The utility model discloses a double -deck copper, lower floor's rupture, the upper strata still can switch on, avoids line release, the tensile reinforce, in addition, adopting double -deck copper, conducting heat, soldering temperature can reduce to 350 DEG C, prevents to cover the membrane bubble, and the temperature is low simultaneously, can be energy -concerving and environment -protective.
Description
Technical field
The utility model relates to a kind of luminous lamp strip, is specifically related to a kind of two-sided rigid-flex luminous lamp strip.
Background technology
LED lamp bar refers to and LED is assembled on banded FPC (FPC) or PCB (rigid wiring board), because its shape of product is gained the name as the strap.Because long service life (normally the life-span was at 8 ~ 100,000 hours), environmental protection and showing up prominently in various decoration industry gradually.
In prior art, the joint of FPC is one deck copper, and after the pad solder of rigid wiring board, when installing and using, frequent bending, is repeatedly easy to fracture failure back and forth afterwards.Meanwhile, owing to being that heating-up temperature is high across cover layer to add thermal weld during welding, welding temperature will reach 420 DEG C, and high temperature easily causes the cover layer bubble of periphery.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind ofly can avoid that circuit disconnects, two-sided rigid-flex luminous lamp strip that resistance to tension is strong.
To achieve these goals, the utility model realizes by the following technical solutions:
The two-sided rigid-flex luminous lamp strip of one of the present utility model, the LED group comprising the FPC being provided with multiple via, rigid wiring board and be arranged on rigid wiring board; FPC comprises sandwich circuit under soft board inner substrate, soft board upper layer circuit and the soft board that is connected with soft board upper layer circuit; The two sides of soft board inner substrate are respectively equipped with upper strata copper coin and lower floor's copper coin, and be coated with layers of copper in via, lower floor's copper coin is connected with rigid wiring board; Upper strata copper coin is connected with soft board upper layer circuit.
Above-mentioned lower floor copper coin and rigid wiring board pass through tin welding.
Under above-mentioned soft board upper layer circuit and soft board, sandwich circuit also lays respectively at the two sides of soft board inner substrate.
Under above-mentioned soft board upper layer circuit and soft board, sandwich circuit is equipped with cover layer.
The utility model adopts double-deck copper coin, and lower floor fractures, and upper strata still can conducting, and avoid circuit to disconnect, stretching resistance is strong; In addition, adopt double-deck copper coin, conduct heat, welding temperature can be reduced to 350 DEG C, and prevent cover layer bubble, simultaneous temperature is low, can energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Each label in figure: sandwich circuit 6, upper strata copper coin 7, lower floor's copper coin 8, cover layer 9, tin soldering area 10 under via 1, rigid wiring board 2, LED group 3, soft board inner substrate 4, soft board upper layer circuit 5, soft board.
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
See Fig. 1, the two-sided rigid-flex luminous lamp strip of one of the present utility model, comprises the FPC, rigid wiring board 2 and the LED group 3 that is arranged on rigid wiring board 2 that are provided with multiple vias 1; FPC comprises sandwich circuit 6 under soft board inner substrate 4, soft board upper layer circuit 5 and the soft board that is connected with soft board upper layer circuit 5; The two sides of soft board inner substrate 4 are respectively equipped with upper strata copper coin 7 and lower floor's copper coin 8, are coated with layers of copper in via 1, and lower floor's copper coin 8 and rigid wiring board 2 are by tin welding (heat fused, cooling forms tin soldering area 10 with regard to welding is upper); Upper strata copper coin 7 is connected with soft board upper layer circuit 5.
In the present embodiment, under soft board upper layer circuit 5 and soft board, sandwich circuit 6 also lays respectively at the two sides of soft board inner substrate 4.Under soft board upper layer circuit 5 and soft board, sandwich circuit 6 is equipped with cover layer 9.
The utility model adopts two-sided hot-pressing technique, upper and lower two-layer copper coin is established at soft board inner substrate 4 place, and via 1 is beaten on soft board inner substrate 4, and copper facing on via 1, after upper and lower conducting and rigid wiring board 2 pad solder, levels copper coin is all burn-on, lower floor fractures, upper strata still can conducting, and avoid circuit to disconnect, pulling force is strong.
The utility model, owing to adopting double-deck copper coin, conducts heat, and welding temperature can be reduced to 350 DEG C, and prevent cover layer 9 bubble, simultaneous temperature is low, can energy-conserving and environment-protective.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
