How to get a bare bones quote and order ?

I have a simple 2 layer board.
Board is rendered (schematic/layout) in PCB123 V5
It is 3 in x 4.7 in
No need for solder mask.
No need for silk screen.

It is a "work in progress" so I really don't want to pay $160 to $190 for 1 board since I will probably have several iterations before it is perfect.

I entered my board info into the following web page:

Cu conductor thickness


I am looking for a PCB for a special application. The board is meant to be used in an extreme cryogenic environment and I need the copper lines of the thinnest possible cross-section to limit their heat conductivity.

How thick is the copper conductor layer you use in your board? Are there different thicknesses available? If so, what is the smallest thickness you can offer? Do you offer any other metals for the conductor ...

Toe to Toe Spacing/Solder Mask webbing

I want to push the component density limit. I'd like to place two 0402 components next to each other, with a toe to toe spacing (pad edge to pad edge) of 7 mils, which would provide 4mils solder mask webbing between the two pads. Any concern of solder bridging or insufficient solder? Is 4 mils enough SM webbing to isolate the two pads and solder paste?

Layout for panelization

Hello! I have several small board designs I want to put on a single panel that I will cut apart. Do I need to produce one file with all the circuit designs in it or can I submit the individual circuit designs to be placed on a single larger board? I am Using Eagle to lay out the boards. Thanks!
