Background technology
The title of circuit board has: wiring board, pcb board, aluminium base, high frequency plate, thick copper coin, impedance plate, PCB, ultra-thin wiring board, ultrathin circuit board, printing (copper lithographic technique) circuit board etc.Circuit board makes circuit miniaturization, visualize, for permanent circuit batch production and optimize electrical appliance layout and play an important role.Circuit board can be described as printed substrate or printed circuit board (PCB), and English name is (Printed Circuit Board) PCB.Printed circuit board (PCB) is the supplier of electronic devices and components electrical connection.Its development has the history of more than 100 year; Its design mainly layout design; Adopt the major advantage of circuit board to be the mistake greatly reducing wiring and assembling, improve the gentle productive labor rate of Automated water.
The research of the domestic automatic checkout system to printed circuit board (PCB) approximately starts from mid-term at the beginning of the nineties, also at the early-stage.At present, what the scientific research institutions being engaged in this respect research also compared lacks, and because be subject to the impact of various factors, the research for the automatic optical detecting system of defect of printed circuit board also rests on the level of a relative infancy.Just because of the automatic checkout system of external printed circuit board (PCB) is too expensive, and the domestic automatic checkout equipment also not developing truly printed circuit board (PCB), so the way that domestic most board production producer still adopts artificial magnifying glass or projecting apparatus to check carries out inspection side.Because hand inspection labour intensity is large, eyes easily produce fatigue, and percentage of omisson of examination is very high.And along with electronic product is towards miniaturized, digital development, printed circuit board also towards high density, high accuracy development, adopts the method for desk checking, substantially cannot realize.To more high density and precision circuits plate (0.12 × 0.10mm), cannot check completely.The backwardness of detection means, causes the conforming product rate of current domestic multi-layer sheet (8-12 layer) to be only 50,60%.
Rigid Flex is exactly flexible circuit board and rigid wiring board, through operations such as pressings, combines by related process requirement, the wiring board with FPC characteristic and PCB characteristic of formation.But existing rigid-flexible circuit board is when making, and be all utilize pressing machine pressing to form, production process is more complicated.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, the rigid-flexible circuit board that a kind of structure is simple, reasonable in design, easy to use is provided, without the need to pressing machine pressing, the perfect adaptation of Flexible Printed Circuit and rigid wiring board can be realized, and convenient for maintaining, can not damage circuit board body, substantially increase its production efficiency.
For achieving the above object, the technical solution used in the present invention is: it comprises Flexible Printed Circuit and rigid wiring board; Described rigid wiring board is provided with draw-in groove, is provided with a conducting strip in draw-in groove, and the periphery of draw-in groove is provided with a viscous layer, and a side of rigid wiring board is provided with No. three viscous layers; The side of described Flexible Printed Circuit is provided with the fixture block corresponding with draw-in groove, and the periphery of fixture block is provided with No. two viscous layers matched with a viscous layer, and the bottom of fixture block is provided with No. two conducting strips matched with a conducting strip; One side of described Flexible Printed Circuit is provided with No. four viscous layers; The outside of a described viscous layer, No. two viscous layers, No. three viscous layers and No. four viscous layers is equipped with viscous layer diaphragm.
Operation principle of the present invention: when connecting Flexible Printed Circuit and rigid wiring board; directly viscous layer diaphragm is torn; fixture block is coordinated clamping with draw-in groove, without the need to adopting pressing machine pressing; mutually stick between viscous layer; can effectively Flexible Printed Circuit and rigid circuit being hardened, it is as a whole to close, and when keeping in repair, slightly exerts oneself; just both can be separated, can not damaged line plate body.
After adopting said structure, beneficial effect of the present invention is: rigid-flexible circuit board of the present invention, without the need to pressing machine pressing, the perfect adaptation of Flexible Printed Circuit and rigid wiring board can be realized, and convenient for maintaining, can not damage circuit board body, substantially increase its production efficiency, and have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
