"International Traffic in Arms Regulations" (ITAR) govern the export of weapons and weapons-related technology from the United States. If your board design data is ITAR-controlled, please inform us of that when you place your order. For basic information on ITAR, go to http://en.wikipedia.org/wiki/ITAR. For detailed information on ITAR, go to http://pmddtc.state.gov/.
+-How do I keep my order from going "CAM Hold"
There are multiple reasons that an order gets placed on hold, such as corrupt files, omitted information, or missing connections. To avoid having your order placed on hold, please review the "How to Avoid CAM Hold" section, Click Here.
+-Do you have any cancellation fees?
A prorated cancellation fee will be charged for cancelled orders depending on fabrication status at the time of cancellation. $33 Each, $66 Each, and Barebones orders are subject to 100% cancellation fee. Please contact your Salesperson immediately and follow up with a fax or e-mail to confirm and provide written record for any verbal cancellation.
+-Why can't I get a quote for a dimension less than .5"?
Our matrix is set to 0.5", enter 0.5" as the dimensional unit for quoting only. If you have a dimension less than 0.5", enter 0.5" as the dimension or call your Sales Person to get a quote. If you place an order from this quote, be sure to put the actual dimensions in the COMMENTS section of the order. Your printed circuit board will be fabricated to your actual dimensions. There may be additional costs associated with your smaller dimensions.
+-Where should I send my files to get a printed circuit board quote or place an order?
+-Will you allow me to put several part numbers together and run as one printed circuit board offer?
You are welcome to panelize circuit boards together to make one order. To do this, all your files must come to us pre-panelized. However, we cannot rout these into into individual boards. They will be shipped to you as a tab routed array or as an un-routed array as you specify on full spec orders. Multiple parts or step and repeat of a single design are available for the $33 Each and $66 Each Specials for an additional charge of $50; however, individual or tab routing of the multiple images is not included in this service.
+-Under what conditions will Advanced Circuits change my requested method of shipment?
Our intent is to always ship via the carrier you choose and to use your shipping account number if provided; however, all the carriers (UPS, FedEX, and DHL) have different pickup schedules during the day and evening. Our last pickup is provided by UPS. If your order is ready for pickup after the final pickup time by your requested carrier we will change the carrier, as we assume that it is more important to you that you receive your order on time as expected rather than what carrier is used. In doing so, we will not be able to use your shipping account number. We will ship it on our account and add the shipping charges to your invoice. If you request a change to this policy, we will be glad to hold your order until the following day's scheduled pickup by your preferred carrier.
+-How do you define your "Standard Spec shipped on Time or Free Policy"?
a. We guarantee shipment for our Standard Spec PCBs within our Standard Spec turn times which is 3 days for double-sided and 5 days for multilayers. If we ship after these time intervals, we will upgrade the method of shipment at our expense if necessary to ensure ontime arrival to customer. If we cannot upgrade the shipping, we will, when requested by customer, provide a credit to offset the cost of the boards. For orders having partial shipments, only those boards shipped "late" qualify for the "on time or Free" policy. Excludes any other services, goods, or offerings.
b. For Standard Spec PCBs placed with expedited turn times less than these standard times and shipped late, an expedite cost credit for each day beyond the order ship date will be available to the customer up to the time when the standard turntime is exceeded. If the applicable standard turn time is exceeded, then the "Free" aspect of this policy will apply. Exceptions to policy if shipment upgrades can be made and/or partial shipments are detailed above. Excludes any other services, goods, or offerings.
+-What happens if UPS, FedEX, or DHL is late in delivering my order?
We work very hard to make sure all your PCB orders get shipped on time. There are occasions, however, when the freight carriers have delays and/or make shipment errors. We regret when this happens but we cannot be responsible for delays by these carriers.
+-Who is responsible for import fees and custom charges on international order (outside the U.S.)?
All International customers are responsible for their own custom charges and import fees on all orders.
+-How do you define your turn and cut off times?
The day order is processed and confirmed to customer is counted as Day 0. 1-day turn orders, for example, ship next business day. Same-Day orders ship same day if received and confirmed to customer NLT 8:15 AM MST M-F. "Weekend Wonder" Same Day orders received and processed on Friday (NLT 3:00 PM MST for 2-layer, and 12:00 PM MST for multi-layers) will be shipped on Saturday for Monday delivery.
Immersion Gold (ENIG) Multilayer orders (3 – 8 layers) placed for a 1-day turn must be received NLT 12:00 PM MST Monday – Friday. Immersion Gold (ENIG) orders (0-2 layers) placed for a 1-day turn must be received NLT 3:00 PM MST Monday – Friday.
+-If I receive a price using your online quote matrix, does that guarantee turntimes & quantities?
If an order is placed online or by any other means, it is not guaranteed to be accepted by Advanced Circuits until it passes our engineering review and customer’s receivables account is in good standing.
