For clients that have complete & final design packages with well
defined requirements, Via Technology offers fixed price layout services.
Required Design inputs for Flat Rate PCB Designs
Complete and final schematics
Bill of Materials (BOM) - complete and final with part manufacturers
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 constraints - identify any constraints on board size,
shape, keep out areas, vertical clearance constraints, keep out
requirements, mounting hole provisions, etc
Special considerations or design guidance - such 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 first 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 that if you change the BOM, mechanical guidance, or
special design guidance after placement begins, it may cause us extra
work and result 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
for your design (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 for 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.
