What does the term voiding mean? Low temperature lead free solder paste 8 Wastes of Lean Manufacturing What software is available to view Gerber data? Highlight the file format which is to be exported from the list.
In the editor MAX Board input, highlight the name of the. The name of the highlighted file is in the file name edit box and by default it is given the suffix. Click Save. In the Options Editor, check the box "All of the above" to process everything in the file. Click the OK button. Destination name and location. Number of layers, padstacks, nets, etc. If any errors occurred. See the requirements for Cadence Allegro. If not present already this prompts the user to download the Valor ODB script writer which then prompt the user to open the job file and produce the ODB output.
The Test Expert script file describes the data to be extracted from the database.. This script formats the data in a VERY specific way, which means that the file extracted using one Company's script will NOT work with another Company's software because although they may look 'similar' they are not is the expected format or column order.
Also you cannot simply re-order the columns because we require a number of sections with different information Part, Net, Package etc etc.
In order to do this, the customer needs the Fabmaster "extraction script" and instructions. This script must be run on the computer that has Cadence loaded on it. Windows: They need to extract this zip folder and it will produce a folder called Fabmaster'. This starts the installation process. It is best to accept the defaults but to check the configuration file paths to the Cadence system libraries etc Then ask to view the readme file. It's best to print it out. It then tells you how to run the program.
The important thing is to make sure that the final file looks like the sample file attached. A Cadence for Unix file header should look something like this:. A Cadence for Windows file should look something like this:. If the extracted files don't look basically like this, they are not right and it will not import into Fabmaster or TestExpert Once the file has been produced it is transferred to the Test Expert system and run using the CADENCE input processor.
PAF, for example: cads Select open :. From this dialog, you can choose the name of the output file to be generated. Use the browse entry box to name the file and choose the folder location where you wish to save to. Select the option: ALL. Select GO. This file should be renamed. PAD before it is transferred to prevent confusion with other file names used by Test Expert. A sample listing of the contents of this file is supplied at the end of the datasheet. Instead, use Mils. A sample of the header file follows.
Select Units Select Current Units. Special Options Select Include Attributes. This is defined as a standard default on the CAD system but may typically be say 3 thou, so a 20 thou pad will have a 23 thou solder relief aperture, but this could vary for different PADS users and for use with different PCB manufacturers. Importantly the data held here is not used until the Gerber files are generated.
The customer CAD Engineer may have valid reasons not to make these manual changes to the global defaults apart from having to create the exception for every relevant shape, which means additional work. Zuken's CDB software uses binary databases.
An FTF file looks something like this :. If the File begins 2 39 this is Version 13 , in this case the file will need to be converted using free-issue files from Vutrax to downversion to version 12 or version By default, the input processor recognises and processes files with the suffix.
This file with the suffix. Return to home page.
It's quite an interesting one. This is my first visit here and i am really inspired with your writing skill. Hi Thank that lot of good info.. Part No. Best regard Marc L.
