Terms & Conditions

GENERAL TERMS & CONDITIONS

Leverage agile frameworks to provide a robust synopsis for high level overviews. Iterative approaches to corporate strategy foster collaborative thinking to further the overall value proposition. Organically grow the holistic world view of disruptive innovation.

• 
  All orders are FOB Oak Creek, Wisconsin, USA unless otherwise specified within the quote. For deliveries outside of the USA, all duties and customs are the responsibility of the customer, unless otherwise agreed upon in writing.
  
• 
  Prices are quoted in US dollars; taxes and shipping charges are extra as applicable.
  
• 
  Custom quotes provided to you are only valid for 30 days unless otherwise agreed upon in writing by our representatives.
  
• 
  Payment is due within 30 days of receipt, unless we expressly agree to otherwise at the top of the Quote.
  
• 
  Prices shown on this document are based on information provided by the customer’s Gerber files and associated instructional documents at date of quotation/order. To facilitate quick-turns, customers sometimes request us to release orders with a pending PO. Any changes requested to PCB manufacturing processes after placing order, or any new details that emerge in a pending PO, may result in additional charges.
  
• 
  The turntime shown is calculated using business days. Weekends and business holidays are excluded in any turn time calculations. Additional turn days may be added to orders that are placed “On Hold,” waiting for customer response for resolution of missing information or discrepancies.
  
• 
  Credit application.
  

PCB FABRICATION TERMS & CONDITIONS

Sale subject to limited warranty (details in Limited Warranty section below). Warranty extends only to bare PCBs and does not apply after components are added by you or others. Our liability shall not exceed the price paid by you for the ordered PCBs. No change or addition to these terms, or any additional or different terms on your purchase order, shall be binding on us unless executed in writing by one of our officers.

If IPC Netlist is not provided in 356 format, Sierra Electrotek will create a net-list from the incoming customer Gerber files to generate an electrical test program. In such cases, Sierra Electrotek cannot guarantee, nor can it be liable for the electrical performance of the boards, since the test program itself is derived from the files submitted. If you send us your design files in multiple formats (say, Gerbers and ODB++) it is your responsibility to ensure that the design in both formats is the same. We reserve the right to use any of the formats sent to us and will not cross-check between formats for consistency.

Manufacturing optimizations

As with most other PCB manufacturers, we may make simple optimizations to your design to ensure boards are manufactured correctly. Such changes do not affect the electrical functionality of your design.

These may include:

• 
  Teardrops may be added to pad/trace interfaces to ensure better connectivity.
  
• 
  Slivers less than .005″ may be filled in to prevent resist slivers on the panels.
  
• 
  Soldermask dams that are less than .004″ wide between SMD pads which have a .003″ minimum clearance may be gang relieved.
  
• 
  Silkscreen may be clipped to ensure it does not get on top of pads/copper features.
  
• 
  Non-functional pads may be removed from inner layers.

DFM & DFA

Once your order is received, it may go through a quick design for manufacturing (DFM) and design for assembly (DFA) analysis, to prevent any holds during manufacturing and assembly. If we find any issues, these must be resolved promptly. We may contact you by phone/email as needed.

We cannot start manufacturing if such issues are unresolved. An unreasonable delay in resolving issues may push out your delivery date accordingly.

(Note: We only do a DFA on orders that include Sierra Circuits assembly services. An example of a DFA issue: The landing pads on your board don’t match the footprint for component C12.)

YOUR RESPONSIBILITY TO HELP ENSURE DELIVERY DATES ARE NOT CHANGED

When you place your order our engineering team will start working on it (mostly DFM/DFA checks), and identify any discrepancies or missing information and will contact you by email/phone, likely using your 24 hours contact number.
In order to ensure on time completion of your order, you must respond to such communication promptly, so that the delivery date is not affected.
If your order is for a very fast turn (1 or 2 day turntime) and your responses are delayed by more than 1 hour, it might lead to a change in the delivery date.
If your order is for 3 days or more and your responses are delayed by more than 3 hours, it might lead to a change in the delivery date.

WARRANTY

This warranty is nullified on products which have been subject to misuse (including static discharge), neglect, accident or which have been altered by you and are not capable of being tested. Sierra Electrotek is not responsible for any damage or lack of functionality caused by defective design, components or PCBs provided by you or as a result of deficiencies in the electronic materials provided by you.
