pitch number 100 play create a ball release precision what it is board very precision how it is useful while we are speaking about this board release procedure can be for example a document which describe the steps which you should be doing when you are finishing your project yes when you are finishing your project you need to generate some documents need to go through some steps check there are no errors and this kind of stuff yeah and if you don't create any document about this sometimes may remember sometimes you might forget so who knows yeah this is exactly how what was happening when I was talking with table design we never had ball release procedure so sometimes I'm jealous I generated documents and only one was missing sometimes I generated documents and two or three were missing the end piece is everything was easy when I'm starting but then it is not the proper way to do it because always when you forget something you need to do it later you need to go back to your project you need to generate it there are some D like maybe you by mistake you forget to do something really important like grandiosity check or something yes you don't want to forget and ERC check before you release the document so then when I move to a bigger company so in the in my first job we never had easily this procedure then when I move to the bigger company they head-body this procedure and this when I first time land maybe I should be doing something like this but I have to tell you that I never really like body with procedures because it's kind of boring sometimes it takes day to generate all the documentation and you know you find a mistake then you need to fix it and then you need to do it all again if yes but it has to be done when I when I like to company and I when I set up my own company and I started designing for clients kind of influencing one of the first things what I created was bought release procedure because I wanted to be sure that always when I generate the document from the project I've always wanted to be sure that when someone takes all the documents generated during ball release precision you can they cannot take them and they can manufacture board based on the documents without asking you any questions this is the goal of board various procedure I'm going to show you how we do it in our company so you can get idea with you may want to include in the board this procedure so have a look we are speaking about our directory structure in different tip so this is how our project will look in the release directory you will find that all these sub directories and you will find that also this document this is the release document and we can read it together so follow this procedure before releasing files contain reaction with your initials and date it's very important that all the states are signed by someone because someone always has to be responsible for the final document if nothing is wrong you know who is going to decline who is responsible for or checking the finalcad best someone has to be so put the initials end date under each step if any changes needs to be done start the procedure from beginning this is what I don't really like but I think it's a very important yes if you are in middle of generating documents and if you if you find out that there is something wrong and you need to change something in the schematic then you really need to start from beginning because as you can see here very first step is compile the project and see if there are no errors so if you change something in the schematic you really should compile the projects and see if you have not created any new terrors you cannot just continue generating rest of the document you need to start from beginning so I don't really like this but it's necessary now the procedure needs to be executive in order and define here that's another one so another one right click on the project company project this is about a few but isn't basically the assets check of the project yes check on the schematic once you do it then you go into a PCB and then update the document this means your schematic is fully in synchronization with your PCB you do not make changes in somatic and then find out your PCB differences implants so you check I can feel I have updated in track track with gap to Madeira quality penance you check your PCB you dragged into PCB with the information provided by your PCB manufacturer and you compare if the impedance in and track three not is correct sometimes may happen that you have this document from PCB manufacturer but you forget to my channel update Drag Week in your PCB then you know in two thousand your PCB will not be correct because it doesn't follow document from your PCB house so you need to double check the tracks if they have the correct impedance you can have the correct geometry Lam tools polygon poles rebuilt all you need to be sure that all the polygons have been updated now Ram tools design rules around is a little that you need to be sure to ram this is rule check in your PCB so there are no violations get bad check so you can feel that your generated altogether pass and you had a look on the garbage fast and they all seems to be correct and in the step seven generate the other files in write coffee I help opt check files play in some directories so these last two steps they actually have some substance and if you go if you follow our federal directory structure if you go inside for example step one you will find that this readme file where description what you should be what you should include in all these directories so in this PCB manufacturing directory inside included the PCB stack-up yeah so you need to put it here then you go inside this cable called directory and I don't have it here because I do it in the readme file when I was uniting together and you would find there there is description that you need to procure before here then here here is the file so you need to put here or some screenshots where you solve the PC manufacturer where are the specific differences where are the clock respecting appearances name then different directory real fast okay and as you can see then you just follow all the directories you follow all the readme files and test I will generate all the documents which are needed for someone to build your board in all these readme files that is everything there is no way you forget to generate something if there is a missing document if someone asked us ok we will need also this very special bomb we add this into our release processor so next time we generated automatically then we are not going to forget about this file there is so many information just here see generate this list is this there are so many information during this release procedure that you may not be surprised it when I was talking with hydrogen I always forget something because I didn't have this list because there are so many things you I always find something this ball release procedure is extremely so is very useful just listing all documents that you need to generate let's solve useful as I say you don't really want to forget run by the no design rule check before you start doing this release process so it's very important ok I mean pretty sure you understand how important it is it's so boring to do it it's so annoying sometimes when you have to start again but it's all important that's why I chose thesis at the tip number 100 because I think it's very important this number 100 create a board really procedure why you really want to be sure that you have done all the necessary steps and you have generated all the document
