You need to use EasyEDA editor to create some projects before publishing
basic question

Hi I'm very new here and have no background in PCB design although I have printed a couple small PCB's for myself using my printer. I'm laying out a very simple PCB to make my life a little bit easier and also allow me to deploy my project without an Arduino, I'm sure you've all done this. So im basically placing one chip in the middle of the board and doing traces and connection points "pads" mostly for header pins and a few components. My question is when I placed a chip that has 16 pins on it does that automatically create the pads and through holes it needs or do I need to create that on the PCB and then place the chip in that spot? I hope that is easy to understand... in other words if I don't manually create the pads and just place the chip in my project is the PCV gonna come back to me with a big blank spot lol? Or is the manufacturer going to see the hole positions? I know it's a pretty simple question but like I say I don't have a background in this I do have some background in mechanical engineering in the robotics industry but I have done nothing electronic design other than designing cables. So thank you in advance jeff

Hi Jeff, Welcome to EasyEDA. You'll save yourself a lot of time and frustration by reading: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> and the documents that it links to.  In your case by paying particular attention to (2.2) in (2) in the above. The short answer is that you need to start off by drawing a schematic into which you place the schematic symbols for all the components that you want on the PCB. Make sure that the symbols (a) have all the correct Bill of Materials  information filled in for them about the supplier and manufacturer part numbers and that they are assigned the correct PCB footprints with all the symbol pin to footprint pad mapping and numbering correct to the original manufacturer's datasheets. Then when you do Convert to PCB, the PCB will pull in all the correct Footprints with the pads correctly mapped so that the connectivity of the PCB matches that which you intend in your schematic. Then all you have to do is route copper tracks to complete the connections shown by the ratlines. To help avoid mistakes please follow the essential checks shown in (4) and (5) in (2) in the above.

thank you, ill read everything today. the reason I was trying to take a short route two a simple PCB is because it's going to be very very simple basically 2 2 pin connectors basically just headers 1 4 pin connector, an led, a cap and one resistor, since I believe this to be the only PCB then I'll probably ever make in my entire life other than the couple that I made from my printer I figured it would be quicker and easier just to ask the question for this one 10 minutes project then two learn an entire program LOL

You can make the PCB directly in the PCB Editor just by finding and placing the required Footprints. To do that with some chance of retaining your sanity, you need to read: [https://easyeda\.com/forum/topic/How\_does\_the\_Connect\_Pad\_to\_Pad\_tool\_work\_\-JgQO0Ay7H](https://easyeda.com/forum/topic/How_does_the_Connect_Pad_to_Pad_tool_work_-JgQO0Ay7H)<br> <br> You might still want to read (2.3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> to get some idea of why library parts can seem somewhat elusive... :)

Yeah I noticed it's hard to make out some of the parts and find them. For example I found a stepper control that does not share the same naming convention buddies physically identical both in function and footprint. That's why I'm trying to figure out if I place the part does that create the hole? Thank you again I will keep reading.

If the footprint is correctly constructed to the information given in the original manufacturer's datasheet then it will pull all the correct pad and hole types, dimensions and positions straight into the PCB when it is placed. However it is important the check every footprint taken from any library to make sure that the above statement is true!

I decided to go a different route. I found the exact correct part pulled it into the drawing snapped it into place make sure it lined up with all the connections and then Drew pads for it and removed it from the drawing this way it's going to keep it very simple I'm going to have a tiny 40x40 mm board that is just holes/pads and a little bit of artwork. Very very simple stuff and it'll serve my purposes for the devices that I'm making for personal use. At the same time I'm going to try and print some myself using the old method with a laser printer. I got very very very good results the last time I tried it but I wouldn't mind having professional boards for my final implementation and deployment I want to thank you for all your help It's really appreciated honestly Jeff
