Abstract
The utility model discloses a kind of PCB safeguard structure, comprise PCB (1), described PCB (1) is provided with cabling Copper Foil (2), copper foil (3) and via hole (4); Described cabling Copper Foil (2) and via hole (4) are equipped with and are coated with at least one deck solder mask (5); Spacing between described cabling Copper Foil (2) and copper foil (3) is at least 0.6mm; Spacing between described via hole (4) and copper foil (3) is at least 0.6mm.Above-mentioned PCB safeguard structure can be avoided cabling Copper Foil and copper foil, be leaked electricity between cabling Copper Foil and via hole.
Description
Technical field
The utility model relates to printed substrate technical field, is specifically a kind of PCB safeguard structure.
Background technology
In electronic product, the application of battery widely.Battery is arranged in PCB usually, and powered battery loop is printed on printed wiring board usually, the printed conductor of via hole then normally between each layer of connection PCB wiring board.Due to powered battery loop cabling Copper Foil be connected and the copper foil of self-contained battery, spacing between the cabling Copper Foil in powered battery loop and via hole too small, therefore after the biochemistry corrosion of PCB for a long time by environment, easily leak electricity between cabling Copper Foil and copper foil, cause battery power consumption to strengthen, thus affect useful life and the product reliability of battery.So, for these reasons, urgently need a kind of PCB safeguard structure avoiding leaking electricity between cabling Copper Foil and copper foil, to solve the problem.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of PCB safeguard structure can avoided cabling Copper Foil and copper foil, leak electricity between cabling Copper Foil and via hole.
The technical solution of the utility model is, provide a kind of PCB safeguard structure, comprise PCB, described PCB is provided with cabling Copper Foil, copper foil and via hole; Described cabling Copper Foil and via hole are equipped with and are coated with at least one deck solder mask; Spacing between described cabling Copper Foil and copper foil is at least 0.6mm; Spacing between described via hole and copper foil is at least 0.6mm.
Described solder mask is also coated with one deck silk-screen layer.
After adopting above structure, the utility model compared with prior art, has the following advantages:
The utility model PCB safeguard structure is equipped with and is coated with at least one deck solder mask on cabling Copper Foil and via hole, and this solder mask effectively prevent cabling Copper Foil and the via hole problem exposed because of corrosion.Described cabling Copper Foil and via hole are equipped with and are coated with at least one deck solder mask; Spacing between described cabling Copper Foil and copper foil is at least 0.6mm; Spacing between described via hole and copper foil is at least 0.6mm.By increasing cabling Copper Foil and copper foil, distance between cabling Copper Foil and via hole, and reduce the possibility of conducting electricity between the two.By the improvement of above structure, make not easily to leak electricity between cabling Copper Foil and copper foil, ensure that the normal use of battery, thus ensure that useful life and the product reliability of battery.
As improvement, described solder mask is also coated with one deck silk-screen layer.Can more effectively prevent cabling Copper Foil and copper foil by this layer of silk-screen layer, leak electricity between copper foil and via hole, thus further ensure useful life and the product reliability of battery.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model PCB safeguard structure.
Shown in figure 1, PCB, 2, cabling Copper Foil, 3, copper foil, 4, via hole, 5, solder mask, 6, silk-screen layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of PCB safeguard structure of the utility model, comprise PCB 1, described PCB 1 is provided with cabling Copper Foil 2, copper foil 3 and via hole 4, and these are prior art, are not described in detail in this; Described cabling Copper Foil 2 and via hole 4 are equipped with and are coated with at least one deck solder mask 5, in the present embodiment, cabling Copper Foil 2 and via hole 4 are equipped with two-layer solder mask 5.
Spacing between described cabling Copper Foil 2 and copper foil 3 is at least 0.6mm; Spacing between described via hole 4 and copper foil 3 is at least 0.6mm.This distance is through testing crew and obtains through test of many times, both ensure that the volume of PCB, also reduces the possibility of leaking electricity between them.
Described solder mask 5 is also coated with one deck silk-screen layer 6.Can more effectively prevent cabling Copper Foil and copper foil by this layer of silk-screen layer 6, leak electricity between copper foil and via hole, thus further ensure useful life and the product reliability of battery.
Below only just most preferred embodiment of the present utility model is described, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.In every case the various change done in the protection range of the utility model independent claims is all in protection range of the present utility model.
Claims (2)
