I,ve used itead a number of times now since Crossroads introduced them to me a year or so ago. I,ve not had them deliver to the UK in under 3 weeks, but thats my choice - the price and quality are good for me.
However I have a design where I need 25mm x 50mm. I already ordered the same design and doubled them up on a 50 x 50mm pcb, but I,m struggling to cut them in half with the tools (or lack of) I have at home - 1.6mm is surprisingly thick when you try and cut it! So if I ordered from itead a 25mm x 50mm design, but under the 50mm x 50mm ordering code, would I received just 10 pcb's and effectively waste half the order, or would they supply twice as much, ie 20 pcbs?

Thanks,
Texy

Yes to itead or seeed. They don't charge per area but charge per predefined area. It is wasting money and material but that is the only way they can offer low price. If you make more than 100 boards, you should email them to see if they are open to negotiate price down. Everyone fits within a predefind box so they can easily and quickly fill up a large board for printing. Hope if you do come to negotiating, your experince is better than mine.

No, you would get 10 PCBs. If you want to get 20, you would either double-up or add another 10 PCBs to your order. If you want to cut them, invest in a scroll saw or a dremel. I just cut some of mine this past weekend and had no problem with the scroll saw.

Visit your local hardware store and pick up a hacksaw, works great for cutting in half also.
They might inquire with you about the duplicate design on the board, but as along as you're not adding a row of holes or similar down the middle they'll likely make it for you.

Yes, you would "waste" that area.

A hacksaw actually cuts PCBs just fine, if you cut along the flat area. If you try to cut on the edge, it doesn't work very well.
Just put the PCB on a corner of a workbench, lay the hacksaw flat across the line you want to cut, and saw; takes only a minute!
