That was a bit of late night desperation. Let's see if I can rephrase the question: If I look at the 'panelization' options, they are all focused on repeating a single board multiple times. When I've experimented with this, there have been gaps added between each board (with tabs/mouse bites etc.). I would like to replicate the tabs/mouse-bites approach, but using two designs like the picture above (whilst the boards can be split, the proximity of the slot in the right hand board means that there is a weak point prone to breaking unless I use a knife to deepen the V-cut. If I sent a PCB design like this (shaped like a 'H'), how many designs should I declare in the JLCPCB order form? 1, 2 or 3? And is this classed as 'panelized by user'?  Obviously this PCB is slightly wider than the pair in my original post, but it would be massively easier to split! I've taken the original approach on 3 designs, and it's only the third one where I've had an issue with separating the boards… the Any advice gratefully received! I'm sure I'm not the only person doing this.

Hello, I want to do something similar, but I don't understand how you divided the PCB in two. Did you just make a rectangle twice the size of one PCB and then added a line in the middle on the board outline layer? And did you manage to find a better solution to make it easier to split? Thanks.

I'd actually go with two separate PCBs. I've also done projects where I used a PCB as a frontpanel and I've always used separate PCBs. Some benefits: * clean and precise routed edges on all sides of the pcb * ability to use different solder-mask color / pcb thickness * easier (re)order of new circuit panels without frontpanel (or vice versa) And except from maybe a slightly bigger price, I don't see a downside at all. Btw: I've seen you have an LED on your PCB shining through the frontpanel substrate. You could add solid copper fill on your bottom layer of the frontpanel and just exclude the spot above the LED. I'd also remove soldermask there. This makes the LED more visible and would give it a sharper outline.
