Engineering Level

Sunstone offers two options to allow you to specify how your designs are to be built. These Engineering Level choices "No Engineering - Run As Sent" and Engineering Review - (NRE)" give you the flexibility to communicate how Sunstone should handle your particular design. 

No Engineering - Run As Sent:  This Engineering level is perfect for the order that does not require additional up front engineering.  This might be a design that is a proof of concept, fit test board, prototype, a well reviewed design or simply a design that has had a DFMplus pre order review conducted.  The benefits of this service are:

  • Most economical pricing available
  • Orders will not be put on hold by our tooling department (*see below for exceptions) 
  • Parts built to IPC-A-600 class 2 (when permitted by design)
  • Many PCB options available (mask color, copper weights, surface finishes etc.)

Orders placed with the Run As Sent option will be processed through tooling without making any edits to the files.  Orders will not have any upfront QC of the files and any errors contained in files will not be caught prior to manufacturing.  Print / electronic notes and PO notes will not be considered during the manufacturing and the order form will be the sole source of manufacturing information.  Please ensure that all of the files specified on your order are contained in your uploaded files (proper number of copper layers, silk layers and soldermask layers). 

*A Run As Sent order will be put on hold if

  • The number of layers contained in the files does not match the order form.  2 copper layers contained in the files and a 4 layer board ordered.
  • The board size contained in the submitted files varies drastically from the order form. 

    1.  Board size ordered is 2.312" x 3.750" and actual file dimensions are 5.00" x 12.00".  (we would place order on hold and question for new files)

    2.  Board size ordered is 2.312" x 3.750" and actual file dimensions are 2.370" x 3.810"  (we would NOT hold and question for new files)

Engineering Review (NRE): This engineering level provides additional checks of your files and print notes to ensure that the design is manufacturable, compare the order form to the prints, allow for tooling edits for manufacturability and functionality.  Perfect for orders that require higher levels of rigor (production quantities, penalization, higher layer counts etc.), peace of mind for the designer, or more complex designs.  An NRE charge is applied to all new orders (does not apply to reorders).  Benefits of selecting the Engineering Review (NRE) :

  • ​Design review of your order to ensure manufacturability and provide tooling edits as required.
  • Communication with Sunstone tooler's to rectify any concerns that may arise in review of files. 
  • Designs built with all of the print / electronic notes contained in the files. 
  • Many PCB and inspection options available.
