Abstract
The utility model discloses a PCB board. The board comprises a substrate. A breakline is arranged on the substrate. The breakline comprises a vertical breakline and a transverse breakline. The vertical breakline and the transverse breakline form grid shape distribution on the substrate. By using the PCB board of the utility model, technical problems are solved; machinability of the PCB board is increased so that the PCB board can be broken without needing a specific cutting tool under the condition that an intensity and a mechanical property are guaranteed; operation difficulty of PCB board processing is reduced; processing efficiency of the PCB substrate is effectively increased; and subsequent processing cost of the PCB board is reduced.
Description
Technical field
The utility model relates to a kind of printed circuit board (PCB), particularly a kind of pcb board.
Background technology
Printed circuit board, claim printed circuit board (PCB), printed substrate again, be called for short printed board, English PCB (printed circuit board) or the PWB (printed wiring board) of being called for short is base material with the insulation board, is cut into certain size, at least has a conductive pattern on it, and cloth porose (as component hole, fastener hole, plated-through hole etc.), be used for replacing installing the chassis of electronic devices and components in the past, and realize interconnecting between the electronic devices and components.Because this plate is to adopt electron printing to make, so be called as " printing " circuit board.Custom claims that " printed wiring board " is that " printed circuit " is inapt, because do not have " printed component " and wiring is only arranged in printed board.It is the important electron parts, is the supporter of electronic devices and components.
In today of electron trade high development, the acting on of pcb board seems in the electron trade and becomes more and more important.Standardization, miniaturization and wiring density are high to be pcb board day to show important advantage.Simultaneously because the base material of printed circuit board (PCB) has higher intensity, in the process of cutting apart, need to use specific cutting tool, the cost height adopts the mode of cutting to also have the generation of pollutions such as noise dust simultaneously, can influence health of operators and contaminated environment.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of pcb board under the prerequisite of its proof strength and mechanical property, need not specific cutting tool, can be fractureed, reduced the difficulty of pcb board cutting processing, improve the efficient of PCB substrate division processing effectively, reduced the subsequent machining cost of pcb board.
The disclosed pcb board of the utility model comprises substrate, and substrate is provided with broken line, and broken line comprises vertical broken line and horizontal broken line, and vertically broken line becomes grid-shaped to distribute with horizontal broken line at substrate.
A kind of improvement of the disclosed pcb board of the utility model, broken line is made up of the hole slot that is arranged in the perforation substrate on the same straight line.
Another of the disclosed pcb board of the utility model improved, and the hole slot that connects substrate is manhole or square through hole or bar shaped through slot.
The substrate of the disclosed pcb board of the utility model by pcb board be provided with latticed arrangement setting by the hole slot that connects substrate forms horizontal broken line and vertical broken line, be convenient to when needed the substrate of pcb board is carried out break process, to adapt to environment for use to the needs of pcb board shape, reduced the difficulty of PCB cutting and separating processing, reduce the cost of division processing, improved the production cost of production efficiency and pcb board.
Description of drawings
The structural representation of Fig. 1, the disclosed pcb board of the utility model.
Accompanying drawing is indicated tabulation:
1, substrate; 2, vertical broken line; 3, horizontal broken line
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand following embodiment and only be used for explanation the utility model and be not used in restriction scope of the present utility model.Need to prove, word " preceding ", " back ", " left side ", " right side ", the "up" and "down" used are described below refer to the direction among the width of cloth figure, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometric center.
As shown in Figure 1, the disclosed pcb board of the utility model comprises substrate 1, and substrate 1 is provided with broken line, and broken line comprises vertical broken line 2 and horizontal broken line 3, and vertically broken line 2 distributes in 1 one-tenth grid-shaped of substrate with horizontal broken line 3.
A kind of improvement of the disclosed pcb board of the utility model, broken line is made up of the hole slot that is arranged in the perforation substrate on the same straight line.
Another of the disclosed pcb board of the utility model improved, and the hole slot that connects substrate is manhole or square through hole or bar shaped through slot.
The substrate of the disclosed pcb board of the utility model by pcb board be provided with latticed arrangement setting by the hole slot that connects substrate forms horizontal broken line and vertical broken line, be convenient to when needed the substrate of pcb board is carried out break process, to adapt to environment for use to the needs of pcb board shape, reduced the difficulty of PCB cutting and separating processing, reduce the cost of division processing, improved the production cost of production efficiency and pcb board.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme of being made up of above technical characterictic combination in any.
