The first note is that the encapsulated library file is stored under Allegro, not orcad. allegro is a PCB painting tool, and orcad is a Sch painting software that can generate a variety of network tables. after Allegro is installed, the built-in library file path is: C:/Cadence/spb_15.5/share/PCB/pcb_lib/symbols (my files are installed on the C drive, and other disks are similar)
The files under symbols are library files. In fact, the library files of Allegro are useful files with the suffixes of DRA and SMS. one problem that needs to be explained here is that when we learn Protel, we know that the Protel library file is integrated, that is, the Korean disk and encapsulation are ready-made. Generally, the call is OK, however, Allegro uses Korean disks first, and then calls the welding pad just made during encapsulation. the tool used for pad welding is Allegro spb15.5/PCB editor utilities/PAD designer. This tool is dedicated to pad welding. For details, refer to relevant reference books and save it at a certain position, it will be called during future encapsulation. If beginners are not familiar with Allegro software, they will save the prepared results in C: /Cadence/spb_15.5/share/PCB/pcb_lib/Symbols somewhere, because Allegro first finds the pad drops here by default. as for the process of encapsulation, generally follow the Wizard to do, here I want to say is, http://www.pcbbbs.com/d Ispbbs. asp? Boardid = 42 & id = 98354 & page = 2
On the forum, a master made a small software, directly changed the parameters in the software, then directly generated the encapsulation, and then saved the C: /Cadence/spb_15.5/share/PCB/pcb_lib/symbols (why is it stored ). during Sch, fill in the encapsulated name to the appropriate place. then generate a network table. I will tell you how to pre-cable the encapsulated library files carried by Allegro.
1. open the alllegro software and click manually, the first item under place... jump out of a placement box, click Advanced Settings, check the library, click the placement list, and replace components by refdes with package symbols, followed by a cross, click open, you will see a lot of packages. If you want to check the packages, you can hook them in the front box. They will be displayed in the black box in the lower right corner, and can also be placed on the board. if you want to use these packages in SCH, write down the names of these packages in the package items of the components.
2. What about self-painted packages? I just mentioned that I could automatically generate a lot of encapsulation libraries by modifying the software on the Internet, and save it in the C:/Cadence/spb_15.5/share/PCB/pcb_lib/Symbols location. why is it stored here? After the software is installed, encapsulate the default storage location on the C drive (self-built directory). Of course, you can also change the default location, for more information, see Allegro/Setup/user preferences. Click "4th confi_patch" on the left, and modify the number of confi_patch items on the right. Based on my personal suggestions, follow these steps: A newbie generally doesn't want to change this place. Put the library files (or the files changed with the master software) as mentioned above in C: /Cadence/spb_15.5/share/PCB/pcb_lib/symbols. this is because I have changed a lot for the first time. Now this software is not very useful, and I don't know how to change it back. (solved) 3. create a folder by yourself, store the installed pad and encapsulated files in this folder, and use it as another library folder (the system already comes with one). Open Allegro/Setup/user preferences, click designer paths on the left, and then click valu in padpath and psmpath on the right. Add the folder in E. In this way, the new package you saved can be used in your PCB.
