Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

Anyone messing with Design spark PCB files? Just getting started with them to get beyond the Diptrace demo limitations. I want to get a board done with no solder mask on the bottom layer of a double-sided board. The bottom layer will be all gnd plane, no vias or tracks. Will there have a PCB fab accept gerbers without the bottom solder mask layer?

There are three options about the solder mask supplied by PCB manufactuerers: none, top only and bottom only. If you select one of the options the PCB will be manufactured that way.

Instead of making through-hole connector solder pads you can use self created solder pads which have to be on component side, the same as for the LED.

I would appreciate a lot getting a photo of your project. No solder mask on the bottom normally means there is absolutely no wired component in the design.
