Web PCBs - our new online offering! |
|
|
Our new promotion, Web PCBs, is the fastest and most convenient way for you to get PCBs online. On your Web PCB orders, our CAM Engineers personally verify your design for manufacturability (DFM), so you get Sierra's famous quality and quick turn times--all at low prices. And we provide NRE/Tooling for free. Keep that in mind as you compare our prices to anyone.
We recommend our Web PCBs if you need standard 2-12 layer printed circuit boards, no minimum quantity, standard FR-4, hi-temp FR4, and other materials available, many surface finishes available (HAL (Solder finish), Lead-free HAL,
Hard Gold, Immersion White Tin, Immersion Silver, etc.), different copper weights, 1 day thru 4 weeks turns and with controlled dielectric/impedance and Electrical Testing options. We provide these from prototype quantities to medium production volumes… and all of this instantly quotable and orderable online!
For your convenience, we show two sets of Pricing Matrices when you quote Web PCBs.
- MATRIX 1: Custom Spec: Here we show prices for EXACTLY your quoted specs-- whatever you have chosen --special material, special finish, soldermask and silkscreen colors and any other special processes --Eg. Controlled impedance, counterbores, etc.
- MATRIX 2: Pre-defined Spec: Here we show prices ASSUMING that board is a simple, standard-technology PCB: E.g., material is FR4, 0.062" thick, Solder finish, Green Soldermask, White silkscreen, standard construction, no special processes etc. We find a vast majority of PCBs fit these specs. By agreeing to let us build to standard pre-defined specs, you can get lower prices for your boards.

What are the Terms & Conditions for the Web PCBs?
In the Web PCBs offering, there are two promotional matrices shown when you quote:
Pre-DEFINED Specs matrix and Custom Specs matrix.
In Pre-DEFINED specs the Terms are:
- Pre-defined spec pricing assumes HAL plating, FR4, 0.062", all holes plated thru (PTH), green mask, white silkscreen, and non-plated slots (if any). We will use our standard copper plating (1 oz Outers and 0.5 oz Inners). Also, in your design the minimum trace / space has to be 6 mils (0.006") or more; and Minimum hole size 8 mils (0.008") or more. These specs will override any contrary specs in your files or quote.
- DOES NOT include UL markings, 94V-0 and date codes. Finished hole tolerance +/- .005".
- All files receive full CAM review and inspection to IPC-A-600G, Class 2 standards.
- If your design includes countersink/counterbore or if you have controlled dielectric/stackup or impedance requirements, refer to Custom Spec matrix.
- We do not charge for NRE/Tooling. It is free!
- Electrical Testing is optional for 1 to 6 layer boards. For boards with more than 6 layers, Electrical Testing is mandatory.
- Unit prices shown do not include any Shipping charges or any applicable taxes.
In Custom Specs the Terms are:
- The Custom Spec Matrix reflects pricing for the EXACT SPECS you QUOTED.
- All files receive full CAM review and inspection to IPC-A-600G, Class 2 standards.
- INCLUDES UL markings and date codes. 94V-0 is added if requested at time of order entry or if noted in files. Finished hole tolerance +/- .003 (if requested).
- We do not charge for NRE/Tooling. It is free!
- Electrical Testing is optional for 1 to 6 layer boards. For boards with more than 6 layers, Electrical Testing is mandatory.
- Unit prices shown do not include any Shipping charges or any applicable taxes.
- Gerber files using English units in 274X format or ODB++ format.(Note: 274D format is not accepted)
- Fabrication Print in Gerber format, showing the board outline with drill pattern and sizes.
- Exellon drill file in ASCII format with the following parameters:
- Units = Inch
- Tool Units = Inch
- Coordinate = Absolute
- Zeros omitted = Trailing
- Number format = 2.4
- ASCII text file called Readme.txt with the following critical information:
- All relevant details about the board, including thickness
- Listing of all file names and what they are. (eg top copper, top soldermask etc)
- Layer stackup sequence
- How to represent Board Outline
- We STRONGLY PREFER that board outline should be in the Gerbers-- it could be on any of the gerber layers or on its own separate layer.
