Abstract
The utility model discloses a kind of compartmented high alignment golden finger wiring board of flexible high density, it is characterised in that：Including FPC body and golden finger, on the golden finger pressing assist side body, the golden finger includes B sections, C sections and D sections, described B sections and C sections, groove is provided between C sections and D sections, described B sections equal with the distance that D sections of tops are higher by bottom portion of groove, and the distance of C sections of top eminence bottom portion of groove is more than the distance that B sections of tops are higher by bottom portion of groove.The utility model reasonable in design, is divided into three sections by the golden finger of whole segmentation, and interlude is higher by the height of both sides, so that the contraposition offset accuracy of every section of golden finger is less than 1/9 golden finger width, so that product contact resistance is smaller, signal transmits more smooth, better reliability.
Description
Technical field
The utility model is related to electronic circuit technology field, and in particular to a kind of compartmented high golden hand of alignment of flexible high density
Refer to wiring board.
Background technology
Wiring board is to realize Electronic products manufacturing or the important component of making, if two pieces of wiring boards interlinked
Volume, i.e., physically connect on circuit by two pieces of wiring boards, then generally require the edge connector used and be commonly called as " golden finger "
(edge connector).Many exposed copper packings are contained on golden finger, in use, wherein a piece of golden finger is injected another
On a piece of suitable slot of wiring board.
The golden finger of existing FPC is overall section, when being processed on FPC to golden finger
When, the harmomegathus of the size of FPC is big, and the change in size of harmomegathus is the summation of following two kinds changes, and one is soft after etching
Property board substrate harmomegathus caused by change in size, two be product golden finger with screen body golden finger hot pressing when cause second
Material heat expansion；Occur when easily causing product golden finger and the golden finger contraposition of screen body due to the change of flexible circuitry board size inclined
Move, current industry can accomplish product golden finger and shield golden finger width of the body golden finger contraposition skew less than 1/3, and golden finger
The size and basic resistance for aligning skew have close relationship, and offset is smaller, and contact resistance between the two is smaller so that production
The signal transmission of product is more smooth.
Accordingly, it would be desirable to the problem of a kind of high alignment golden finger wiring board is to solve current golden finger aligning accuracy.
Utility model content
Utility model purpose：For it is above-mentioned it is of the prior art exist the problem of and deficiency, the purpose of this utility model is
There is provided a kind of flexible high density compartmented high alignment golden finger wiring board.
Technical scheme：To reach above-mentioned purpose, a kind of compartmented high alignment gold of flexible high density described in the utility model
On finger wiring board, including FPC body and golden finger, the golden finger pressing assist side body, the golden finger
Including B sections, C sections and D sections, described B sections and C sections, groove is provided between C sections and D sections, described B sections and D sections of tops are higher by groove-bottom
The distance in portion is equal, and the distance of C sections of top eminence bottom portion of groove is more than the distance that B sections of tops are higher by bottom portion of groove.
Further, described B sections, quantity more than B section gold of the C section golden finger inconsistent with the quantity of D sections of golden fingers
The quantity of finger.The quantity of B sections and D section golden fingers is inconsistent, and holding left and right is asymmetric, and C sections of interlude is higher by B sections and D sections,
It is easy to golden finger to be matched with another circuit screen body, positional accuracy is high.
Further, the golden finger is provided with release liners with FPC body joining place, and the release liners are provided with
Tear hand.Release liners can prevent debris from producing good antifouling and protective effect to golden finger.
Further, the corner at described B sections, C sections and D sections of two ends is with arc transition.By corner with circular arc mistake
Cross, it is to avoid torn when golden finger is assembled, occur situations such as damaged.
Further, the FPC body centre position is provided with reinforcing chip.
Above-mentioned technical proposal can be seen that the beneficial effects of the utility model：
（1）The compartmented high alignment golden finger wiring board of a kind of flexible high density described in the utility model, by existing golden hand
The overall alignment of finger is divided into after three sections, and interlude is more than the height of both sides, is easy to match golden finger with another circuit screen body,
Accurate positioning.
（2）The compartmented high alignment golden finger wiring board of a kind of flexible high density described in the utility model, the entirety of golden finger
Arrangement is divided into three sections, is averagely reduced to every section of golden finger harmomegathus is relative, is changed into the most left PIN of former whole segmentation golden finger to most right
The 1/3 of PIN size harmomegathus change so that the contraposition offset accuracy of every section of golden finger is less than 1/9 golden finger width so that
Product contact resistance is smaller, and signal transmits more smooth, better reliability.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1- FPCs body, 2- golden fingers, 21-B sections, 22-C sections, 23-D sections, 3- grooves.
