Hi, I made a little project and it consists of 4 boards with same size. Every board has different stuff on it and I wondered if the way I did it will work with JLCPCB. What I did was making a bigger board (7cm by 7cm) and placing two board layout lines crossing at the center, thus making it into 4 3.5cm by 3.5cm boards. Or should I use mechanical layer to place these lines?
Brand new interactions and interfaces. 
Easy to use and quick to get started.
