pcb 抄板方法及步骤（Method and steps of PCB plate drawing） pcb 抄板方法及步骤(Method and steps of PCB plate drawing) PCB plate removal method and steps Now there are many software designs for PCB board circuits, such as PORTEL 99. POWER PCB However, if you want to copy a ready-made PCB, use the software to copy, may appear, in fact, in today's electronic industry, need to copy a PCB line is frequent, under normal circumstances, we will put the PCB board to PCB factory to give us copy, but if we want to make some small changes in the line, it is more troublesome. At present, some software copy boards are used in industry specific software, can not you literally can be downloaded from the Internet or from the software market to buy, some time ago I want to be a product the PCB line slightly adjust the method, so I deliberately on a copy board Required equipment: scanner, computer, need to install PORTEL 99 and AUTOCAD software 1. first you want to copy board PCB board into the scanner, start the scanner, pay attention to adjust brightness and contrast in the scanner and so on 2. open AUTO CAD software, build a new CAD file, insert the bitmap image in the Insert menu, select the image you want to insert, insert the image dialog box, select the ratio of 1:1. in the dialog box After the 3. into the PCB image to draw a rectangle frame map of the PCB frame to set, pay attention to use when painting frame object tracking object lock, if not draw frame, in the process of tracing lines in image accidentally move, you can set the rare. 4. drawing element package, because we want to copy the PCB board, the component package of a component package PORTEL 99 agreement, so we should establish their own packaging components, we will draw out to draw the PCB elements in the shape of drawing element package, we must first count PCB board with the number of packages, each package just painted a variety of packages, are painted, it will be transferred to PORTEL in 99 further processing. 5. open PORTEL99, first create a PCB file, then import the CAD file in the PORTEL 99 PCB File menu editor, the painted CAD file element model guide in import after the success of the PORTEL 99 PCB editor appeared basic graphic component package. 6. in PORTEL99 create a PCB component editor, then open the PCB component editor. A new element, and then from the PORTEL99 PCB editor to choose a component package is copied to the PCB element in the editor components. 7. all the component packages are finished, and then put these packages placed in the PORTEL99 PCB editor inside, and then export it to a CAD file 8. open the CAD file this component package diagram, and then import the CAD file before the PCB image is also open, and will be copied to the component package diagram with PCB pictures CAD, then close the only component package diagram of CAD files, only need to work in the CAD file with PCB pictures, and the placement angle according to the position of PCB graph element, line components, pay attention to make more sub element method for copy and paste. The 9. placed pads and vias: place the component package, the next job is to place the pads and vias, the first inner diameter and outer diameter of well pads measured in CAD, then in the graphics menu, select the item and determine the garden ring, inside and outside the ring, to be the same size as the size of welding put in place after the disc one-time pad pad pad, but square and polygon can not be placed, although the filling method is available in the CAD in the polygon fill into the entity, but the entity to filling PORTEL 99 after there will only be an empty frame. Therefore, if there is a polygon in PCB pad, we can use lines to pad edge trace, pad to PORTEL 99 and then put on the corresponding. 10. draw the line: after the pad is drawn, start to draw the line, draw the line is drawn with polymerization line, in the drawing menu, select the polymerization line, determine the starting line width and termination width of the polymerization line, Then start drawing in the drawing process, if it is to choose the orthogonal straight walk the line, if it is 45 degrees or other point of view, to cancel the orthogonal alignment. If the entire circuit board line width is only several specifications, we can also use ordinary lines to draw, but not to the same width in different layers, to PORTEL 99 and then edit the line width. 11. when the line is completed, we were finally working in CAD placement of the silk screen, if it is a text placed text box to achieve, if some screen irregular lines, with a polyline, of course you have to direct the use of lines to draw, to 99 after PORTEL to edit the line width. Through the above 12. steps, has been basically completed in the CAD work, if you do not go to the PORTEL can also help you do business by PCB board, you can be what you need to make your printed layer, PCB, of course, ultimately I wrote this article is to tell the reader that the map to PORTEL in several steps, so we should continue the following. 13. open PORTEL 99 CAD file into the PCB editor, you have drawn attention to the line, corresponding to the various levels of PORTEL 99 in the CAD dialog box in each layer of the import file, this is a very important point, whether you are in the CAD layer is the name of what, but you must know this layer to deal with what is the PORTEL 99 layer, if not controlled by chaos, you will spend more time for the conversion layer in PORTEL 99, the default width also import the best and change. 14. the last edit, import PORTEL 99, but also the appropriate editing, for example, we will import lines and pads are placed in the TOP LAYER layer, then you should pad all in the MULTI LAVER layer, there is no matter you in CAD will be transferred to the printing text which angle, go to PORTEL 99 are positive, then you have to control the physical PCB adjustment. 15. if there is another side to the line or screen, just according to the above method to do a good job, and then guide to PORTEL 99 integration, pay attention to the mirror oh. Finally control pictures or PCB check, you can also be accomplished by appropriate modifications. Note: in the CAD if you move the picture, then you will see the painting line all disappeared, then you will remove all the pictures, and then you select all the lines, and then moved to the picture on the line, pay attention to the selection of object tracking and object lock. This can only be set well. The above is the practical experience in my work, the copy board accuracy is really high, as long as you have patience, more complex lines can be done. The following is my last work when the commemorative card Note: I know that you want pictures in JPEG format, and if you want to send the artwork from this WORD, you just save the WORD file into a WEB format
