Description
Technical field
The utility model is related to FPC technical fields, more specifically, are related to a kind of FPC welding structures.
Background technology
FPC (Flexible Printed Circuit, flexible circuit board) is using print made of insulating substrate flexible
Brush wiring board has bending degree high, walks the features such as line density is high, thickness is thin, quality is small.It can be appropriate according to application scenarios difference
Design, is widely used in terms of electronic product.
By the binding region being made of the golden yellow conductive contact blade of numerous neat arrangements, these conductive contact blades on FPC plates
The binding region of composition will usually be connected from different printed circuit boards, and since these conductive contact blades are usually than relatively thin, use
Service life is relatively short, therefore, damage is very easy in production test procedure, once these conductive contact blades damage, whole FPC is just
It scraps, thereby results in the raising of production cost.
Currently, when two FPC are welded, typically the edge-perpendicular of a FPC extends a part of conduct wherein
(welding) region is bound, binding region is provided with pad, each conductive contact blade is longitudinally extended on pad, multiple conductive tactile
It is laterally distributed between piece, wherein the part at adjacent pads edge is covering diaphragm area, in this way, conductive contact blade is having the area of coverage
Domain and without covering diaphragm area intersection frangibility, especially in each conductive contact blade cross direction profiles, due to cross direction profiles
Area it is smaller, and the conductive contact blade of cross direction profiles is easy to be stressed it is caused to fracture, therefore so that between two FPC
Weld easy fracture.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of FPC welding structures, so that the welding between FPC
Problem not easy to break.
FPC welding structures provided by the utility model, including substrate and copper foil, copper foil is covered in the surface of substrate, in copper
The position far from copper foil edge is provided with pad on foil；Wherein, multiple conductive contact blades, each conduction are arranged at intervals on pad
Contact is obliquely extended on the longitudinal direction of pad, between each conductive contact blade in the transverse direction of pad arranged askew.
Furthermore it is preferred that structure be：The via of through substrate and copper foil is equipped on each conductive contact blade.
Furthermore it is preferred that structure be：Via stagger setting on adjacent conductive contact.
Furthermore it is preferred that structure be：Conductive contact blade is located at the width that the width at via is more than conductive contact blade rest part.
Furthermore it is preferred that structure be：The surface that conductive contact blade is not arranged in pad is provided with solder mask.
Furthermore it is preferred that structure be：The surface of conductive contact blade is provided with Kapton.
It is multiple conductive tactile by being spaced setting on FPC pads using above-mentioned FPC welding structures according to the present utility model
Piece, each conductive contact blade are obliquely extended on the longitudinal direction of pad, between each conductive contact blade in the transverse direction of pad arranged askew,
To reduce stress suffered by FPC, the risk of weld easy fracture is reduced.
Description of the drawings
By reference to the description below in conjunction with attached drawing, and with the utility model is more fully understood, this reality
It will be more clearly understood and understood with novel other purposes and result.In the accompanying drawings：
Fig. 1 is the welded positive structure diagrams of FPC according to the utility model embodiment；
Fig. 2 is the FPC welding structure schematic diagrames according to the utility model embodiment.
Identical label indicates similar or corresponding feature or function in all the appended drawings.
In figure：Substrate 110, copper foil 120, pad 210, conductive contact blade 211.
Specific implementation mode
Specific embodiment of the utility model is described in detail below with reference to attached drawing.
It is stressed the problem of being easy that weld is caused to be broken between aforementioned existing FPC, the utility model passes through
Multiple conductive contact blades are arranged in interval on FPC pads, and each conductive contact blade is obliquely extended on the longitudinal direction of pad, each conductive tactile
Arranged askew reduces the risk of weld easy fracture to reduce stress suffered by FPC in the transverse direction of pad between piece.
To illustrate that FPC welding structures provided by the utility model, Fig. 1 show the FPC according to the utility model embodiment
Welded facing structure, Fig. 2 shows the FPC welding structures according to the utility model embodiment.
As shown in Figure 1, FPC welding structures provided by the utility model include substrate 110 and copper foil 120, it is remote on copper foil 120
Position from copper foil edge is provided with pad 210；Wherein, multiple conductive contact blades 211 are arranged at intervals on pad 210, it is each
Conductive contact blade is obliquely extended on the longitudinal direction of pad 210, between each conductive contact blade in the transverse direction of pad 210 arranged askew.
It is adequately electrically connected with soldered circuit board when wherein, in order to make conductive contact blade weld, each conductive tactile
On piece is equipped with the via (not shown) of through substrate and copper foil, the via stagger setting on adjacent conductive contact.In this way,
Then it is possible to prevente effectively from tin cream links together on conductive contact blade surface.
In addition, conductive contact blade is located at the width that the width at via is more than conductive contact blade rest part.In this way, being located at via
The conductive contact blade at place widens the intensity increased at conductive contact blade lines via, avoids because conductive contact blade edge fractures at via
And it influences to be welded and fixed.
Further, to avoid the operation error of operating personnel, cause the region for being welded to non-conductive contact, pad not
The surface that conductive contact blade is arranged is provided with solder mask, in this way, then it is possible to prevente effectively from being welded to non-conductive contact region.
In addition, to prevent conductive contact blade from being aoxidized, the surface of conductive contact blade is provided with Kapton, in this way, then
Conductive contact blade can be avoided to be aoxidized.
FPC welding structures according to the present utility model are described in an illustrative manner above with reference to attached drawing.But this field skill
Art personnel should be appreciated that the FPC welding structures proposed for above-mentioned the utility model, can also not depart from the utility model
Various improvement are made on the basis of content.Therefore, the scope of protection of the utility model should be by appended claims
Hold and determines.
