Can you supply prototype sample boards free of charge?

Yes, we can provide prototype sample boards (1-2 PCs) free of charge if you order more than 300 pieces. You only pay for the shipping fee for the sample. We will make production boards after your approval.

If the design is changed after the prototype sample, we will have to charge at the prototype cost.

Do you charge extra for tooling, photo and E-test, etc. ?

We do not charge tooling and photo fee for prototype boards. There is a fee for setting up for production boards. This charge will be credited back to you when the accumulated orders are over a certain amount. We do not charge test fee for production order.  We can also provide electric contact test for prototype boards with Flying Probe system at low cost.

If I order initial small quantity first and order large quantity later on, do I still pay setup fee?

Setup fee and test setup fee are one-time charge. These are only applicable to new orders and will be waived when you repeat the order.

What kinds of file formats do you accept?

We can process Gerber RS-274X, 274D, Eagle and AutoCAD's DXF, DWG formats.

What type of Bill of Material (BOM) file do you accept?

We prefer MS Excel format, but other formats are also acceptable. Please see a sample BOM file here: Sample-Bill-of-Materials-BOM.

an you do routing for me?

We route any quantity of PCB which has more than 2 layers, including double layers.

What is your standard drilling size?

We can drill any of the size for prototype and production boards start from 0.1mm, 0.05mm,  0.3mm, 0.35mm, 0.4mm, 0.45mm. Normal drilling size starts from 0.35mm.

Do you keep solder mask web on all the time?

Solder mask web is the small lines of solder mask placed between surface mount pads to reduce solder bridging during assembly. Solder mask webs have a minimum width that can be reliably exposed and still bond to the board. In our assembly process, this minimum width is 0.2mm. Solder mask web thinner than 0.2mm may be removed during assembly. If you really need to keep the solder mask, please contact us.

Our business and sales offices are closed on weekends and on all major IRAN. holidays, but our manufacturing facility operates 24 hours a day. Through our website, Advanced Circuits' customers can get quotes, place and track orders, and have their designs checked 24 hours a day, seven days a week at www.FreeDFM.com.

What does CNC Rout points mean?

Each corner or ""turn"" on your pcb is a rout point . Each radius is three points.

What is tab route?

A tab route is used to create arrays. The customer can place more than one board (same or different design) up in a given area in an array. This is typically for the convenience of the customer or for assembly requirements. 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 Production order. Be sure to send us your core and stackup details.

What is the difference between a prototype pcb (Standard Spec) and production pcb ?

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 is Test NRE?

The Test NRE is a one-time  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.

Are your proto's built differently than production?

No. Our prototypes (Standard Spec) use the same premier production (Custom Spec) processes as our production (Custom Spec) circuit boards.

Are you UL ""Underwriters Laboratory"" approved?

Yes, you can use the following web link to access our UL registration. Underwriters Laboratory

Are you MIL SPEC 55110 approved?

NO. However, you can refers Prototype (Standard Spec) with us because we use the same materials, specifications, and processes.

To what acceptability standards do you build?

IPC-A-6011/6012 latest revision with inspection based on IPC-A-600 latest revision: Class 2 Prototypes (Standard Spec) and Class 2 Production (Custom Spec).

What CAM software do you use?

We use Gerbtool to edit and view.

Can you build RF applications?

Yes. We stock several RF materials such as Rogers 4000, Teflon, Duroid, and Polymide. All of the pricing is subject to change at any time without notice. We reserve the right to refuse any order at any time.
