Abstract
The utility model discloses a flexible circuit board for a laser head light-emitting diode (LED), which comprises a circuit board for installing the LED, a plurality of mounting holes arranged on the circuit board; soldering pads are distributed along the outer edges of the mounting holes and are respectively connected with interface terminals through copper foils; and a reinforcement plate is added on the backside of the circuit board. The flexible circuit board for laser head LED is convenient to solder and can prevent disconnection, insufficient solder and short circuit.
Description
Technical field
The utility model relates to circuit board, specifically is meant the effective flexible circuit board of a kind of laser head light-emitting diodes.
Background technology
The light-emitting diode that common DVD laser head uses has two kinds of CAN TYPE and FRAME TYPE usually, and light-emitting diode is connected with other circuit by single face flexible circuit board FPC-LD usually.The design of single face flexible circuit board FPC-LD structure and pad directly has influence on upright property of light-emitting diode group and solderability.The design of existing single face flexible circuit board FPC-LD is perfect inadequately, occur phenomenons such as broken string, rosin joint or short circuit easily, and its scolding tin activity duration is long.
The utility model content
The problem that the utility model need solve provide a kind ofly make things convenient for scolding tin, prevent to break, the effective flexible circuit board of laser head light-emitting diodes that rosin joint and short circuit take place.
To achieve these goals, the utility model is designed the effective flexible circuit board of a kind of laser head light-emitting diodes, comprise the circuit board that light-emitting diode is installed, be arranged on several installing holes on the circuit board, on the outer of each installing hole, be distributed with pad, each pad is connected with Interface Terminal by the Copper Foil line respectively, increases one deck stiffening plate at the back side of circuit board.
The thickness of described stiffening plate is 0.2mm.
As improvement of the present utility model: described pad is fan-shaped pad or circular ring type pad or oval pad.
Further improve as the utility model: described one deck coverlay that between pad, is provided with.
Further improve as the utility model: the coverlay between the described pad is provided with welding resistance printing ink.
Be provided with welding resistance printing ink between the described Interface Terminal.
The effective flexible circuit board of the utility model laser head light-emitting diodes makes flexible circuit board be not easy distortion, easily assembling and scolding tin by having increased stiffening plate; By the change of bond pad shapes, reasonably cabling avoids occurring broken string and rosin joint; By the increase coverlay between pad, coverlay is provided with and is provided with welding resistance printing ink between welding resistance printing ink and the Interface Terminal, effectively avoids the generation of short circuit.

Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As Fig. 1, Fig. 3, shown in Figure 6, first embodiment of the effective flexible circuit board of a kind of laser head light-emitting diodes.It comprises the circuit board 1 that light-emitting diode is installed, be arranged on four installing holes 3 on the circuit board 1, described installing hole 3 is prismatic and distributes, on the outer of each installing hole 3, be distributed with fan-shaped pad 4, each fan-shaped pad 4 is connected with Interface Terminal 6 by Copper Foil line 5 respectively, increases one deck stiffening plate 2 at the back side of circuit board 1.The thickness of described stiffening plate 2 is 0.2mm, uses resistant to elevated temperatures FR4 or other material.After having increased stiffening plate, the effective flexible circuit board of laser head light-emitting diodes is not easy distortion, easily assembling and scolding tin.After having increased stiffening plate, increased thickness and the intensity of FPC simultaneously.Shown in figure one, stiffening plate carries out extension at installing hole 3 places, makes near the thickness the installing hole 3 thinner, easily pore-forming.Fan-shaped pad 4 is to be used for the light-emitting diode that welds types is CAN TYPE, fan-shaped pad 4 corresponding artificial solder operations, and this fan-shaped pad 4 neither reduces the operation of scolding tin, has also guaranteed the quality of scolding tin.
Described one deck coverlay (not shown) that between fan-shaped pad 4, is provided with.Coverlay between the described pad 4 is provided with welding resistance printing ink 7.Be provided with the assurance of welding resistance printing ink scolding tin operation between the Interface Terminal.Because the distance between the pad is smaller, during the scolding tin operation, solder or tin cream are sticked together easily.Increase one deck coverlay on the Copper Foil, this coverlay also exists between pad, has printed a kind of welding resistance printing ink simultaneously on coverlay.By above coverlay and welding resistance printing ink, during scolding tin, operation is better.
As Fig. 4, shown in Figure 7, be second embodiment of the effective flexible circuit board of the utility model laser head light-emitting diodes, different with embodiment one is that pad 4 is the annular pad.The corresponding tin cream automation of annular pad scolding tin.
As Fig. 2, Fig. 5, shown in Figure 8, be the 3rd embodiment of the effective flexible circuit board of the utility model laser head light-emitting diodes, different with embodiment is that installing hole 3 hard upright row are provided with, pad 4 is oval pad.Oval pad corresponding types is the light-emitting diode of FRAME TYPE LD.
Foregoing is preferred embodiment of the present utility model only, is not to be used to limit embodiment of the present utility model, and those skilled in the art are according to design of the present utility model, and appropriate adaptation of having done or modification all should be within protection ranges of the present utility model.
