content: Hi everyone,I am sure that there is a topic like this, but I can not find it. Because of that, I start a new one. I am sorry for that.I have a design that has 2X2cm dimensions. I want to produce a PCB that has 10X10cm dimensions and has 25 of my design. What should I do?In JLCPCB, there are three options.1. Single PCBWhat if I create schematic and PCB has 10X10cm dimensions and has 25 of my design and I draw silkscreen lines to separate same design. Does it work? Do JLCPCB V-Cut?2. Panel by CustomerWhat if I create schematic and PCB has 2X2cm dimensions and it is my own design. Then I choose Panel By Customer, and set column and row 5. Does it work? Do JLCPCB V-Cut?3.Panel by JLCPCBI do not want to use this option. Because it cost more and I can not afford it.Thank you for your answers. I want to say that I am sorry for my grammer. I am not good at languages.Note: I added a jpg file. I mean that when I say V-Cut. Maybe it does not call V-Cut.

content: Agree with fellow Canadian @Zoli as per above.You want SINGLE PCB + YOU supply a single file with the full look of the panel shape and this file will contain the V-cut / V-scoring lines.Keep in mind that the machines do the work, they want this job to be fully automated so it is cheap for them to produce and cheap for you to buy.We have done the same with assorted project with success - similar to @Zoli.Test out your panelization layout and post here if you need help. Can ask our PCB designer to offer pointers if required but there are many online gerber viewers - including @ JLCPCB that will show you the gory details of the PCB panel.Summary: Keep it simple for them, it will be cheap and the job will get done.

content: When I needed to do this I did my own panelisation, put routing around most of the edge of the sub-PCBs (in KiCad's outline layer) and put V-Cuts in the outline layer with an annotation next to each one that it was a V-cut:and this is what I got back from JLCPCB:

content: Interesting that they made this. Last time I did panels with JLC they had the requirement of a minimum distance between V-cut lines, which was about 20mm or so. I had a board similar to yours with just a SOIC between two rows of pads and it was not wide enough, so I used mousebytes in one direction and V-cuts in the other. It serms they either got rid of that restriction or they simply made yours anyways
