Abstract
The utility model discloses a circuit board, comprising a substrate, a welding pad, connecting lines, and an obstructing block disposed on the substrate. The substrate is provided with location holes. The substrate is also provided with a main control chip. The location holes are provided with reinforcing pads along axial directions. Copper coil is connected around the welding pad. The obstructing block is installed between the welding pad and the copper coil around the welding pad. When the circuit board is used, the circuit board is convenient to install through the location holes. Through the reinforcing pads, the holes are protected, thereby preventing the holes from being damaged by stress in manufacturing and using processes of the holes, and further improving utilization rate of a product. The circuit board is simple in structure, convenient in use and installation, simple in operation, and is safe and reliable.
Description
Technical field
The utility model relates to a kind of circuit board.
Background technology
Along with multimedia, the integrated application of systems technology such as communication and computer, no matter be desktop computer or notebook at present, its function is increasing, the circuit design of calculator main frame is also more complicated, notebook particularly, for more assembly is set in limited space, the design of elements on circuit board also becomes even more important with arrangement, and existing circuit board, do not adopt the location hole design of exact position for the shell of coupling, the installation site is science not, do not meet the requirement of present versatility small-size display, poor practicability is not easy to user installation in dismounting, location hole is damaged by stress can in manufacturing and use, and these all can bring loss to the user.
The utility model content
Technical problem to be solved in the utility model provides a kind of through hole of protecting, thereby prevents that through hole from damaged by stress in manufacturing and use, and then increases the utilization rate of product; and it is simple in structure; use, easy for installation, simple to operate, have the circuit board of safe and reliable effect.
The utility model is achieved through the following technical solutions:
A kind of circuit board of the present utility model, comprise substrate, weld pad and connecting line, and be arranged on barrier blocks on the substrate, described pad installation is on substrate, described substrate is provided with location hole, also is provided with main control chip on the described substrate, and described location hole is equipped with vertically strengthens pad, described weld pad periphery is connected with Copper Foil, and described barrier blocks is installed between weld pad and the described weld pad Copper Foil on every side.
As technical scheme preferably, described weld pad links to each other with Copper Foil by connecting line.
As technical scheme preferably, described weld pad adopts the mode of welding to fixedly connected with substrate.
As technical scheme preferably, described location hole is provided with more than four.
The beneficial effect of a kind of circuit board of the utility model is: by set location hole; make circuit board easy for installation, by set reinforcement pad, can protect through hole; thereby prevent that through hole from damaged by stress in manufacturing and use, and then increase the utilization rate of product.It is simple in structure, and use, easy for installation, simple to operate has safe and reliable effect.
