PCB Panel Design Question

Srijal97:
Hello all,

I'm working on creating really tiny PCBs (11x10mm) and I wanted SMD pins on the edges of the PCB like the ESP-12 module has. How does one go about designing a PCB like that in the design software(I use EAGLE), and how exactly do you place the order for such PCBs? From what I've read, you have to create a PCB panel and then break them once is manufactured, but how do you add the break marks, plated holes and copper pads on the edges in the design software and instruct the manufacturer what I expect?

I've attached a sketch I made showing what I wanted to do. Thank you for your time!

If its like in my avatar, you just create the wholes(must be plated) then you solder pins manually. It can be done by the manufacturer, but I don't know if they offer it everywhere.
Rerouter:
They are called castellations, and the sides are plated. generally the areas with castellations are fully routed for the plating process. but in this case the best answer will come from the manufacturer.
Richard Crowley:
The proper term is "castellated holes".
Some PCB manufacturers offer the feature, but you can also "DIY" after they are made.
My impression is that the extra cost may be prohibitive for small hobby quantities(?)

What you call break marks are V-score lines. Usually you need to draw them as lines in board outline layer.

Castellated holes can be done either with milling or with V-scoring as shown in your sketch. Ask your manufacturer what is prefered method is.

Plated holes and copper pads are just basic THT pads, nothing special. You may add a via in this pad to increase mechanical stability.
