Description
Technical field
This novel protection structure that relates to a kind of flexible print wiring board and element thereof relates in particular to and a kind ofly corresponds to the protection structure that the electronic component placement is attached with support chip at flexible print wiring board.Offer the flexible print wiring board certain rigidity by this support chip, to strengthen the intensity of flexible print wiring board, avoid its distortion, and can improve tack between electronic component and flexible print wiring board, avoid electronic component to come off or impaired, be applicable to the association area that flexible print wiring board is used and made.
Background technology
Flexible print wiring board (FPC) is suitable for miniaturization, light-weighted requirement owing to have light, thin advantage, therefore is widely used in various electronic product instruments, communication equipment, machine tool, and adopts the equipment complete machine control system of Controlled by Microcomputer.
Consult shown in Figure 1ly, flexible print wiring board 10 is overlapped to form by a plurality of films 11, is provided with circuit layer 12 on film 11.According to actual needs, other meeting adhesive light-emitting diode 13 or other electron component and circuit layer 12 electrically conduct on the flexible print wiring board 10, the material of film 11 is based on flexible plastic materials such as polyester, polyimides, its thickness is only had an appointment about 0.1mm, generally be after finishing the program of this adhesive light-emitting diode 13 by the manufacturer that circuit board is manufactured in the upstream, again flexible print wiring board 10 to be transported to downstream processing producer.As shown in the figure, though light-emitting diode 13 can adopt the SMD LED surface-mount device LED (SMD) of volume miniaturization, thickness is about 0.8mm, but compare with film 11, seem that still the material of film 11 is very weak, therefore often occur in packing or the transportation, stick together the situation that the A of place breaks by light-emitting diode 13 because of external force pressure causes film 11.
Consult Fig. 2; Figure 2 shows that the TaiWan, China application number is No. 95205149 a novel patent; its name is called the high strength chip module, and it is to cover a protection glue 22 at chip 21 tops that are arranged on the flexible print wiring board 20, covers a protective material 23 again on this protection glue 22.Protection glue 22 is non-conductive cream (NCP), and protective material 23 is stainless steel or plastic material.Though this novel emphasizing can offer chip 21 duplicate protections by protection glue 22 with protective material 23, yet in fact, after chip 21 tops are provided with protection glue 22, protective material 23, make weight concentrate on the contrary and oppress on the set-point of chip 21.Moreover the thickness that chip 21, protection glue 22, protective material 23 are stacked is extremely thick, widens the contrast with flexible print wiring board 20 thickness more, and in other words, this novel technological means that provides makes flexible print wiring board 20 easier breaking on the contrary.

Defective in view of known technology; this novel main purpose is to propose the protection structure of a kind of flexible print wiring board and element thereof; offer flexible print wiring board by support chip and have certain degree of hardness; to strengthen the intensity of flexible print wiring board; avoid its distortion; and can improve tack between electronic component and flexible print wiring board, avoid electronic component to come off or impaired.
For achieving the above object, the protection structure of this a kind of flexible print wiring board of novel proposition and element thereof, it comprises:
One flexible print wiring board, it has at least one circuit layer;
At least one electronic component is attached on the one side of flexible print wiring board, and electrically conducts with the circuit of flexible print wiring board;
At least one support chip is arranged on the another side of flexible print wiring board of electronic component placement, and the hardness of this support chip is greater than the hardness of flexible print wiring board, and the Outside Dimensions of support chip is greater than the Outside Dimensions of electronic component.
Preferably, support chip is one of them or its combination of plastics or metal material.
Preferably, electronic component is a surface-mounting LED.
Preferably, flexible print wiring board is arranged on the base plate, and this base plate corresponds to the support chip placement and is provided with through hole.
Preferably, flexible print wiring board is used for a keyboard.
Further understand and approval for this novel structure, purpose and effect is had, existing conjunction with figs. describes in detail.
Description of drawings
Fig. 1 is the structural representation of known flexible print wiring board;
Fig. 2 is that known flexible print wiring board is arranged at the cross-sectional view in the board housing;
Fig. 3 is the structural representation of facing of this novel preferred embodiment;
Fig. 4 is the side-looking structural representation of this novel preferred embodiment;
