Always nice to watch someone design a PCB ! I think you should use a ground plane on a board this simple, if not for electrical stability then for using less etchant, the big manufacturers are still a bit secretive about how they dispose of or reclaim saturated etchant, and this is a growing problem nowadays due to our ability to just pop a few components on a board and get it made for pence, the price is being paid somewhere, but Kudos to you ! very brave doing this live (sorta!)...cheers.
Marking a pin as having no connection is done by putting an X on it, bottom row of Wiring Tools. Add top and bottom copper areas, top +3.3 volts, bottom ground, then you only have to route signals, the dotted copper area tool. The BOM file is easy to edit in Excel to get everything right. Panel the pcb by stamp hole to get around the size issue, add a border so that the order number gets put on it rather than on your board and DO NOT check any panel options on the order page ! The low cost postage options are hidden, you need to "show more" to find them.
24:00 You have the option of getting all the boards populated with SMD components or just 2. I guess if you wanted just two assembled for testing before committing to all three, you could assemble the rest yourself later. This is a prototyping service after all 😉
To get round the size problem, double the design in one pcb and place a track down the length between the two boards. Then convert the track to a slot.
@22m22s: You could also siamese two board together, making pairs of boards to be separated later. I assume that they can score or router the boards to make bending them apart easier for you. Cheers !!
Yep. But the distinction is that if the explicit "paneling" option fails to satisfy their minimum size requirements (because they fixate on the base PCB size), then by 'silently' doubling-up the entire design it would force the project size to be taken as doubled size. Just an option in case needed. It depends on how they enforce their minimum size requirements. Cheers.
@@JxH Minimum size between V scores = 20mm, minimum size for the V score machine = 70mm x 70mm. Panel by V score not permited for SMD assembley. Borders can be added. The easy way to do a sub 20mm pcb is to panel by Stamp Hole as there is no paneling charge for sub 100 x 100.
When you had to widen the board to meet JLCPCB size requirements then you could've just dragged one side out, one cut then as opposed to two if you wish to pursue the cutting afterwards. Too late now I know ......
@14m30s: Me screaming at my screen that the blue trace now has a clear run on the other (red) layer: Around H3, down and then right, through the empty wide gap past C2, C4, and so on. SINGLE LAYER !!!
Minimum dimension for V score is 20mm, and minimum size for the pcb to suit the V score machine is 70mm x 70mm. Panel by Stamp Hole is the correct solution :)
Hello Julian. Thank you so much for the video. I am sorry if my question is stupid. But i am newbie in electronics. I wonder if that 4x2 connector on the right is two sided plated. I mean if the smd components are on top side and routed to that connector on top, can i still solder pins from bottom side? I mean does the holes work like via?

@@zippy7262 With EasyEDA its simple, Tools > Panelize, Select Stamp Hole, a special tool can be bought to cut these, so you set the spacing to suite the cutter you have :)
I've been designing a "supercomputer" in the vein of the one BigClive made for his live stream channel, and it never occurred to me that I could just get them so solder all those tiny SMD resistors for me, which would save a lot of effort! I'd still have to solder the blinkin' LEDs, but that should be much easier than all those tiny resistors. Unfortunately I've been designing it in Kicad, which might make the process a lot more complex, since I'll need to figure out how to make the BOM and CPL files myself.
The shipping is available for much less, if a standard delivery service is selected. The component fitting is more ridiculous. £17 for £1 worth of components, which would take just minutes to fit by hand.

Thanks Andy - I guessed it had to be there somewhere :)

Thanks for showing all the fiddly bits, I learned a lot! And thanks to the smart commenters here with their good suggestions.
Glad it was helpful!

Just panel by stamp hole :)
Thanks Julian. I was just looking to get started with Easy EDA and these videos were helpful.
Great to hear! Good timing then.
A few other comments might have touched on this but panelizing the board would have preserved the esthetic. Great video nonetheless.
I love the suprise get coupon, on a sponsered video HA HA!!:-)

Thats called paneling them

Why did you not make the back a ground plain, and why not panelise?? and get more boards??

He should have just paneled it
Always worth watching : )
Just think how much you would have saved if you put all the components on to one PCB.
Indeed.
Nice video. Very informative.

You could have added a breakaway tab with a score line for the width for the assembly. Then you would just snap the piece off.
Minimum dimension for V score is 20mm, and minimum size for the pcb to suit the V score machine is 70mm x 70mm. Panel by Stamp Hole is the correct solution :)
What about route and retain breakaway tab?
@@hectorbacchus Why bother, you are paying for 100mm x100mm, just panel by stamp hole (slot & mouse bites )
Why not make the back of the board a ground plane entirely rather than just running one ground track on it?
Exactly, ground on the back and power on the front, then you only need to route signals :)

Still could have v-scored the board to the size you wanted, right? Bit late now, like
At 23:27 it says "Panels with V-cut can not be made with SMT assembly, please panelize PCBs with stamp holes."
@@DaedalusYoung So it does! I wonder why that is?

@@steverpcb Thanks Steve! I never panelled like that before, so I'll have a play with that.

Worth the effort in the long run, think of the future !
I had them do the resistors on my supercomputers and in black :)
Big Clive has asked me to post one to him :)
Those shipping charges are ridiculous.
You can get cheaper shipping, I pay £5.48, but it takes 10 days or so to get here. 5 of which are spent in a Royal Mail warehouse at Heathrow.
@@DaedalusYoung 10 whole days? I'm waiting like 1 - 1,5 months here in Greece...

Julian, watching you lay out that PCB was painful. Have you got an aversion to vias ?
