<div>The following is a user-submitted list of PCB manufacturers. Your results may vary.<br />
<br />
: ''This page lists "board houses" that take your custom PCB layout file and convert it to a custom printed circuit board (PCB) (ready for the next step: "assembly" adding parts). For "standard" prototyping PCBs, see [[stripboard]] and other [[techniques]].''<br />
<br />
The Ladyada PCB Cost Comparison Calculator[http://www.ladyada.net/library/pcb/costcalc.html] is a quick way to compare the (very roughly estimated) price of your board at many of the following fabs.<br />
<br />
''(FIXME: briefly mention the most relevant "capabilities": "preferred" and "minimum" trace width / spacing / via hole size / via pad diameter.''<br />
''Link directly to the manufacturer's "capability page" so readers can confirm these numbers for themselves.''<br />
''Boards that push the limit of manufacturability cost more than robustly designed boards that use preferred sizes.) For more details, see [[Submitting PCB's for fabrication]].)''<br />
<br />
A few of these board houses do some automated DRC or manual checking (or both) before fabbing your board.<br />
If they find any issues, they email those issues to you and put the board on hold -- which typically delays the board a day or two.<br />
However, most people consider this a good thing -- they would rather have a board a day or two later than the quoted turn time, rather than a definitely nonfunctional board immediately.<br />

preferred:<br />
15 mils min drill hole diameter<br />
6 mil trace/space<br />

Can go to 10 mil drill and 5 mil trace/space and still get "no touch" service (very modest price increase)<br />
Also can do outlines with up to 16 edges.<br />
<br />
Has free BetterDFM service to check a design before fabbing.<br />
<br />
Has a "will-call" pickup option if you live in the SF Bay area. This is nice because it cuts a day or two off your overall fab time<br />
<br />
One disadvantage of Sierra "no-touch" is that they have a surcharge if you go over their hole density limit. (haven't seen this with other fabs)<br />
if you have more than 50 holes per square inch - their automated system doesn't let you place the order - you have to have someone manually add a $10 surcharge per board to continue.<br />

Free proprietary schematic and layout software, used for all board services (like PCB123). Simplifies the process of getting a board done and out, by vertically integrating the design and production flow. Fewer options and less power, but fewer ways to screw up.<br />
*Good deal on small prototypes: Mini-Board Service (3 identical boards, 2.5" X 3.8", doublesided, plated through, no silkscreen or soldermask) is priced well at $51 total, plus $10 shipping. Orders placed by 2PM ET ship the next business day by 2nd Day Air. <br />
*Capabilities(inches) [http://www.expresspcb.com/ExpressPCBHtm/SpecsProduction.htm Production]: Minimum trace width: 0.006". Minimum clearance: 0.006", preferred 0.010" . Perimeter clearance: 0.015", suggested 0.025". Holes - 23 sizes: 0.014"(via only), 0.020" - 0.251". Minimum Hole Spacing: 0.021" between edges. Vias/holes: 0.031"/0.014" -0.115"/0.052" . Pads/holes(round/square): 0.041"/.020" - 0.450"/0.251" . SMT: 0.010"x.070" - 0.420"x0.420" BGA: 0.012" - 0.020" . <br />
*Software features: SCH netchecks. PCB imports PADS netlists, and illuminates nets nodes to assist in connection. Built-in updated price quotes for all offered board services. Copy to clipboard available for schematic & silkscreen+pads(layers must be screen-captured.) Pretty good selection of components, pads, symbols, for free. <br />
*Notes: No Gerber support. Primitive single-level undo/redo. No PCB footprint selection/placement wizard from SCH info. No autorouting. SCH generates BOM, but PCB can't back-annotate (frustrating because most PCB footprints have Digikey part#s.) No net-based vendor integration. No scripting or plugins integration. Not enough keyboard shortcuts, uneditable.<br />
*Review: The company is responsive and responsible. The Mini-Board service is addictively cheap and fast, and the other proto and production services are good, if not the cheapest option. Board quality is high; fine traces held up perfectly. The software is stable and simple, but tedious work for high parts-count or high-density boards. <br />
*Conclusion: The sweet spot for ExpressPCB is sparse, simple, quickly-designed boards, at low and very high quantities. At any other density or complexity, might as well learn and use Eagle or KiCAD.<br />

* Green solder mask, white silkscreen (one side)<br />
* Free Step & repeat, V-scoring<br />
* As many of your design as will fit into 1000 CM Sq for $99, including shipping to North America<br />
<br />
All specs may be dropped down to the below ratings, for an additional fee -- this can end up costing more than the "normal" panel itself!<br />
