Min. Edge Rails limitation

Hello, folks. On this page [https://jlcpcb.com/capabilities/Capabilities](https://jlcpcb.com/capabilities/Capabilities) the "Min. Edge Rails" is said to be "3 mm". Is it really true that I cannot order a PCB without edge rails, or with very narrow ones? My whole board is 7 mm wide, and the maximum trace width that I can afford is 14 mil. Thanks.

The edge rails are only for if you order panelised PCBs. The edge rails are not part of the PCB that you are designing: ![V-cut-v-groove.png](https://jlcpcb.com/uploadfiles/image/20180517/1526540223333020334.png) ![Panelization-with-space.png](https://jlcpcb.com/uploadfiles/image/20180517/1526540173973072783.png) You do however, have to note the minimum clearances between traces and the board edges (which depend on whether the PCBs are routed or V-cut): ![image.png](//image.easyeda.com/pullimage/VkqCEO1wSvIhc2gXtWwpdQbMph6gfRbW7Pk1zAhW.png)

@andyfierman Ahhh that's what it is... I thought those were GND or Vcc traces. Thanks, Endy.

@andyfierman Until now, as long as I understood from all EasyEDA documentation and forum topics, position holes and fiducial marks are needed only for panelised boards which will be automatically assembled. Am I correct ? What about edge rails ? Are they a requirement for any panelised PCBs production, independently of their hereafter manual or automatic assembling? Thanks in advance,

@miggarc, Those are questions to ask as a new topic in the JLCPCB category.