Online price quotation does not guarantee total order quantity and turntimes. All order quantities and turntimes are subject to production capacity review.
+-Do you schedule out shipments?
We will schedule out shipments over a 6-month period; however, the order will be manufactured at the discretion of Advanced Circuits to maximize Custom Spec capabilities and cost efficiencies. If for any reason this order is cancelled at any time prior to the final scheduled shipment, any or all of the completed order will be subject to a cancellation fee which may be up to 100% depending on the manufacturing status at the time of cancellation. Customer is liable for all completed product quantities.
+-Will RoHS Lead-Free Custom Spec Boards be marked with lead-free symbol?
RoHS compliant lead-free Custom Spec boards will be marked with a lead-free symbol if requested by customer. If not specifically indicated on fab drawing or requested in separate document, the lead free symbol will not be added. No symbols of any kind are added to protos other than the work order number for fabrication identification purposes.
+-What is Advanced Circuits Warranty on PCBs?
ADVANCED CIRCUITS 90 DAY LIMITED WARRANTY
This limited warranty is governed by and construed under the laws of the State of Colorado.Advanced Circuits warrants its bare boards against defects in materials and workmanship under normal use for a period of 90 days from date of shipment ("Warranty Period").

+-Does Advanced Circuits bevel gold fingers?
Yes. We do bevel gold fingers unless otherwise specified. We do NOT bevel solder fingers unless specified by customer.
+-What is your standard bevel on a printed circuit board?
Our standard bevel is 30 degrees leaving a .030" edge ( /-.005") on a .062" board.
Optional bevels are as follows:
45 degrees leaving .025" edge ( /-.005")
20 degrees leaving .071" edge ( /-.005")
+-What is tab route?
A tab route is used to create arrays, often called "route and retain". The customer can place more than one board (same or different design) up in a given area in an array or panelized configuration. This is typically for the convenience of the customer or for assembly requirements that utilize pick and place machines to load components. The PCB's are then separated by breaking or cutting the tabs. Tabs are usually 0.100" in width and are placed with at least 1 on each side of the boards.
+-What does "scoring" mean?
This is a "v" groove cut into the top and bottom surface of an array of multiple PCB's or between a board and rails to be removed after assembly. The cut is usually 1/3 top, 1/3 bottom, leaving 1/3 uncut in the middle. This process is used when removing the tabs of a tab route is not a viable option, this does result in a less smooth finished board edge. The boards are typically set up side by side and end to end with the edges adjacent to each other. After assembly the boards are broken or snapped apart.
+-Can you handle Controlled Impedance requirements?
Yes. Call your salesperson for more info.
+-Can you process my dielectric requirements?
No problem. We will run this as a custom order. Be sure to send us your core and stackup details.
+-What is the difference between a prototype pcb (Standard Spec) and production pcb (Custom Spec)?
The difference between proto & production is not a quantity or turntime issue, but rather has to do with the range of specs covered. Click here for a complete list of these specifications.
+-What files do you need to manufacture my printed circuit board?
We require gerber files (274X or 274D with an aperture list), an excellon drill file, and a drill tool list (may be included in excellon drill file). We can use other formats such as ODB or AutoCAD dxf to create gerbers for you. Please send any non-gerber formats to [email protected] for review.
+-When do I pay a tooling NRE fee for my printed circuit board?
You will only pay a Tooling charge if you go directly to Production (Custom Spec) without having ordered a Proto (Standard Spec) as a first step. We do not charge Tooling for Protos (Standard Spec) and neither do we charge Tooling if the proto (Standard Spec) is reordered for Production (Standard Spec).
+-If I only have a minor change in my design, do you charge Tooling NRE?
When we make any change to your printed circuit board, we assign it completely new tooling. This helps prevent old artwork or cnc programming from being used. Even a minor change will require the same process as new files, so a tooling charge may apply. Please contact your salesperson for details.
+-What is Test NRE?
The Test NRE is a one-time "non recurring expense" for electrical test. This charge is optional but when paid, all circuit boards will be tested each and every time that part number and revision is ordered without additional charge.
+-What core thicknesses does Advanced Circuits use for multi-layer circuit boards?
.003", .004", .005", .008", .010", .014", .021", .028", .039", .059", .093" cores. Please contact your Advanced Circuits representative as other thicknesses may also be available.
+-What is the thickest printed circuit board you can process?
+-What is the thinnest printed circuit board you can process?
.020" if ordered with solder HAL plating finish. Thinner if other plating options are used. Contact your salesperson for details.
+-What is the largest pcb Advanced Circuits can fabricate?
37" x 120"
+-What do you need if I want my pcb panelized in array format?
We recommend you send us your complete array pre-panelized. This allows you to set up the array exactly the way you want it. If you need us to set up your array, please be aware that additional engineering time may be billed.
+-What file generating software would you recommend?
