Abstract
The utility model relates to a double-faced circuit board which has a bonding pad structure, comprising a multilayer circuit board. The double-faced circuit board comprises a first face and a second face, and the first face and the second face both have the circuit structure. The double-faced circuit board is provided with a weld leg hole (1), and the weld leg hole (1) is provided with a welding pad (2) only on the second face. The double-faced circuit board with the bonding pad structure of the utility model is provided with the welding pad at the weld leg hole only at one side of the circuit board, thereby saving the soft soldering. As the circuit board that has double-sided connection is needed, the utility model is additionally provided with a connecting hole having smaller diameter, so as to realize the circuit connecting of the other side by installing a double-faced welding pad (4) covered by green oil at the connecting hole (3), thereby saving the soft soldering and facilitating the circuit board to be disassembled conveniently.
Description
Technical field
The utility model relates to double-sided PCB, more particularly, relates to a kind of double-sided PCB that has pad structure.
Background technology
The pad of traditional double-sided circuit board component is two-sided.That is: two-layer up and down all have pad, and be coated with metal in the middle of the pad hole, as shown in Figure 1 and Figure 2, is respectively the structural representation of the circuit board front and back of prior art.In process of producing product, can waste a large amount of scolding tin like this, increase production cost of products, in the maintenance maintenance of product,, probably can cause the monoblock circuit board damage to scrap because the dismounting components and parts are very inconvenient.
The utility model content
The technical problems to be solved in the utility model is, at the above-mentioned defective of prior art, provides a kind of double-sided PCB that has pad structure.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of double-sided PCB that has pad structure, comprise multilayer circuit board, described double-sided PCB comprises first and second that is provided with circuit structure, described double-sided PCB is provided with the leg hole, and pad is only located to be provided with at second in described leg hole.
In the double-sided PCB that has a pad structure described in the utility model, described connecting hole locates to be provided with the two-sided pad of connecting hole at first and second.
In the double-sided PCB that has a pad structure described in the utility model, the two-sided pad of described connecting hole is covered by green oil.
Implement the double-sided PCB that has pad structure of the present utility model, have following beneficial effect: because the double-sided PCB that has pad structure of the present utility model, only pad is set, has saved scolding tin at the place, leg hole of the one side of circuit board.For the circuit board of the two-sided connection of needs, the less connecting hole of diameter is set in addition again, by being set in the connection hole, the two-sided pad that covers with green oil realizes that the circuit of one side connects in addition, saved soldering, and made the convenient dismounting of circuit board.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the circuit board Facad structure schematic diagram of prior art;
Fig. 2 is the back of circuit board structural representation of prior art;
Fig. 3 is the Facad structure schematic diagram that has the double-sided PCB of pad structure of the present utility model;
Fig. 4 is the structure schematic diagram that has the double-sided PCB of pad structure of the present utility model;
Fig. 5 is the Facad structure schematic diagram that the double-sided PCB that has pad structure of the present utility model has connecting hole;
Fig. 6 is the structure schematic diagram that the double-sided PCB that has pad structure of the present utility model has connecting hole.
Embodiment
In conjunction with Fig. 3 to Fig. 6 the structure that has the double-sided PCB of pad structure of the present utility model is described.
The double-sided PCB that has pad structure of the present utility model comprises double-sided PCB, described double-sided PCB comprises first and second that is provided with circuit structure, described double-sided PCB is provided with leg hole 1, in order to save soldering, first of circuit board is provided with pad 2 at 1 place, leg hole, as shown in Figure 4, at second 1 place, leg hole of circuit board pad is not set, as shown in Figure 3.First can be that the front of circuit board also can be the reverse side of circuit board.
First circuit connects and can directly realize that by the pad 2 that is arranged on first its circuit connects as shown in Figure 5.In order to realize that second circuit connects, the 1 other connecting hole 3 that is provided with in the leg hole, the diameter of connecting hole 3 is littler than the diameter in leg hole 1, second circuit connects on the pad that can earlier circuit be connected first, connecting hole 3 by correspondence is incorporated into second then, the circuit that can finish second connects, and its circuit connects as shown in Figure 6.Locate to be provided with connecting hole pad 4 at connecting hole 3 at first and second, connecting hole pad 4 can be covered by green oil, because the diameter of connecting hole 3 is little more a lot of than the diameter of connecting hole 3, can save soldering like this, and makes that the dismounting components and parts are more convenient.
Claims (4)
1. double-sided PCB that has pad structure, comprise multilayer circuit board, described double-sided PCB comprises first and second that is provided with circuit structure, and described double-sided PCB is provided with leg hole (1), it is characterized in that pad (2) is only located to be provided with at second in described leg hole (1).
2. the double-sided PCB that has pad structure according to claim 1 is characterized in that, described leg hole (1) is other to be provided with connecting hole (3), and the diameter of described connecting hole (3) is less than the diameter in described leg hole (1).
