Abstract
The utility model relates to a kind of soft printed circuit board automatic aligning target, cross copper face is formed for etching on soft printed circuit board, soft printed circuit board automatic aligning target is cross, it comprises the branch that four inner ends are connected, in each branch, by its inner end to its outer end, its width increases gradually.Each branch is all in trapezoidal.The utility model is for etching shaping cross copper face, and each component even width of the cross copper face formed, has less difference with ideal form.
Description
Technical field
The utility model relates to a kind of target in soft printed circuit board survey production process needed for etching formation cross copper face.
Background technology
In soft printed circuit board production process, usually need to form criss-cross copper face thereon by the method for etching, as shown in Figure 1, this cross copper face is made up of four identical components, and the width a of each branch is identical.In prior art, usual employing target etching is as shown in Figure 2 formed, this target is also in the cross be made up of four branches, one end of each branch is connected to form criss-cross core, be referred to as inner end, the other end is then radial to stretch out, and the part of this extension is rectangular, its direction perpendicular to its bearing of trend is referred to as the width of branch, and the width of each branch is all identical and slightly larger than the width of each component in the cross copper face that will be formed.But, the defect that this target exists when etching is, during etching, liquid medicine ecto-entad attacks target, as shown in arrow in accompanying drawing 3, make the final cross copper face formed as shown in Figure 4, the width of Mei Tiao branch reduces from inside to outside gradually, exists different, thus cause product defects from the ideal form shown in accompanying drawing 1.
Summary of the invention
The purpose of this utility model be to provide a kind of can the automatic aligning target of cross copper face of shaping ideal form.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of soft printed circuit board automatic aligning target, cross copper face is formed for etching on soft printed circuit board, described soft printed circuit board automatic aligning target is cross, it comprises the branch that four inner ends are connected, in each described branch, by its inner end to its outer end, its width increases gradually.
Each described branch is all in trapezoidal.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model is for etching shaping cross copper face, and each component even width of the cross copper face formed, has less difference with ideal form.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of desirable cross copper face.
Accompanying drawing 2 is the schematic diagram of existing target.
Accompanying drawing 3 is for adopting existing target etching schematic diagram.
Accompanying drawing 4 is the schematic diagram of the cross copper face adopting existing target etching to be formed.
Accompanying drawing 5 is the schematic diagram of automatic aligning target of the present utility model.
Accompanying drawing 6 is the schematic diagram of the cross copper face adopting automatic aligning target of the present utility model etching to be formed.
In above accompanying drawing: 1, cross copper face; 2, target.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is further described.
Embodiment one: as shown in Figure 5, a kind of soft printed circuit board automatic aligning target 2 for etching formation cross copper face 1 on soft printed circuit board, it is cross, it comprises the branch that four inner ends are connected, the inner end that these four branches are connected forms the center of cross, and its outer end radially stretches out, and its bearing of trend is called its length direction, and be referred to as Width perpendicular to the direction of its length direction, a direction namely represented in accompanying drawing 5.Each branch of this automatic aligning target 2, by its inner end to its outer end, its width increases gradually, and the speed increased is identical.Most preferred scheme is, each branch is all in trapezoidal, base shorter in trapezoidal is near center, base longer in trapezoidal then becomes outer end, namely on the basis of former rectangle branch, its both sides all increase a right-angled triangle part, and the size of the gable increased can design according to actual needs.The width minimum of the branch of this automatic aligning target 2 is slightly larger than the width of the cross copper face 1 that will be formed.Such as, the inner end width of the branch of this automatic aligning target 2 is 0.1mm, and the width of its outer end then increases 0.02mm in every side.Like this, after etching, the cross copper face 1 formed has identical and four of even width components, as shown in Figure 6.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
Claims (2)
