Abstract
The utility model discloses a kind of pad and backlight FPC semi-finished product, pad includes mirror symmetry setting and the A poles part being mutually electrically connected and K poles part, the L-shaped structure in A poles part and K poles part, and the size of A poles part and K poles part is all higher than the size of the leg of LED component；Backlight FPC semi-finished product include FPC plates, LED component and multiple above-mentioned pads, and being set on FPC plates of being arranged in order of multiple pads, LED component is adhered on FPC plates, and the A poles part and K poles part of the positive and negative anodes of the leg of LED component and pad weld together." L " type pad design can improve rosin at pad because being rubbed or rosin falls to visible area so that the phenomenon that backlight leads to the problem of white point white seal due to external force acts in its technical solution, by way of reducing pad, the contact of surface tin cream can be effectively reduced, while meets the thrust test of pad.
Description
Technical field
The utility model is related to backlight FPC product technical fields more particularly to a kind of pad and backlight FPC semi-finished product.
Background technology
What is be usually arranged in order on FPC plates is disposed with more pad, plays the leg that the LED that is electrically connected is played when connecting LED
Effect.Refering to Fig. 1, for the pad structure and application schematic diagram being applied in the prior art on backlight FPC plates, backlight at present
It is LED pads recommended by the manufacturer, the leg 30 of LED20 is welded on the table of square pads 10 generally using square pads 10 in FPC
Face, but easily occur the phenomenon that rosin falls to visible area at pad, so as to generate white point white seal in process of production.
Utility model content
For the above-mentioned problems in the prior art, a kind of rosin for being intended to be effectively improved at because of pad is now provided
Because rubbed or external force act on due to rosin fall to visible area so that backlight leads to the problem of the pad of white point white seal phenomenon
And backlight FPC semi-finished product.
The convenient and solid and reliable fixed structure and communication apparatus for being combined decoration with active key, to overcome
Above-mentioned technological deficiency.
Specific technical solution is as follows：
A kind of pad, applied on backlight FPC plates, pad includes mirror symmetry setting and the A poles part being mutually electrically connected and K poles
Part, the L-shaped structure in A poles part and K poles part, and the size of A poles part and K poles part is all higher than the weldering of LED component
The size of foot.
The utility model additionally provides a kind of backlight FPC semi-finished product, including FPC plates, LED component and multiple above-mentioned welderings
Disk, and being set on FPC plates of being arranged in order of multiple pads, LED component is adhered on FPC plates, and the leg of LED component is just
The A poles part and K poles part of cathode and pad weld together.
Preferably, further include light guide plate, and FPC plates are installed on the lower side of light guide plate along upper.
The advantageous effect of above-mentioned technical proposal is：
" L " type pad design can improve rosin at pad because being rubbed or rosin is fallen to visually due to external force acts on
Area by way of reducing pad, can effectively reduce surface tin so that the phenomenon that backlight leads to the problem of white point white seal
The contact of cream, while meet the thrust test of pad.
Description of the drawings
Fig. 1 is the pad structure and application schematic diagram being applied in the prior art on backlight FPC plates；
Fig. 2 is the utility model welding plate structure schematic；
Fig. 3 is the structure diagram of the utility model backlight FPC semi-finished product.
Specific embodiment
In order to be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, with
Lower embodiment combination attached drawing 2 and Fig. 3 are specifically addressed the pad provided by the utility model applied on backlight FPC plates.
Embodiment one,
Referring to Fig.2, the structure diagram for pad；It is the structure diagram of backlight FPC product semi-finished product with reference to Fig. 3.And
Clearly to show the structure feature of the present embodiment, omitted in figure and part-structure is shown, part-structure is then shown in a manner of perspective.
As shown in Figures 2 and 3, pad provided by the utility model is applied in backlight FPC plate (not shown)s, weldering
Disk 1 includes mirror symmetry and sets and the A poles part being mutually electrically connected and K poles part, the L-shaped structure in A poles part and K poles part,
And the size of A poles part and K poles part is all higher than the size of the leg 3 of LED component 2.
Specifically, as shown in Figure 3, pad 1 is arranged on FPC plates, LED component 2 is connected on FPC plates and between the two
Coated with tin cream, and 3 positive and negative anodes of leg of LED component 2 weld together with the A poles part of pad 1 and K poles part, so as to shape
It is integrally formed.And above-mentioned A poles part and the size of K poles part are all higher than 3 size of leg of LED component 2.Refer to leg 3
Boundary all on the surface of 1 each section of pad, without departing from the boundary of 1 each section of pad.
Based on above-mentioned technical proposal, the design of " L " type pad 1 can improve because the rosin at pad 1 is because being rubbed or external force
Effect and rosin falls to visible area so that the phenomenon that backlight leads to the problem of white point white seal.And the size of pad 1 according to
The specification of corresponding LED component 2 is designed accordingly, and in contrast, existing square pads 1 are when with steel mesh brush tin cream, tin
Cream can attached full weld disk 1, and the position shared by the leg 3 of LED component 2 itself only some, 1 pad 1 of square pads is remaining
Area is opposite " L " types pad 1 it is big, remaining place rosin on surface when being rubbed or external force is easy to fall off.This implementation
In example, by way of reducing pad 1, the contact of surface tin cream can be effectively reduced, while meets the thrust test of pad 1.
Also, designed by original rectangular LED pads 1, occurring falling the bad of rosin at pad 1 in production has 5%, passes through improvement " L " types
Pad 1 can improve rosin obscission, and be designed suitable for the LED pads 1 of all backlight FPC products completely.
Embodiment two,
With reference to shown in Fig. 3, the utility model additionally provides a kind of backlight FPC semi-finished product, (does not show in figure including FPC plates
Go out), LED component 2 and multiple above-mentioned pads 1, and being set on FPC plates of being arranged in order of multiple pads 1, LED component 2 is viscous
It is connected on FPC plates, and 3 positive and negative anodes of leg of LED component 2 weld together with the A poles part of pad 1 and K poles part.Further
, backlight FPC semi-finished product further include light guide plate, and FPC plates are installed on the lower side of light guide plate along upper.
The above is only the preferred embodiment of the present invention, is merely illustrative for the utility model, and
It is unrestricted.Those skilled in the art understands, can be to it in the spirit and scope limited in the utility model claims
Many changes are carried out, are changed or even equivalent, but fall in the scope of protection of the utility model.