- If that is not possible, our second preference would be to have the outline in the Fabrication drawing with dimensions clearly shown.
- Any other way of representing the outline would not be acceptable and your order may go on-hold.
What are the most common reasons why my web PCBs order may go on hold?
Your order may go On Hold if: - Any file is corrupt or missing from Gerber Package.
- No board outline provided, or if not provided as a gerber file.
- Discrepancies exist between Gerber and fabrication print
- Layer stack-up not defined.
- Fabrication Print is not supplied, or it is missing the following:
- Material type and finished thickness of the board
- Finished copper weight
- Board dimensions and outline
- Cut outs or slots information
- Board Construction is not defined
- Surface finish not defined
- No Drill file is present.
- Drill file is not in ASCII format
- Missing holes
- Plated and Non-Plated holes are not clearly defined
- Non-plated holes are on copper areas. (Including copper pads)
- There is no Aperture list
- Gerber data not in 274x format.
- Gerber files are not 1:1 (true size).
- Thermal connections are missing on plane layers
- Plane Layers should be supplied in negative format for the following reasons:
- Negative layers, in many cases, are not as large of a file size as positive layer files
- Negative layers are much quicker to work with when we run our Engineering Analysis
- Positive layers contribute to longer test times in final test.
- Polygons in plane layers and signal layers are not desired for the following reasons:
- Our high-end CAD software, Valor Genesis, will attempt to fill the polygons automatically but can miss some areas on the layers. This would result in missing data and possibly a non-functional board.
You will be sent an e-mail if your job goes on hold.
I understand my order may go On Hold (temporarily) if Sierra Proto Express engineers find my design is missing some information or has some discrepancy. If so, how do I get my order Off Hold?
Please provide 24 hour contact information and be available to answer any technical questions promptly.
How does the on-hold time affect the due date of my order?
The schedule is extended by the time your job is left on hold. The quicker we can get an answer, the quicker you get your job. We make a best effort to make up for lost time, but cannot guarantee it.
What is the cancellation policy for Web PCB orders?
Cancellation charges apply, depending on how far along the order has progressed. We will make our best effort to minimize cost to the customers.
How do I calculate turn time? What is the cut off time to place an order?
For all turn times (except Same Day turn): Files should be received by 5:00 PM (then this day is counted as Day 0). And the next day is counted as Day 1.
For example: If you place a 3 day turn order by 5:00 PM on Monday, then Tuesday is counted as Day 1 and the order will ship on Day 3 which is Thursday evening.
Note: Weekends and Business Holidays are not counted. When will my boards ship if I order today?
Can we do a Will-Call pickup for WEB PCBs? What are the guidelines for Will-Call?
Yes, we do allow will-calls for Web PCBs-- with the following guidelines.
- A service charge of $15 applies to every will-call order.
- On the day that your boards are due, we will give you a confirmation call by 4 PM.
- Boards can be picked up from our lobby at
1108 West Evelyn Avenue,
Sunnyvale, CA 94086.
- Your order can be picked up only between 5 to 6 pm PST.
- Please have a printed sales order confirmation ready and a valid ID.
- Once you are in the lobby, someone will help you- or you may call your Web Product Specialist.
- In the rare case when a will-call order is not ready on due date, the will-call service charges will be cancelled.
How can I establish credit?
(Note that Internet orders are through credit card (Amex/Visa/MC,Discover) only). For orders through your Account Managers, standard terms are net 30. Anything different must have written approval. Fax your credit information to 408-735-1408 with Attn: Credit Department on the cover sheet. Please fax the following: Your name, company, address, bank references and at least 3 trade references.
How are taxes calculated? What if my boards are for re-sale?
No Sales Tax is charged for orders shipped to a location outside of California. Following applies only to orders shipping to a California address: To exempt a Web PCB order from California Sales Tax, you must mark order as "Non Taxable" and mention your Resale number. You should also upload your Resale Certificate online or email it to webpcb@protoexpress.com.
