Understand that top silk and top copper are included in the price. It is more common to put the silk screen on the top for parts placement, rather than on the bottom. Plus, with BatchPCB, putting your board outline in the top copper or top silk is best. I like a zero width shape for that.
Oh, my silkscreen is on top, as per standard. I was just wondering if a top solder layer and solder mask was of any use for a bottom solder design. I’ll just keep it.
It is important that you not send the layer (probably your assembly layer) that shows the pot and switch outlines outside of the board shape to BatchPCB.
Already QA’d that. That would be a blunder!
I would use a larger gap in the pads of your round capacitors. This will make your had soldering less critical. I like to make the positive pads on electrolytic caps rectangular. I would move your ‘+’ signs away from the pads. Silk screening over pads will not print; the pads have priority.
Good to know, thanks. The polarized caps come from a library by Panasonic, which are the make of the caps I’m using. Maybe I’ll make my own. The 3.5mm jack and pot are both my own parts.
Is that a header/connector for the battery? If not, and if you are soldering wires, I would increase the separation. If you are using a connector, then no problem.
It is, and I do intend to use a connector.
I wonder about the two pads labeled “tuner”. That function would normally be part of a receiver, so I wonder what kind of device that is.
The tuner utilizes a very large and heavy variable capacitor (in parallel with a loopstick). I didn’t want to add that to the board. I’m not going to put this in a case, I’ll mount everything on a piece or wood or something else to show off the “guts”, hence the separation. As for the device, it’s a simple AM receiver. Two-stage RF amplifier, envelope detector, single-stage AF amplifier.
Is this is a learning tool for you in making boards, I would try to fit this to a smaller board. If it is a training board for students to probe, then the big spaces should be useful.
It is a learning tool for me making boards (and getting back into electrical engineering). I kept everything spaced out for my own learning purposes and ease of tracing/id’ing parts of the circuit. My next radio receiver (FM, superhet), will be much tighter.
Thanks for all the tips, I very much appreciate them.
