Abstract
The utility model discloses a PCB circuit board, comprising two or more welding discs which form grid arrays; each welding disc is covered by anti-welding printing ink; an isolation belt is arranged outside the anti-welding printing ink; grounding copper foil is paved on the circuit board except the range covered by anti-welding printing ink and the isolation belt; and the welding disc is connected with the grounding copper foil by a connecting wire. The continuous tin phenomenon during the production of the PCB circuit board can be prevented and the quality of the PCB circuit board can be improved.
Description
Technical field
The utility model relates to electronic device, particularly a kind of PCB circuit board.
Background technology
Cover anti-solder ink on the ball grid array bonding pad in the PCB circuit board, to guarantee that pad can not covered by green lacquer, therefore, the size of anti-solder ink is greater than the size of pad; For the PCB circuit board, large-area ground connection can be reduced electrostatic interference, therefore spreads Copper Foil on pad.When arbitrary pad signal is when ground, Copper Foil is ground connection also, and then the scope that covers of anti-solder ink just can form dew copper, at this moment, the size of pad equals the size of anti-solder ink, be equivalent to have reduced and adjacent pad between distance, the company's of causing tin easily influences the quality of product.
The utility model content
The utility model provides a kind of PCB circuit board, occurs connecting tin when preventing the PCB board production, improves the quality of PCB circuit board.
The utility model provides a kind of PCB circuit board, this wiring board comprises: the pad of two or more formation grid arrays, cover anti-solder ink on each pad, anti-solder ink is provided with the isolation strip outward, except the scope of anti-solder ink and isolation strip covering, spread the ground connection Copper Foil on the circuit board, described pad links to each other with the ground connection Copper Foil by connecting line.
Further, described pad is circle, quadrangle or hexagon.
Description of drawings
Figure 1 shows that the structural representation of PCB circuit board among the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done and to be elaborated.
At first with reference to figure 1, the embodiment of the PCB circuit board that the utility model provides shown in it.In Fig. 1, a kind of PCB circuit board, this wiring board 1 comprises: the pad 11 of two or more formation grid arrays, cover anti-solder ink 12 on each pad, the anti-solder ink 12 outer isolation strip 13 that are provided with, except the scope of anti-solder ink 12 and isolation strip 13 coverings, spread ground connection Copper Foil 14 on the circuit board, pad links to each other with the ground connection Copper Foil by connecting line 15.
Further, pad is circle, quadrangle or hexagon.
Adopt the technical scheme of present embodiment, pad links to each other with the ground connection Copper Foil by connecting line, can carry out electromagnetic shielding and heat radiation to the PCB circuit board; And keep apart by the isolation strip between pad and the ground connection Copper Foil, when the pad signal is when ground, can not occur revealing copper between pad and the ground connection Copper Foil, thereby occur connecting tin, the quality of raising PCB circuit board when preventing the PCB board production.
The above only is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
