Frequently asked Questions ( FAQ )

What does PCB1STOP do? What are your PCB/FPC and PCB Assembly Cappabilities?

PCB1STOP.com, an online platform of Bay Circuits Inc, provides the best value in PCB and FPC quick-turn prototype to mid-volume production, and PCB Assembly;  We also make SMT stencils and manufacture custom-made membrane switches.

We partner with well-regarded ISO 9001:2008 certified PCB and FPC manufacturers and Assemblers to provide you exceptional quality at low prices. While we do most of our business though our website, we also provide custom quotes for PCB and FPC with sophisticated requirements that do not meet our online standard specs, and production quantities through our partner PCB manufacturers and Assembly companies in Asia.

Please tell me more about your Standard PCB prototypes.

Our Standard PCBs are 2 to 6 layer PCBs with Solder Mask and Silkscreen, made to your specifications at amazingly low prices.

Briefly, the PCB specs for standard process are: FR4 material, 0.062 inches thick (+/- 10% tolerance), 0.006 inches (6 mils) minimum trace/space, and 8 mils minimum hole size. We include Solder Mask and Silkscreen in the price. And we waive all tooling charges. The turn time options available are 3 days, 5 days and 10 days for 2 layer PCB. You can also see more detailed specifications here. We also tell you what are the most common mistakes to avoid when ordering our Standard PCB prototypes.

All orders have to be placed online with payment strictly by credit card payment

After you place your online order, we expect you to email us your design files in Gerber 274X format.

What if my board specifications do not meet your online specials, or what if I want faster turn-times than you offer online? How do I get a quote?

We find that a vast majority of our customers can easily use our Standard PCB or Bare PCB promotions online. If your board does not fit the specifications of those fantastic online specials or if you want fast 24 hour turn time etc, then we will happily get you a custom quote here.

Your custom quote will be sent as soon as possible (generally within 2 hours).

I am new to PCB prototyping, how can PCB1STOP help?

We encourage our users to review our “New to PCB Prototyping” section for tips and pointers on getting started in this industry. Additionally you can visit our Glossary section.

Does PCB1STOP do business with PCB buyers and designers outside USA also?

Apart from customers in USA, we serve customers in many countries including Italy, France, New Zealand, Denmark, Malaysia, India etc. We send boards to them by FedEx International.

How can PCB1STOP offer such low prices?

For our lowest priced PCBs we go the extra mile to get cost-benefits for you. Like most of our competitors in the low priced PCB market, we panelize your data with data from other orders to reduce panel costs. We have proprietary software that enables us to do this panelization quickly and easily. Our Engineering department is a network of engineers working out of their home-offices over fast and secure VPN connections.

This allows us to reduce our fixed costs. We have close relationships with well-regarded vendors to use their excess capacity to make our PCBs at low prices. All this effort results in low price per panel and we pass on all the savings to you!

What is your guarantee? What if I am not satisfied with the boards I receive?

Our prototype PCBs are made in ISO 9001:2008 certified facilities and are manufactured to IPC-A-600F Class 2 specifications and guidelines.

GuaranteeAlthough we aggressively cut costs to benefit you, we never compromise on quality. We stand behind the boards we make and are committed to your satisfaction. If your printed circuit boards are not made to your specifications, we will remake them immediately. On your part, you can help us by making sure the data you provide is accurate, complete, and contains no discrepancy in information.

Please note: We have essentially two kinds of “products”: either simple online specials, or custom quoted jobs (generally more complex)

For online specials we make exactly what you give us. We do not open the Gerber files to do a design rule check (DRC) unless you specifically ask and pay for it. In other words, if you order an online special, you get fantastic low prices, but whatever you design is what you get.

For custom quoted jobs, we always do a full design rule check to catch mistakes (for example does your design lead to solder mask in vias etc). Custom quoted jobs are also fully electrically tested.

What are typically the specifications that my PCB design needs to conform to so that I take advantage of your great online prices?

Click here to see the typical specifications needed for 2 to 6 layer boards. When you are placing an order online we will again show you such specifications and at that time you must ensure that your boards meet those specifications. Of course, if your boards are very different from these specifications, you can ask us to get you a custom quote.

How can I make sure my job is not put on hold? What are the most common mistakes that I can avoid?

Getting your order to you on time is a shared responsibility. We will use ISO 9001:2008 facilities to manufacture to the specs you provide and to ship your boards on time. And you can do your part by avoiding some common pitfalls:

– Make sure none of the files you send us are corrupt.
– Make sure Fabrication Print is provided and it is not missing any of the following:
Fabrication

  • Material type and finished thickness of the board.
  • Finished copper weight
  • Board dimensions and outline
  • Cut outs or slots information (if cutouts & slots are allowed in the product you are buying; check the product specs)
  • Board Construction information

Also ensure that:

  • There are no discrepancies between Gerber data and Fabrication Print.
  • In our Online Specials while we generally expect rectangular boards, we will allow rounder corners (minimum 25 mil radius). Note that at least ONE corner must be a 90 degree corner.We also allow up to 8 Notches (as long as they are atleast 50 mils wide and 50 mils deep). We also allow chamfered corners (at 45 degrees). See some examples of outlines here. We reserve the right to reject very complex outlines.(For custom quoted jobs, of course, there are no restrictions on outlines.)
  • Drill file is not missing and Drill file is Excellon format
  • There are no Missing holes
  • Plated and Non-Plated holes are clearly defined. Please check our product definition page when you are placing an order. The maximum size of plated holes allowed is 246 mils and the maximum size for non-plated holes is 250 mils.
  • For multilayer boards, on the inner layers, please make sure the edge of hole to edge of another hole is minimum 16 mils, and edge of hole to trace is minimum 10 mils. See details/pictures/examples here. (This is applicable to online specials only, not for custom quoted jobs.)
  • To get our most aggressive pricing, please ensure all holes in your design are Plated holes. If you have any Non-Plated holes there will be an extra $50 charge on your order. Also make sure your non-plated holes follow the “2 Rules for Non-Plated Holes” mentioned below in this FAQ. (This is applicable to online specials only, not for custom quoted jobs.)
  • For plated holes, the Annular Ring should be AT LEAST 5 mils wide. For example: If your finished hole size is 125 mils diameter, with annular ring, the pad diameter should be AT LEAST 135 mils (which is, 125 + 5*2 ). (This is applicable to online specials only, not for custom quoted jobs.)
  • Aperture list is provided.
  • Gerber files are scaled one to one.
  • Thermal connections are not missing on plane layers.
  • All board construction notes are on the Fabrication Drawing. Your board construction notes should not be scattered around in multiple documents. We are liable for the board construction notes on the Fabrication Drawings only.

We expect files to be in positive format, except if it is an INNER layer that is a plane layer we prefer Negative format. See why we have this requirement. For our online promotions, we EXPECT ONLY ONE FILE per layer. In other word, we DO NOT accept composite layer files. However mixed layer files are accepted.

What is a Negative Plane Layer?

This is the representation of a plane layer in your CAD software, where the background represents copper and the colors in the plane layer represent non-metal areas. (Generally for all other layers, you would want the color to represent the copper traces (ie Positive Format) — it is only for INNER PLANE layers that we need this negative format). Most CAD software these days by default automatically output INNER PLANE LAYER data in negative format. But please make sure your files are in this format before you send them to us.
