Abstract
The utility model relates to a flexible circuit board for flat mini-size motor, which comprises a circuit board base plate which is provided with symmetrical printed circuits in left and right, a pad and a cover layer which are respectively used to connect a motor brush and a power input down-lead, and is characterized in that the center portion of the cover layer is provided with an opening for exposing the pad corresponding to the pad which connects the motor brush and the power input down-lead, and the edges of the opening or the edges of the cover layer respectively cover the periphery of the pad. Therefore, the pad can not tilt to break when conducting the soldering, and the connection of the pad and the printed circuits is reliable, and the quality of the flat mini-size motor is effectively guaranteed. The flexible circuit board for flat mini-size motor has the advantages of simple structure, reasonable design, simple operation, time conservation, high efficiency and reduced cost.
Description
Technical field
The utility model relates to a kind of flat micromachine, particularly a kind of flexible PCB that is used for flat micromachine.
Background technology
Circuit design in the flat micromachine adopts flexible PCB usually, the substrate of flexible PCB is provided with and covers the copper printed wire, the end of printed wire is respectively equipped with the pad that connects motor brush and power supply input lead, and is provided with coverlay and covers in printed wire; In the existing structure, coverlay directly is connected with pad.At present, each producer is in order to satisfy environmental requirement, on the flexible circuitry panel material is selected, adopt the halogen material, because having compared the halogen material with the bonding force between the copper coin, the halogen flexible circuit board substrate descends 30%, make the copper coin and the cohesive force between the flexible PCB that form pad descend, easily cause its connecting portion perk, fracture, influence the electrical property of flexible PCB.If take corresponding remedial measure, can make that again production technology is more complicated, reduce production efficiency, and can make consistency of product relatively poor.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of simple in structure, work simplification, the flexible PCB that is used for flat micromachine of dependable performance.
The technical scheme that the utility model adopted is for achieving the above object: a kind of flexible PCB that is used for flat micromachine, comprise circuit board substrate, which is provided with symmetrical printed wire, be respectively applied for the pad and the coverlay that connect motor brush and power supply input lead; It is characterized in that the corresponding core that connects the pad of motor brush and power supply input lead of described coverlay is provided with the opening that appears pad, described edge of opening or coverlay edge cover in the pad peripheral part respectively.
The beneficial effects of the utility model are: it is simple in structure, and is reasonable in design, easy and simple to handle, and the time-saving and efficiency reduces cost.When carrying out welding operation, do not cause the pad perk to fracture, pad is connected with printed wire reliably, effectively guarantee the quality of flat micromachine.

Among the figure: 1 printed wire, 2 pads, 3 coverlays, 4 openings, 5 substrates.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the embodiment that foundation the utility model is provided, details are as follows:
As Fig. 4-shown in Figure 6, a kind of flexible PCB that is used for flat micromachine comprises circuit board substrate 5, which is provided with symmetrical printed wire 1, is respectively applied for the pad 2 and the coverlay 3 that connect motor brush and power supply input lead; It is characterized in that the described coverlay 3 corresponding cores that connect the pad 2 of motor brush and power supply input lead are provided with the opening 4 that appears pad, described opening 4 edges or coverlay 3 edges cover in pad 2 peripheral parts respectively.Coverlay 3 can be effectively with location, pad 2 edges, thereby avoid pad 2 its adjoining edge in the welding circuit operating process perk, fracture.
And Fig. 1-existing flexible circuit plate structure shown in Figure 3, coverlay 3 forms obvious limit with pad 2, and coverlay 3 can not hide pad 2 edges the location; When welding circuit is operated, very easily cause its connecting portion perk, fracture, influence the electrical property of flexible PCB.
Above-mentioned detailed description of this flexible PCB that is used for flat micromachine being carried out with reference to embodiment; be illustrative rather than determinate; therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection range of the present utility model.
