Suggest you study the PCB layout in **boost\_converter\_PCB\.pdf**, used by the author from: [http://uzzors2k\.4hv\.org/projectfiles/450vboostconverter/Boost\_Converter\_PCB\.zip](http://uzzors2k.4hv.org/projectfiles/450vboostconverter/Boost_Converter_PCB.zip) There are errors:  check the Design Manager.

Hi thank you for the reply! I have fixed the errors and have studied the pcb that you sent me and Im not seeing anything wrong but having a second eye to check would be great just to ensure that I have it all corect. [https://easyeda.com/johnronald431/capacitor-charger](https://easyeda.com/johnronald431/capacitor-charger)

"...have studied the pcb that you sent me and Im not seeing anything wrong..." It is not the PCB that I sent you. It is the PCB layout designed by the original author of the project.and that that you should have studied before you started your own PCB layout. You must look at more than the connectivity before you can say you can see nothing wrong with your own PCB. You should look at component placement, spacing, track widths, routing and the use of copper areas and or copper planes and then compare them with your own hugely spaced out  layout with minimalist track widths. You are building a high voltage switching power supply so you need to understand the voltages that are going to appear on your circuit, the currents that are circulating round your traces, the edge speeds due to the switching, the over and undershoots that you may encounter due to the effects of those fast voltage and current edges interacting with the stray and parasitic capacitances and inductances especially due to the use of inadequate trace widths and poor layout practices.switching. From the look of your PCB at present, you need to stop what you are doing and spend some time to learn more about good PCB design practices. BTW, your title for this topic is misleading: you have not designed a PCB from a schematic in the sense that you have - as has been suggested elsewhere in a reply to what is essentially another post by you on the same topic -reproduced the schematic in EasyEDA and then used that to help you design the PCB. All you have done is draw a PCB directly in the PCB Editor from what is basically a picture of a schematic. * We do not recommend this approach to PCB design for reasons that are made clear ion the documents in the link I posted above.

There are lots of resources available for learning about PCB design especially for SMPS layout. Try searching for "pcb design for smps"
