Abstract

The utility model relates to a circuit compensation FPC, including the FPC plate body, the circuit in the 0.6mm broadband on the FPC plate body includes independent line and unilateral independent line, independent line carries out the compensation of whole circuit, and unilateral independent line carries out the compensation of unilateral circuit. The utility model discloses a circuit compensation FPC carries out the circuit compensation respectively through and/or irregularly distributed's inhomogeneous to the part independent line and unilateral independence, offsets in the etch process independent line and unilateral independence and is corroded the influence of back broadband, guarantees more easily that whole circuit reaches the designing requirement, and the product yield is high, and simple structure is with low costs, extensive applicability.

Description

Line build-out fpc

Technical field

This utility model is related to wiring board, the fpc of more particularly to two-sided and multilamellar.

Background technology

Fpc plate is widely used in various electronic circuit industry.In applying in the industry of the electronic apparatus such as computer main board, because of it Complicated electric property feature determines to need dual platen and the multi-layer sheet of pcb and fpc in a large number.Need in dual platen and multi-layer sheet production To meet the electric property of corresponding line plate by figure transfer producing process, Line broadband be required relatively tight, prior art Dual platen and multiple-plate Line broadband require as 0.06mm+/- 0.02mm, and the circuit in production process has the inequality of local Even and/or irregular distribution, in circuit etching, causes this partly uneven and/or the more quilt of circuit that is being randomly distributed Erode, finally obtain broadband and be more difficult to reach required design width requirement.

Utility model content

Based on this, for prior art, technical problem to be solved of the present utility model be exactly provide a kind of low cost, Simple and effective line build-out fpc.

The technical solution of the utility model is:

A kind of line build-out fpc, including fpc plate body (1), the circuit in the 0.6mm broadband on described fpc plate body (1) includes Independent lines (2) and monolateral independent lines (3), described independent lines (2) carry out overall line build-out, and monolateral independent lines (3) carry out monolateral Line build-out.

Wherein in an embodiment, described overall circuit compensating wide band is 0.3mm, each to described independent lines (2) Monolateral carry out 0.15mm line build-out.

Wherein in an embodiment, described monolateral line build-out broadband is 0.15mm, to described monolateral independent lines (3) One monolateral carries out 0.15mm line build-out.

Wherein in an embodiment, described independent lines (2) broadband after compensation is 0.9mm, described monolateral after compensation Independent lines (3) broadband is 0.75mm.

Hinge structure, line build-out fpc of the present utility model, by uneven and/or be randomly distributed to local Independent lines and monolateral independence carry out line build-out respectively, offset after independent lines and monolateral independence in etch process are corroded Broadband impact is it is easier to ensure that overall circuit reaches design requirement, product yield is high, and structure is simple, low cost, and the suitability is wide.

Brief description

Fig. 1 is the structural representation of line build-out fpc of the present utility model.

In figure, 1--fpc plate body；2-- independent lines；The monolateral independent lines of 3--.

Specific embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments to this utility model it is described in detail.It should be noted that not rushing In the case of prominent, the feature in following embodiment and embodiment can be mutually combined.

Fig. 1 gives the structural representation of the line build-out fpc of this utility model patent, as seen from the figure, this line build-out Fpc, including fpc plate body 1, is dispersed with, in fpc plate body 1, the circuit that design needs, and exists locally uneven and/or do not advise in circuit The independent lines 2 being then distributed and monolateral independent lines 3.Independent lines 2 refer to completely self-contained circuit, and its circuit both sides is all relatively substantially empty In vain, surrounding does not have in-plant All other routes.Monolateral independent lines 3 refer to relatively substantially blank on one side.Locally uneven and/or The independent lines 2 being randomly distributed and monolateral independent lines 3, easily more in the etch process be corroded, cause Line broadband Do not reach design requirement it is therefore desirable to compensate.Independent lines 2 carry out overall line build-out, and overall circuit compensating wide band is 0.3mm, carries out 0.15mm line build-out to each monolateral of independent lines, and the main broadband of the independent lines 2 after compensation is 0.9mm.Single Side independent lines 3 carry out monolateral line build-out, monolateral to the one of monolateral independent lines 3 carry out 0.15mm line build-out, the list after compensation Side independent lines 3 main broadband is 0.75mm.So compensate, the product entirety Line broadband finally obtaining is easier to reach design to be wanted Ask, 0.06mm+/- 0.02mm.

From shell above, line build-out fpc of the present utility model, by local uneven and/or be randomly distributed Independent lines and monolateral independence carry out line build-out respectively, offset wide after independent lines and monolateral independence in etch process are corroded Band impact is it is easier to ensure that overall circuit reaches design requirement, product yield is high, and structure is simple, low cost, and the suitability is wide.

Embodiment described above only have expressed several embodiments of the present utility model, and its description is more concrete and detailed, But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that it is common for this area For technical staff, without departing from the concept of the premise utility, some deformation can also be made and improve, these all belong to In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
