Flat Rate PCB Design

For clients who have complete and final design packages with well-defined requirements, Via Technology offers fixed-price layout services.

Required design inputs for flat rate PCB design:

  • Complete and final schematics

  • Bill of Materials (BOM)complete and final with part manufacturer's name and full manufacturer part number. For passive components such as resistors and capacitors, you may identify a standard package type in lieu of a complete part number if desired (for example resistor - 220 ohms - 0805 package)

  • Mechanical constraintsidentify any constraints on board size, shape, keep-out areas, vertical clearance constraints, keep- out requirements, mounting hole provisions, etc.

  • Special considerations or design guidancesuch as critical component placements, special spacing requirements, high current or high voltage signals, noise sensitive signals, matched impedance requirements, matched trace lengths, split power/ground planes, special pad configurations, test point requirements, use of client provided libraries or footprints, etc.

Our Layout Process

Via Technology's PC board layout process is geared toward providing our clients with opportunities for review and comment at key points.


Component Placement and Mechanicals
We start with your inputs and generate the board's mechanical layout and parts placement. Once we have a completed parts placement, we will provide it to you for review and comment. In some cases, we may first provide you with a partial placement showing critical parts placements for your feedback before we populate passive parts like decoupling capacitors.

As part of this review we expect requests for minor adjustments, and this is also the appropriate place to have your manufacturer provide DFM feedback as well. We will update the layout to address these items and ask that you approve it before we move onto routing.

Please note: If you change the BOM, mechanical guidance or special design guidance after placement begins, that may cause us extra work, resulting in a price impact for your design. If you have a .DXF or .DWG file to start with (containing mechanicals and/or key part locations, like connectors) we can save you time and money. so be sure to let us know this when you request your quote.


Board Routing
Once you have approved the component placement for your board, we will perform routing operations in accordance with any special routing guidelines that you have identified (such as controlled impedance, matched line lengths, noise sensitive traces, split planes, high current or high voltage traces, etc.).

Client collaboration is critical in achieving a successful first pass layout. You know your design in detail and we count on you to identify these types of requirements up front to avoid rework and added costs later.

Once routing is complete we will provide you with check files for your review and final comments or approval. Comments will be addressed as required and the final deliverable file set will be delivered for use in board procurement.

As with the previous step in this process, changes to parts, placement, mechanical features or design guidelines during routing will impact the final price of your layout, so we urge you to take the time up front to clearly identify your requirements and any special layout practices or preferences that you would like us to follow when routing your board.
