What files do you need to manufacture my US Quickturn PCBs?
The following files need to be compressed into one ZIP file and uploaded through the US Quickturn PCBs web site at order placement. Our web application will only accept one ZIP file per order. Your file set needs to be complete with the following data:
1. Gerber files in 274X or 274D formats. (274D format will require an aperture list or environment file)
2. Excellon2 NC drill file.
3. Drill tool list specifying finished hole sizes, hole quantities, and plated/non-plated holes.
ViewMate Users Can Send a *.bin file from ViewMate Deluxe/Pro or a Smart DFM *.EZQ file from any ViewMate version.
You may download ViewMate for free to check your files and to send Smart DFM *.EZQ file for PCB orders.
If you need assistance creating files, downloading or using the software, please contact us!
How do I send my files?
You will be prompted to upload your files through the web site during order placement. Your files are encrypted and maintained in our secure database.
What is the US QuickTurn PCBs manufacturing policy?
1. All orders must conform to our technical file setup. See technical file setup FAQs.
2. Orders are not guaranteed to be accepted by US Quickturn PCBs until files pass our engineering review.
3. Boards will be manufactured per supplied customer files.
4. We will notify you if there are any noticable errors that may cause "show stoppers" in manufacturing of your board.
5. All files will be retained for three months.
6. Prices are subject to change at any time.
7. Orders can be shipped anywhere using FedEx/UPS.
Routing
Default rout tool diameter is 0.0625".
All features are cut out using this tool if possible (both internal features and the board outline).
Do PC Boards UL marking?
By default we add a UL marking to the bottom copper layer:
We add a Date Code, a 3 digit order fragment and a Serial Number to the bottom silk screen layer:

What is the minimum trace width allowed?
The minimum traces width is 0.005" (6 mils).
What is the minimum spacing between traces to copper lands?
The minimum gap between traces and copper lands is 0.005" (6 mils).
What is the minimum annular ring on vias?
The minimum annular ring on vias is 0.006" (6 mils) each side of the hole. The pad must be large enough to tent over the hole otherwise you may lose the metal in the hole during outer layer etching resulting in plating voids.
What is the closest copper to edge of board?
The closest copper trace and land fills to edge of PC board is 0.010" (10 mils). If the copper runs closer to the edge it may be exposed during board rout.
Are the boards electrically tested?
All multi-layer (4, 6, 8 and 10 layer) boards come electrically tested as part of the service. Two-layer boards are not tested.
Can you handle controlled impedance requirements?
No. This feature is not available through the US Quickturn PCBs service. However, you may submit a Custom_RFQ for complete PC board manufacturing needs.
To what acceptability standards do you build?
PCBs are built to IPC-A-6011/6012 latest revision Class 2 with inspection based on IPC-A-600 latest revision.
What is OSP finish?
OSP (Organic Solderability Preservative) is a thin organic coating deposited on the exposed copper. The coating preserves the solderability of the copper surface, while allowing it to be easily soldered without the need for removal. Excellent solderability is maintained through 3 to 5 I.R. soldering cycles.
