# PCB Panelization Impact

What is the impact on a PCB design if it is panelized? I received a message from a PCB manufacturer:

In your order, the quantity of boards is large and the boards are quite small. Can we panelize the boards for easier handling? If no, will cost an extra $32USD additional While I wouldn't mind saving$32, I'm also worried the panelization will leave ragged marks on the PCB edges. Is that the case?

• It depends on how they are cut - is the manufacturer offering to "individualize" them for you? The manufactured PCBs that I have had panelized were cut apart by me on a precision band saw and came out perfect, so if you have the tools it can easily be done. – Tyler Stone Jul 4 at 4:21
• That's all the manufacturer said. The design has no straight edges -- all edges are curved. – Kayvon Jul 4 at 4:23
• If all edges are curved, then V-grooves are out of the question. It will probably be tab routed which can leave a mark where the tab is broken. Apparently, panelization is an art with lots of different factors and consequences such as not stressing populated components when de-panelizing after automated assembly, not flexing too much but being rigid enough for assembly. I think you can also get routed de-panelizing which would leave a smooth edge. – DKNguyen Jul 4 at 4:25
• That's what I suspected. Thank you for the confirmation. – Kayvon Jul 4 at 4:27
• @Kayvon Talk with the board house about their depanelizing options. There is a type of tab routing where the tab is not meant to be broken or sheared, but is meant to be routed. This would leave a clean edge (i.e. the curves your the rest of your PCB are made using a router). – DKNguyen Jul 4 at 4:27
