Description
Technical field
The present invention relates to a kind of luminous lamp strip, be 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.
Summary of the invention
For the deficiency that prior art exists, the object of the invention 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 present invention realizes by the following technical solutions:
The two-sided rigid-flex luminous lamp strip of one of the present invention, 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 present invention 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.
