Specific embodiment

The utility model is described in further detail for explanation and specific embodiment below in conjunction with the accompanying drawings.

As shown in Figure 3 to Figure 4, the PCB pad structures of a kind of compatible circuit, including wiring board and steel mesh, the wiring board It is equipped with the first circuit 1 and second circuit 2, first circuit 1 is equipped with the first dew copper pad 3 of non-lid green oil, and described the Two circuits 2 are equipped with the second dew copper pad 4 of non-lid green oil, and the first dew copper pad 3, second reveals copper pad 4 and is disposed adjacent, The steel mesh is equipped with brush tin cream perforate 6, and the brush tin cream perforate 6 is located at the described first dew copper pad 3, second and reveals copper pad 4 On, the first dew copper pad 3 and second reveals copper pad 4 and is respectively positioned within the brush tin cream perforate 6 and is opened with the brush tin cream Hole 6 is non-intersect.

As shown in Figure 3 to Figure 4, first circuit 1, the upper and lower ends of second circuit 2 are respectively equipped with shakedown copper 5.

As shown in Figure 3 to Figure 4, the brush tin cream perforate 6 is equipped with tin paste layer, and the first dew copper pad 3, second reveals copper Pad 4 is connected by the tin paste layer, when having brushed tin cream and crossing stove, since the first dew copper pad 3, second reveals between copper pad 4 Away from close, and tin cream is entirely to cover, so left and right dew copper pad can be connected by tin.

It is the compatible circuit design of one-to-two in Fig. 5, network C is connected what either network D was connected with network E with network E Compatible design.When network C is needed to be connected with network E, the dew copper pad of C and E is only brushed in steel mesh design, does not brush the dew copper of D networks Pad ensures that network C and the pad of network E are connected by scolding tin after crossing stove, and is not attached to the pad of network D.

It is designed in Fig. 6,7 for one point three of compatible circuit, wherein above and below figure is the design method of two kinds of pads, The design method that can certainly have other similar.

It is designed in Fig. 8,9 for one point four of compatible circuit, wherein above and below figure is the design method of two kinds of pads, The design method that can certainly have other similar.

A kind of PCB pad structures of compatible circuit provided by the utility model can pass through the change design of pad, Ke Yijian The circuit compatibility for holding 1 road to multichannel designs.0 ohm of material can be saved and save cloth plate suqare on plate.

A kind of PCB pad structures of compatible circuit provided by the utility model are mainly used in PCB design cabling field, It solves to reduce cloth plate suqare as far as possible during pcb board design compatible circuit；It is generally often compatible to need to increase by two 0 ohm of electricity all the way Resistance, is not only that increased resistance has cost, in addition can also occupy PCB goods of furniture for display rather than for use areas, at least to occupy the encapsulating face of two 0201 Product.

The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, several simple deduction or replace can also be made, should all be regarded To belong to the scope of protection of the utility model.
