In order to ensure in pinup picture process, when components and parts being imported PCB design interface, device item mates with the correct of edge shape, the corresponding relation of each components and parts edge shape and corresponding device item can be pre-set, and after components and parts are imported PCB design interface, according to the described corresponding relation obtained, when detecting that target devices item does not mate with corresponding object edge shape, described target devices item is adjusted in corresponding described object edge shape, thus ensure that the correct relation of device item and respective edges shape, ensure that the correctness of PCB design.
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 2, embodiments provide a kind of components and parts chart pasting method based on PCB design, the method can comprise the following steps:
Step 201: draw PCB drawing, wherein, PCB drawing comprises multiple components and parts; The device item that each components and parts are corresponding is set.
In the present embodiment, first PCB design needs to draw PCB drawing, and wherein, this PCB can comprise multiple components and parts in charting, such as, and the components and parts such as resistance, electric capacity, chip and/or power supply.
In the present embodiment, in order in subsequent process, different components and parts can be distinguished, the device item that each components and parts are corresponding can be set.Such as, the device item of resistance 1 is R428, and the device item of resistance 2 is R450, and the device item of electric capacity 1 is C354 etc.
Step 202: obtain a layer as silk-screen layer in PCB design layer.
In the present embodiment, in PCB design process, multiple PCB design layer can be comprised, such as, top layer, bottom, double exposure once, silk-screen layer etc., wherein, above-mentioned PCB drawing is arranged on wherein one deck of PCB design layer equally.Order between PCB design layer is not fixed, and only need, after PCB design terminates, corresponding PCB design layer be marked upper.
Wherein, silk-screen layer is generally used for the annotation to each components and parts in PCB drawing.
Step 203: on silk-screen layer, charts according to pre-rendered PCB, and the position of each components and parts is drawn edge shape and the device item of corresponding components and parts.
In the present embodiment, edge shape, for drawing out the edge block diagram of components and parts, indicates position for the pinup picture for components and parts.
In the present embodiment, according to presetting rule, device item can be positioned within the shape of corresponding edge, also can be positioned at the adjacent locations of edge shape.
Be positioned within the shape of corresponding edge to set rule for device item, the position relationship of the device item in the present embodiment and edge shape is described.
As shown in Figure 3, be the edge shape of each components and parts and the schematic diagram of device item of drafting.The position relationship of each components and parts in PCB drawing can be learnt according to Fig. 3.
Because device item has overflowed edge shape limited range in figure 3, therefore, in the present embodiment, the font size of device item can be set and the width of the description line for stating device item and/or edge shape is set.
Such as, the width arranging the description line for stating edge shape is that width equals 1; The width arranged for the description line of stating device item is that width equals 4.
In the present embodiment, in order to the one_to_one corresponding of the edge shape and device item that ensure each components and parts, arrange and store the corresponding relation of each components and parts edge shape and corresponding device item.
Step 204: according to PCB drawing, the components and parts related in being charted by PCB import in PCB design interface.
Step 205: according to the corresponding relation of each components and parts edge shape pre-set and corresponding device item, whether the device item detecting each components and parts mates with corresponding object edge shape, if do not mate, performs step 206, otherwise, perform step 207.
Because when components and parts being imported PCB design interface, the position, direction etc. of device item may change, if and manually the device item changed is adjusted, adjustment mistake may be caused and efficiency is lower, thus cause in follow-up pinup picture process, the pinup picture mistake of components and parts.Therefore, after being imported to by components and parts in PCB design interface, before the pinup picture of components and parts, whether the device item detecting each components and parts mates with corresponding edge shape.
In the present embodiment, to detect in following three kinds of phenomenons wherein one or more time, show that the device item of components and parts does not mate with corresponding edge shape: 1, detect the device item of each components and parts not in corresponding edge shape; 2, detect that target devices item direction changes; 3, detect that target devices item position changes.
Step 206: according to the rule of setting, the relation between device item and corresponding edge shape is adjusted, and performs step 207.
In the present embodiment, if the device item that setting rule is components and parts is positioned at edge shape, so there occurs in three kinds of phenomenons in step 205 when the device item of certain components and parts one or more time, the device item of these components and parts is adjusted in corresponding edge shape, thus ensure that the accuracy rate of follow-up pinup picture, and automatically carry out detection adjustment by device, improve regulated efficiency.
As shown in Figure 4, for the present embodiment provide the relation between device item and edge shape is adjusted after schematic diagram.According to Fig. 4, after adjustment, device item is positioned within edge shape, and device item does not overflow edge shape limited range.
Step 207: the device item corresponding according to each components and parts pre-set, is pasted into corresponding components and parts in the edge shape that this device item is corresponding.
According to such scheme, by obtaining a layer as silk-screen layer in PCB design layer, thus on this silk-screen layer, chart according to pre-rendered PCB, the position of each components and parts is drawn edge shape and the device item of corresponding components and parts, and according to edge shape corresponding to each components and parts and device item, the position of each components and parts is pasted into corresponding components and parts, thus ensure that correct components and parts pinup picture, ensure that the accuracy rate of PCB design.
