PCB design review

In the old days, when PCB CAD software was new, we would go through and check the layout against the schematic to make sure all the connections were made.  Now, the software is pretty sophisticated and will most likely catch any disconnected nets. 

If you are working on a team and there are others that have knowledge of the design then having them review the layout for compliance with design notes, component vendor layout notes, and best practices is a good idea.  If you're working alone, that's not usually an option.  Also, you can submit the layout to a PCB company for DFM (design for manufacturing) review.  Usually this is free and will give you an indication if there is anything in the layout which will hinder manufacturing.  It will also tell you if you fit into a certain category of pricing for PCBs such as trace/space requirements, number of vias, minimum/maximum drill sizes, etc.

Hope this helps.  In the end, the best way to find if a PCB is good or not is to build one and test it.  All of the above just helps to catch dumb mistakes before you build and save time, money, etc.

Thanks for your reply !

But my another great doubt is : I designed a PCB and I'm going to manufacture it by giving my design to supplier. What are the process needed to be done before manufacturing. For e.g.: DFM, DFT, etc.

Thanks in advance !
