Abstract
The utility model discloses a keyboard of flexible line way board based on welding has LED, from the top down include keyboard frame, flexible line way board, light guide plate and base plate in proper order, be equipped with a plurality of key caps in the keyboard frame, regional and the non - welding region of welding is drawn together to flexible line way backboard bread, be equipped with convex silver thick liquid welding point on the welding region, the welding has LED on the silver thick liquid welding point, the regional cover of non - welding has circuit tectorial membrane layer, the light guide plate openly is equipped with upper printing ink and bottom printing ink, the silver color of bottom printing ink for being used for the reflection of light, the black of upper strata printing ink for being used for the shading. The utility model discloses a keyboard need not independent backlight unit and LED protection resistance, simple structure.
Description
Technical field
The utility model is related to art of keypads and in particular to a kind of keyboard based on the FPC being welded with led.
Background technology
Keyboard is widely used as the input equipment of man-machine interaction, and existing keyboard is arranged specially in order to light
The backlight module of door, therefore complex structure, and existing backlight module includes anti-dazzling screen, light guide plate, reflector plate and backlight,
Backlight generally adopts led panel, and led panel includes substrate layer, conductive layer and welding LED lamp on the electrically conductive, due to led
Lamp is directly welded on conductive layer, welds on the electrically conductive again, prevent after needing to be connected in series each LED lamp and protective resistance
Led is burned out, complex procedures, and manufacturing cost is high, and disqualification rate is high.
Utility model content
Utility model purpose: the utility model is intended to overcome the defect of prior art, provide a kind of based on the led being welded with
The keyboard of FPC.
Technical scheme: a kind of keyboard based on FPC, include keyboard frame, flexible circuitry from top to bottom successively
Plate, light guide plate and substrate；It is provided with multiple keycaps in described keyboard frame；Described flexible circuitry back includes welding region and non-
Welding region, described welding region is provided with the silver paste pad of protrusion, and silver paste pad is welded with led, described non-
Welding region is coated with circuit coating layer；Described light guide plate front is provided with upper strata ink and bottom ink, and described bottom ink is
For reflective silver color, described upper strata ink is the black for shading.
Further, it is provided with scissor and silica gel push-button below described keycap, described silica gel push-button is pasted onto described flexibility
On wiring board.
Further, described keyboard also includes controller and light-intensity test unit, described light-intensity test unit and described led
All it is connected with controller.
Further, described keyboard also includes timing unit and the vibrations unit shaking, described timing unit can occur
All it is connected with described controller with described vibrations unit.
Further, described keyboard also includes battery and bluetooth module.
Further, described FPC is transparent FPC.
Beneficial effect: FPC of the present utility model, led is directly welded on FPC, need not be independent
Backlight module, and led is welded on FPC by silver paste pad, additionally need not arrange protective resistance, first device
Part is few, and keyboard integral thickness is little.
Brief description
Fig. 1 is the utility model keyboard structure schematic diagram, the structure such as not shown keyboard frame, keycap；
Fig. 2 is the structure between substrate, light guide plate, FPC and keycap；Led on FPC is not shown.
Specific embodiment
Reference: 1 substrate；2 light guide plates；3 FPCs；4led；4.1 silver paste pads；4.2 circuit coating layers；5
Scissor；6 silica gel push-buttons；7 keycaps.
A kind of keyboard based on the FPC being welded with led, including including keyboard frame, flexibility from top to bottom successively
Wiring board 3, light guide plate 2 and substrate 1；It is provided with multiple keycaps 7 in described keyboard frame；Described flexible circuitry back has silver paste
Circuit, described FPC 3 back side includes welding region and non-solder region, and described welding region is provided with protrusion flexible wires
The silver paste pad 4.1 of road plate, silver paste pad 4.1 is welded with led4, and described non-solder region overlay has circuit to cover
Film layer 4.2；Described light guide plate 2 front is provided with upper strata ink and bottom ink, and described bottom ink is for reflective silver color, institute
State the black that upper strata ink is for shading.Described circuit coating layer 4.2 does not have electric conductivity, and described circuit coating layer 4.2 is same
When play cover and insulation effect.It is provided with two described led silver paste pads, described in two in each described welding region
Weld a led between led silver paste pad, between the silver paste circuit of described led and flexible circuitry back, have certain interval.
For example, the thickness of silver paste circuit is 9 μm, a diameter of 0.5mm of described led silver paste pad 4.1, due to the weldering of described led silver paste
Contact 4.1 protrudes silver paste circuit, and the conductive area of led silver paste pad is less, and the resistance of led silver paste pad 4.1 is relatively
Greatly, therefore do not need to arrange protective resistance, directly led is welded on and is prevented from led on led silver paste pad 4.1 yet and is burnt
Bad.It is provided with scissor and silica gel push-button, described silica gel push-button is pasted onto on described FPC below described keycap.Described key
Disk also includes controller and light-intensity test unit, and described light-intensity test unit and described led are all connected with controller, when light intensity inspection
When the measured value surveying unit is less than setting Intensity threshold, controller controls led to open, thus realizing intelligentized control method.Described key
Disk also includes timing unit and the vibrations unit shaking can occur, described timing unit and described vibrations unit all with described control
Device processed is connected, and timing unit can monitor keyboard from opening use time instantly, when deployed between exceed setting time threshold
During value, controller controls vibrations unit vibrations, thus reminding user's use time long it should suitable rest, thus being beneficial to
The health of user.Described keyboard also includes battery and bluetooth module so that keyboard can be wirelessly connected with main frame.Flexible circuitry
Plate is transparent FPC, the light that led sends after the ink reflectance on light guide plate so that keyboard light so that
Keyboard disclosure satisfy that the use at night.
Although the utility model is illustrated with regard to preferred embodiment and described, those skilled in the art should manage
Solution, without departing from claim limited range of the present utility model, the utility model can be carried out various change and
Modification.
