A. There is no extra cost for identical design panelization.
ie. Choose "Different Design 1" means there is only one design in your PCB Gerber file. So if you want to separate multiple boards with V-cut or milled slots, please make sure each sub-board is the same and less than 42pcs sub-boards per panel.
If you want to use v-cut, please following those rules:
1) The entire panel size should be ≥ 7cm*7cm, ≤ 38cm*38cm.
2) The sub-board size should be ≥ 8mm*8mm.
※Please note if the sub-board size is ≤ 15mm*15mm, we will inform you to pay USD16 for the processing fee.
3) V-cut line can only be a straight line.
4) V-cut line can only be cut from edge to the edge.
5) V-cut line must be zero pitch between sub-boards.
6）The minimum distance between circuit wire and the v-cut line as ≥ 0.4mm.
7) The thickness of the board must be ≥1.0mm.
B. Different PCB panelization.
Choose "Panelized PCBs" option, ie. 2 panelization= 2 designs, Maximum is 9 designs.
Panelization allows you to put sub-boards on one panel.
For example, we have three PCBs need to be made on one panel.
This is an INCORRECT EXAMPLE, Please DO NOT draw the outline like the pictures below.
Problem: There are 4 outlines, we have no idea which outlines we should follow.
Problem: The width of connections is too small and too long.
Problem: Width of a panel is smaller than 55mm.
To make the v-cutting line, the width should be more than 55mm, the length should be more than 70mm.
Problem: The v-cutting line should be straight and edge to edge.
Add margin to hold the sub-boards, the width of margin should be more than 3mm.
Add connections and stamp holes to separate the board.
Add slots to separate the board.
If you don't want to pay extra money for the panelize fee. You can make the outline like this and cut the board by yourself.
C. No panelization.
