Gold wire bonding pads
606 1
Hi all! I am drawing my first PCB for the use as a carrier board for a gas sensor. I work in gas sensor development. The gas sensor is a stack of heater, thermoelement and a metal oxide layer on top of a silicon substrate. The silicon substrate onto which the metal oxide layer is deposited contains an electrode system. The electrodes are connected to bond pads. On the PCB I have drawn corresponding wire bond pads (solid areas) which are connected to male header pins. My question is, what layer should i define the solid areas so that these areas are the top layer and can be used as wire bond pads? If my description is not up to your standard, I am sorry and I will revise :-). Thanks in advance! Best regards Robert

You need to first create a PCB Footprint with a suitable silkscreen outline and your desired arrangement of Top layer pads. Top layer Pads will form single layer pads (with no hole in them) on the top layer. You then needs to create a Schematic symbol with the same name as your PCB Footprint with the desired pin arrangements (they must have the same numbers as the pads in the footprint but they do not have to be in the same placement: the symbol is a convenience for drawing a clear schematic. The footprint must be correct to the real, physical device. When you create the Schematic Symbol you must assign the name of the PCB Footprint to it using the Footprint Manager. Then you are ready to draw your schematic into which you place the Schematic Symbol so that when you do Convert to PCB, EasyEDA pulls the correct PCB Footprint(s) into your PCB ready for your to position them and then connect them up by routing copper traces. To learn how to do this please read (1), (2.2) and (2.3) 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) I recommend you start with a dummy project just to learn from before you start a real or more complex project. When you have completed your schematic you must go through the Essential checks listed in (4) in the above link. Then, when you have completed your PCB you must go through the Essential checks listed in (6) in the above link. Have fun!
