Description
Technical field
The utility model is related to a kind of PFC plates, the golden finger structure on specifically a kind of PFC.
Background technology
Flexible printed circuit board FPC (Flexible Printed Circuit Board) is with flexible insulating substrate
Manufactured printed circuit has the advantages that many rigid printed circuit boards do not have.Such as it can be with free bend, winding, folding
It is folded, arbitrary arrangement can be required according to space layout, and arbitrarily move and flexible in three dimensions, so as to reach components and parts assembling and
The integration of conducting wire connection.The volume of electronic product can be substantially reduced using FPC, is applicable in electronic product to high density, small-sized
Change, the needs that highly reliable direction is developed.Therefore, FPC space flight, military affairs, mobile communication, laptop computer, computer peripheral equipment,
It is widely used on the fields such as PDA, digital camera or product.
FPC is equipped with golden finger, for connecting other component.The width of golden finger on current FPC is smaller, works as FPC
When being connect with LCD, the equivalent width of the golden finger on the width and LCD of the golden finger on the FPC, the requirement of golden finger formed precision
Height, the anti-hot shortness's performance requirement of material is high, and low production efficiency, production yield is low, and production cost is high.
Invention content
The technical problem to be solved by the present invention is to provide the golden finger structures on a kind of FPC, increase connecing for golden finger
Region is touched, connects relatively reliable stabilization, it is ensured that welding quality reduces production cost.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of golden finger structure on FPC, including plate body and the golden finger being arranged on the plate body, the golden finger includes
Several golden finger pieces arranged in parallel, the width of golden finger piece end are less than the width in the middle part of golden finger piece, and the gold hand
Refer on piece to be equipped with to weld the circular vias that tin is electrically connected plate body and printed circuit board, golden finger piece on the plate body
Width is bigger than the width of the golden finger piece on the LCD that is connect with the plate body, and golden finger on piece is additionally provided with cross section in polygon
Through-hole, the through-hole are located at the medium position of golden finger piece.
The cross section of the through-hole is rectangle.
The ratio of the width of the golden finger piece end and the width at middle part is 3：5.
The width of golden finger piece is bigger 1-2mm than the width of the golden finger piece on the LCD that is connect with the plate body on the plate body.
The width of the through-hole is the 1/3 of golden finger on piece maximum width.
The via of the adjacent golden finger on piece shifts to install.
The utility model increases the contact area of golden finger, connects relatively reliable stabilization.By setting via, weldering ensure that
Quality is connect, reduces production cost.In addition, by setting through-hole so that the tin cream that heat pressure adhesive overflows when welding can flow into this
Through-hole avoids it from overflowing outside FPC golden fingers piece and lead to short circuit, ensure that welding quality, and it is also big to produce and process difficulty
Width declines, while also reduces maintenance and repair cost.
Description of the drawings
Attached drawing 1 is the utility model schematic front view.
Specific embodiment
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific embodiment with reference to attached drawing.
As shown in Figure 1, the utility model discloses the golden finger structure on a kind of FPC, including plate body 1 and is arranged on this
Golden finger on plate body 1, the golden finger include several golden finger pieces 2 arranged in parallel, the width of 2 end 5 of golden finger piece
Less than the width in the middle part of golden finger piece, and the golden finger piece 2 is equipped with made plate body and printed circuit board electricity for welding tin
Property connection circular vias 4, the width of golden finger piece is than the width of the golden finger piece on the LCD that is connect with the plate body on the plate body
Greatly, the through-hole 3 that cross section is in polygon is additionally provided on golden finger piece 2, which is located at the medium position of golden finger piece.By adding
The width of wide golden finger piece increases contact area, improves connection stability and reliability.FPC plates are easily facilitated using via
With the welding of LCD or other circuit boards, the reliability and stability of welding are promoted.
The cross section of the through-hole is rectangle.Through-hole among golden finger piece so that heat pressure adhesive overflows when welding
Tin cream can flow into the through-hole, it is avoided to overflow FPC golden fingers pieces outer and lead to short circuit, ensure that welding quality, and
Production and processing difficulty also declines to a great extent, while also reduce maintenance and repair cost.
The ratio of the width of the golden finger piece end and the width at middle part is 3：5, realize the contact area of bigger.
The width of golden finger piece is bigger 1-2mm than the width of the golden finger piece on the LCD that is connect with the plate body on the plate body.
The width of the through-hole is the 1/3 of golden finger on piece maximum width, it is made both to have can guarantee that certain welding was strong in this way
Degree, but can there are enough spaces overflow scolding tin.
The via of the adjacent golden finger on piece shifts to install.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement is carried out to which part technical characteristic,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
