    Help-- how to flash the PADs in PCB when creating gerber file?

    naiwu.yuan

      Dear all,

       

      I created gerber files for PCB manufacture and checked the gerber file by "ctrl+shif+o" in "viewmate", it is shown that not all pads are flashed.

       

      I want to change those non-flashed pads into flashed and tried different methods, but I couldn't find the setup to change the non-flashed pads.

       

      What's more, it is stange that there are both flashed pads and non-flshed pads even in one component.

       

      Could you please help me?

       

      Thanks a lot

          Naiwu,

          Noramally,  all pads should be in flash mode,not in  draw mode for 274X,  because circle and rectangle are primitives. I guess you just mean some pads of the components are missed in gerber file.

          For this symptom, you can check your setting for unconnected pads'output.

            Thanks, Yanfeng

             

            I double checked my gerber file. All pads could be found by viewmate. But, when I selected "pads contrast", some pads(around 30-40%) keep same colour with tracks while other is highlighted.

             

            I am not sure if your mentioned "missing pads" are the pads which couldn't be read in Gerber file.  or something else?

             

            Regards

              Naiwu,

              I got understand, but I am' not familiar with Viewmate. I suggest that you check your gerber in other viewing tools such as popular CAM350 or Gerbtool. Aslo there are some free viewing tools. If post the sample gerber here, I can help to validate the symptom.

                Yanfeng,

                 

                I downloaded the CAM350 9.1 and checked that gerber file by CAM350. Similar result could be found. Please refer to attached picture showing the result.

                 

                Two green circles indicate the pads. The left circle include both flashed pads and non-flashed pads even the two pads belong to one components. The right circle include a common SMT LED which two pads are both non-flashed.

                 

                Thanks for your help

                 

                Please could I know you are in China or oversea?

                 

                Regards

                  Flash is a rather antiquated concept, and dates from when Gerber plotters had aperture disks, and really did

                  Flash a PAD. Given that nothing today actually plots with an Aperture Disk, why does this matter to you ?

                   

                  One of your examples appears to be rotated <>90', and those parts cannot flash (or drag either) as

                  the Gerber has no concept of a rotated flash. So pads creates the area fill itself, and you can set the

                  width used for this.

                   

                  Oval pads will drag a circle, rather than flash, because that's what thephotoplotter does.

                   

                  If you want the most accurate pads, enable area fill on PADS, but do NOT enable area fill on the

                  whole design. Doing that gives a small saving on file size (who cares?), but gives a BIG

                  risk exposure to the CAM tools - I've seen CAM tools area fill in the WRONG order, and

                  so create a flawed PCB, from perfectly good gerber data,

                   

                  Moral: Keep it simple, and get CAM tools to do as little as possible.

                    Hi Naiwu,

                     

                    I can't exactly tell why your gerber display in such way until I get the gerber data.  Just like what Jim said, There was no expression for the rotation definition of flash  in older Gerber 274 Spec  and the layout tool will output it in draw mode, except you dine it's shape for the D-code , and most of Layout tool does't support to difine a polygon for the flash at all.

                     

                    Things get evoluted. The R274X support the rotation flash. Below is a sample data, you will see two squres of 0.04 inch x 0.04 inch, 12.3 Degree angle in flash mode in your gerber tool

                    I stopped to use Powerpcb nearly nine years and forgot it's algorithm for the cam out. However, You can check the plotter setting. I

                    suggest that you use R274X instead of R274D and try to don't select the "seperate Flash/Line" on to see the difference.

                     

                    Definitely, I live in China(See the poor English)

                      Thanks, Jim and Yanfeng

                       

                      Our PCB manufacturer want to the pads physically by the flashed pads. However, it could be more important to find the root cause than the application.

                       

                      I checked the output setup of CAM which is RS-274X and tried to modify the setup by "use fill mode" or "use aperture macros". No better result was got.

                       

                      A simple PCB was drawn to verify the effect of direction, please refer to attached picture. From the drawing, it could be seen that 0603 pads could be recognized when it is horizontal. But, the 0805 or another bigger components couldn'?

                       

                      Following is the gerber data corresponding the board. To be honest, I can't understand it. Could you help me to find the root cause?

                       

                      Thanks a lot.

                       

                      Have a good weekend.

                        Hi Naiwu,

                         

                        It is clear that this symptom was caused by the limited list of D-codes. You should generated all D-codes for your design.

                         

                        In Photo Plotter Setup dialog, If you click the button labled as "Augement"(Based on my memories), Pads will automatically generate the ful list of

                        D-codes for the current design. With the full list of D-codes, all pads now in fash mode.

                          Many thanks. Yanfeng,

                           

                          Most of the pads are flashed normally according to your methods.

                           

                           

                          Furhter to last board, the updated board picture and codes are attached here. The only remaining pads is the circled one which is not in horizontal or vertical position even I used 274X format.

                           

                          Are there any method to flash the pads?

                           

                           

                          In addtion, here to share some special experiences in the process. When I "Augment" a complicated PCB, the gerber file show a very strange shape in which all tracks, pads and cooper are thrown into confusion.

                           

                          Then I modified the "number of digits". It became normal after modifying the "leading" from 2 to 4 and "trailing" from 3 to 4.  But I don't know the reason how the number of digits effect the gerber file. Do you have similar experiences?

                           

                           

                          Regards

                           

                          Naiwu

                            Naiwu,

                             

                            Pads may don't support to output rotated rectagle pads in fash.

                            Not all Gerber viewing tool can always recognize the decimal format of gerber data, so it's your duty to tell what format is for your gerber when reading into the viewing tool.

                              Daiwu,

                              My memory wake up now. Powerpcb suppourted D-Code Macro.PLease select "Use Aperture Macro" in the plotter setup, And don't use Fill mode just like what Jim told.

                                Thanks, Yanfeng "Qian Bei"

                                 

                                I tried it again after selecting "Use Aperture Macro" and unselecting "Fill mode". The gerber view is same.

                                 

                                However, the gerber code is a little different, which is attached as following.

                                  Naiwu,

                                   

                                  The problem is only in you side, not the program. If you change the setting( for example, select to use apture macro etc), please don't forget to regenerat or argument the D codes or select generated-on-the-fly, to make Powerpcb generated a new list of D codes to matching your setting. If you forgot do such thing, it will use old D codes.

                                  Let's stop to disuss this problem. I think you can learn more from this thread.

                                    Your comments lead me to some fields which I didn't know before.
