Abstract

The utility model discloses a printed circuit compound board which comprises a soft board, two first insulating layers, at least one first conductive layer and a second insulating layer, wherein the overlapped two first insulating layers are respectively arranged on both faces on one side of the soft board; the overlapped first conductive layers are arranged on one face of the first insulating layer; the second insulating layer is arranged between the two first conductive layers. Therefore, the utility model in a soft and hard compound board mode can be applied to the field of TFT-LCD to replace the welding mode used between TFT-LCD soft and hard boards and the connecting mode used among ACF, a connector and HOT-BAR currently, and thus has the effect of easy assembly and connection.

Description

A kind of printed circuit composite plate

Technical field:

The utility model relates to a kind of printed circuit composite plate.

Background technology:

The TFT-LCD that generally is used for mobile computer or desktop PC, the accompanying transparent indium tin oxide target of its face glass (Indium Tin Oxide; ITO) circuit, desire directly to carry out electrical interconnects with custom circuit plate (as the soft board class of TCP) or some assembly, general common connected mode as shown in Figure 1, it is to utilize its contact 61 with welding manner (or ACF on a circuit board 6, HOT-BAR, connector etc.) be connected with the conductor 71 of soft board 7, but because the contact 61 of this circuit board 6 is all less with the volume of the conductor 71 of soft board 7, and the two must accurate correspondence weld, therefore when contact 61 and conductor 71 both to the seasonable accurately location that is difficult for fast, cause the difficulty when making higher, and the time that is spent and cost are all more; Therefore, with present connected mode and required can't realistic utilization the time.

The utility model content:

Technical problem to be solved in the utility model is: at the deficiencies in the prior art, provide a kind of TFT-LCD of can be used for, be easy to assemble the printed circuit composite plate that connects effect and reach.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of printed circuit composite plate, it comprises: a soft board, first insulating barrier, at least more than one first conductive layer, second insulating barrier, this first insulating barrier is laminated in respectively on two of soft board one side, each first conductive layer is laminated in respectively on the one side of each first insulating barrier, and this second insulating barrier is arranged between two first conductive layers.

Described soft board further includes a base material, is laminated with one second conductive layer on the one side of this base material, is laminated with a protective layer on the one side of this second conductive layer, and described first insulating barrier is stacked at respectively on the another side of protective layer and base material.Described protective layer has one makes described second conductive layer can supply the notch part that contacts with external equipment.Described second conductive layer is a copper material.The conducting of described composite plate is to hole and to cooperate copper facing or elargol metallization for it.

Compared with prior art, the utility model has the advantages that: mode that can soft-hard composite board is applied in the TFT-LCD field, replacing the connection practice of welding, ACF, connector and HOT-BAR between present TFT-LCD rigid-flex, and reach the effect that is easy to assemble connection.
