Abstract
The utility model discloses an LED lamp string, which comprises at least one LED unit and a flexible printed circuit board for assembling the LED unit, wherein the body of the flexible printed circuit board is just a metal layer; and a circuit is etched on the metal layer to form a metal circuit layer. The LED lamp string does not cause occurrence about removal and delamination of the base material of the traditional double-face circuit board. A copper foil is drilled after being cut; and the drilled holes are wire connecting holes; since the copper foil has no insulating base layer in the middle and the copper coil is through and has good conductivity, no through holes are drilled; therefore, the cost for drilling through holes is saved; simultaneously copper sedimentation and copper plating treatment are not needed; the usage amount of chemical medicines are reduced; harm to human bodies and the environment is reduced; and the problem about quality caused by bad copper sedimentation and plating does not exist.
Description
Technical field
The utility model relates to the LED application, and being specially and adopting main body is the LED lamp band of the flexible printed circuit board of a metal level.
Background technology
LED lamp band is made extensive use flexible printed circuit board (FPC).Traditional handicraft adopts non-metallic film as insulator, and the two-sided then metal forming that adheres to forms the two-sided flexible printed circuit substrate that covers metal, adopts traditional circuit board process to make again.Copper Foil and middle insulation displacement lamination can appear in this sheet material when subsequent installation LED lamp band, cause scrapping of whole piece LED lamp.Base material will bore the wiring hole at via and two after opening material.Bored and will pass through heavy copper and copper facing behind the hole, its objective is that the method through chemical reaction and electrolysis plates layer of copper on the insulation colloid in the hole, making can mutual conduction between the copper on two sides.Heavy copper and copper facing operation have been used a series of chemicals such as a large amount of strong acid, highly basic, operational hazards during use, and the gas of liquid medicine volatilization has very big harm to human body; It is difficult that used useless liquid medicine is handled; Pollution to environment is big, when producing, can occur heavy copper facing bad phenomenon simultaneously, not heavy plated with copper in the hole; Making between two metal coverings can not mutual conduction, causes scrapping of led board.
The utility model content
The purpose of the utility model is to provide a kind of and adopts single metal level to substitute traditional two-sided LED lamp band that covers the flexible printed circuit substrate structure of metal, need not through heavy copper and copper facing operation, environment-friendly high-efficiency in the circuit board processing.
For realizing above-mentioned purpose; The method that the utility model adopts is: a kind of LED lamp band; Comprise the flexible printed circuit board of at least one LED unit and assembling LED unit, the main body of flexible printed circuit board is merely a metal level, and circuit etching forms the metallic circuit layer on metal level.
Further, metal level is Copper Foil, aluminium foil, silver foil, zinc paper tinsel or alloying metal paper tinsel.
Further, the upper surface of metal level and lower surface are pasted with the insulating cement body respectively and form three-decker, and the insulation colloid is formed by adhesive or thermosetting flexible glue mucous membrane.
The LED lamp band that adopts the utility model to make traditional double upper thread road plate substrate can not occur and peel off the phenomenon of layering.Copper Foil is boring after opening material, and the hole of brill at this moment is a wiring hole, because there is not insulated substrate in the middle of the Copper Foil; Copper Foil itself is exactly conducting, and electric conductivity is good, need not bore via; Save to bore the expense of via, simultaneously because there is not via, so just need not sink copper and copper plating treatment; Reduce the use amount of chemicals, reduce harm, and can not have the heavy bad quality problem that occurs of copper facing human body and environment.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Be illustrated in figure 1 as the two-sided flexible printed circuit substrate that covers metal of tradition, two sides metal level 3 folder adheres on the insulation colloid 4, must manage to let two sides metal level conducting when producing circuit board, must bore via.General arts demand bores via and through heavy copper, copper facing operation, plated with copper forms the conducting that copper plate 5 could be realized lower metal layer in via.
Fig. 2, shown in Figure 3 be a kind of LED lamp band, comprise the flexible printed circuit board 2 of at least one LED unit 1 and assembling LED unit, the main body of flexible printed circuit board 2 is merely a metal level 3, circuit etching forms the metallic circuit layer on metal level 3.Metal level 3 can be Copper Foil, aluminium foil, silver foil, zinc paper tinsel or other alloying metal paper tinsels as required, and what adopt in the embodiment is Copper Foil.The upper surface of metal level 3 and lower surface are pasted with insulation colloid 4 respectively and form three-decker, and the insulation colloid is adhesive or thermosetting flexible glue mucous membrane.
The utility model traditional double upper thread road plate substrate can not occur and peel off the phenomenon of layering.Copper Foil is boring after opening material, and the hole of at this moment boring is a wiring hole, because there is not insulated substrate in the middle of the Copper Foil; Copper Foil itself is exactly conducting, and electric conductivity is good, need not bore via; Save to bore the expense of via,, need not sink copper and copper plating treatment simultaneously because there is not via; Reduce the use amount of chemicals, reduce harm, and can not have the heavy bad quality problem that occurs of copper facing human body and environment.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
