Abstract
The utility model provides a pull-button type structure for connecting a pad and a through hole. The structure is mainly suitable for being used in a BGA or CPU area on a printed circuit board to connect the pad and the through hole, wherein the pad and the through hole are mutually connected by using an arc green oil bridge therebetween. According to the pull-button type structure for connecting the pad and the through hole, the number of the arc green oil bridge is arranged as one or two, and the arc green oil bridge is adopted to replace an original linear type green oil bridge to lengthen the green oil bridge between the pad and the through hole, so that the green oil bridge is not easy to be peeled off.
Description
Technical field
The utility model relates to a kind of structure that connects pad and through hole, relates in particular to a kind of pull-button formula structure that connects pad and through hole.
Background technology
As shown in Figure 1, present printed circuit board (PCB) 10, at its BGA(Ball Grid Array, the PCB of ball grid array structure) or the pad 101 in CPU zone and the green oil bridge 103 between the through hole 102 be that straight line connects, and because straight line connects apart from the shortest, as shown in the figure, the green oil bridge 103 between pad 101 and the through hole 102 is too short, can cause when reprocessing detin, this green oil bridge 103 is very easy to be stripped from.
Summary of the invention
In view of the above problems, the utility model provides a kind of pull-button formula structure that connects pad and through hole.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of pull-button formula structure that connects pad and through hole, it mainly is applicable in BGA on the printed circuit board (PCB) or the CPU zone in order to connect pad and through hole, wherein, utilize curved green oil bridge to interconnect between this pad and the through hole.
Better, the utility model provides a kind of pull-button formula structure that connects pad and through hole, and wherein, described curved green oil bridge is set to one or two.
Compared to prior art, the utility model has adopted curved green oil bridge to replace original linear pattern green oil bridge, the green oil bridge between pad and the through hole is lengthened, thereby can allow the green oil bridge be not easy to be stripped from.
Description of drawings
Fig. 1 is the schematic diagram that utilizes the bridging of linear pattern green oil to connect between existing pad and the through hole
Fig. 2 is the schematic diagram that utilizes curved green oil bridging to connect between pad described in the utility model and the through hole
Embodiment
Please refer to shown in Figure 2ly, the utility model provides a kind of pull-button formula structure that connects pad and through hole, and it mainly is applicable among the BGA or CPU zone on the printed circuit board (PCB) 20, in order to connect pad 201 and through hole 202.
Wherein, be distributed with several pads 201 and through hole 202 in BGA on the described printed circuit board (PCB) 20 or the CPU zone, utilize curved green oil bridge 203 to interconnect between this pad 201 and the through hole 202, described curved green oil bridge 203 is set to one or two, if adopt the green oil bridge 203 of two arcs, can be arranged at respectively the both sides of this pad 201 and through hole 202, and make this pad 201 interconnect with through hole 202.
Compared to prior art, the utility model has adopted curved green oil bridge 203 to replace original linear pattern green oil bridge 103, green oil bridge 203 between pad 201 and the through hole 202 is lengthened, thereby can be when reprocessing detin, allow green oil bridge 203 be not easy to be stripped from, even peeled off because of carelessness part or all of green oil bridge, tin also is not easy to flow to through hole along this arc circuit during welding.
Claims (2)
1. pull-button formula structure that connects pad and through hole, it mainly is applicable in order to connect pad and through hole, it is characterized in that among the BGA or CPU zone on the printed circuit board (PCB), utilizes curved green oil bridge to interconnect between this pad and the through hole.
2. the pull-button formula structure of connection pad according to claim 1 and through hole is characterized in that, described curved green oil bridge is set to one or two.
