Description
Technical field
The present invention relates to printed circuit board production field, more particularly, to a kind of multilayer circuit inner cord production plate
Production method and inner figure data.
Background technology
The production process of multilayer circuit board is usually：Sawing sheet → inner figure → internal layer AOI → pressing → drilling → heavy copper,
Plate electricity → outer graphics → graphic plating → alkali etching → outer layer AOI → welding resistance → character → surface treatment → shaping → silk-screen
Carbon oil → test → FQC → FQA → packaging, wherein, sawing sheet technique is that the substrate aniseed of purchase is divided into several production plates,
Usually optimal sawing sheet size is 41 " * 49 ", afterwards, carry out the typesetting design on production plate, the finished product mainly provided with client
Plate is combined, and the production board of multiple and different functions, line construction and shape is combined, to reach production plate most
Big utilization rate.Inner figure technique first makes the inner figure data of internal layer production plate first, is provided inner figure by mask
The pattern transfer of material is produced on plate to internal layer.Referring to Fig. 1, include multiple production boards in the inner figure data 1 of the prior art
Unit figure 12 (contour pattern of i.e. each production board), each production board unit figure 12 is interior to include production board internal layer circuit figure
Shape 13 (corresponding production board inner plating Shang Youtong areas).Plate is produced using internal layer made of above-mentioned inner figure data, in internal layer
Prepreg and outer copper foil are added on production plate, prepreg is made by heat cure by the method for high temperature and pressure, so that by one
Block or polylith core material are bonded into one block of multi-layer board with copper foil.Since internal layer produces the line pattern skewness on plate, with
And the gap between each production board, cause You Tong areas and without copper area skewness, cause process for pressing Zhong Wutong areas and You Tong areas
Pressure is uneven, produces the defects of copper sheet wrinkles.The solution of the prior art is, as shown in Figure 1：To ignore finished product Slab element figure
The You Tong areas 11 of increase closing form are taken in 12 Zhong Wutong areas of shape, the gap between each production board unit figure, this method
Shortcoming is：(1) when not taking any measure in 12 Zhong Wutong areas of production board unit figure, however it remains pressure is uneven and produces
The defects of copper sheet wrinkles, or exist since the inner figure You Tong areas of both sides have big difference and produce the defects of plate is stuck up；(2) exist
When the You Tong areas 11 of increase closing form are taken in gap between each production board unit figure, the You Tong areas 11 of closing form are pressing
During the flowing of resin can be made to have some setbacks, hinder resin filling dead zone so that cause layering or thickness of slab it is uneven the defects of.
The content of the invention
It is an object of the present invention to solve because the copper sheet that pressure is uneven or both sides You Tong areas having big difference and producing rises
Wrinkle and plate stick up defect.
The second object of the present invention is to solve layering or the thickness of slab inequality defect caused by the You Tong areas of closing form.
To achieve the above object, technical scheme is as follows：
A kind of multilayer circuit board manufacture craft makes the inner figure data of internal layer production plate, including multiple finished product Slab elements
Figure, each production board unit figure is interior to include production board inner line figure, it is characterised in that in adjacent finished product Slab element
Region between figure, or region between adjacent production board unit figure and in production board unit figure without into
The region of product inner cord line pattern is provided with the circular pattern of one or more equidistant arrangements, the circular pattern and it is described into
Product inner cord line pattern corresponds to internal layer production plate Shang Youtong areas, a diameter of 1.25mm of the circular pattern, adjacent circular
Distance of center circle between figure is 1.5mm, the circular pattern with the production board unit figure or with the production board internal layer circuit
The distance of figure is more than or equal to 1.5mm.
A kind of production method of multilayer circuit inner cord production plate, it is characterised in that using the internal layer described in claim 1
Inner figure is transferred on internal layer production plate by graphic documentation, in production board unit figure, production board inner line figure and circle
The corresponding region of shape figure forms internal layer production plate Shang Youtong areas.
From above-mentioned technical proposal it can be seen that：By internal layer produce plate except rationally dosing in conductive pattern Wai Wutong areas
Circular copper sheet array, can improve because copper sheet corrugation that circuit skewness or both sides You Tong areas having big difference and producing and plate are stuck up
Defect, and replaces whole copper sheet for closing with circular copper sheet array, the filling that can make resin evenly, can improve internal layer
The planarization of plate pressing is produced, improves the performance of multilayer circuit board.
