, each several part to mutual isolation is powered respectively, and adopts the reference ground that isolates fully.
2. printed circuit board (PCB) according to claim 1 (100) is characterized in that, the heater members (5) on the described printed circuit board (PCB) (100) is away from the temperature sensor setting.
