Our goal at Largo Circuit Design is to produce the highest quality designs in the most expedient way possible. The most effective way to achieve our customer’s goals is to be flexible and attentive.
Here we outline our work process on a typical design job. It describes the input requirements, milestones, options and deliverables.
While this is not intended to serve as a a contract or an agreement, our intention is to familiarize you with the design process and to enhance the communication between our service bureau and our clients.

First, a quote will be provided within 24 hours. A price estimate will be provided if no minimum input is provided.
Standard Input | This is the information we typically prefer to have to prepare an accurate quotation.
Minimum Input | This is the minimum information we need to prepare an accurate quotation.
It is best to start a job when all the items listed on the “Standard input” are available.
This way the “clock starts ticking” and the work can be continuous and flow uninterrupted.
Standard Input | Needed data
Minimum Input | We can start working once we have these items
For boards that have critical design parameters, like impedance control, fine lines, tight spacing and the like, it is recommended that a board manufacturer be selected early on and be put in touch with us. This way the critical board parameters will be reviewed and approved by the manufacturer and guaranty smooth transition to fabrication.
After all necessary data has been received and processed, the board parts placement will be completed and the following items sent to the customer for approval:
If the customer has comments regarding the parts placement, they will be implemented and a new set of files will be sent for approval. This process will repeat until the customer is satisfied and approves the placement. At this point routing can begin.
During the routing phase all the board interconnections will be made, as well as parts renaming and silk screen (legend) design. The following items will be sent to the customer for approval:
The customer needs to approve the routing and silkscreen as depicted in the plots.
If the customer has comments regarding the routing, they will be implemented and a new set of files will be sent for approval.
This process will repeat until the customer approves the routing. At that point the board is ready to be finished and the design package
can be completed.
After routing approval, all remaining tasks are completed. Using an extensive checklist, all aspects of the design will be revisited and checked and the design package items will be created.
The Design Package / Deliverables include:
Other items are available and will be delivered at that point, if ordered:
If prototype manufacturing and/or assembly is ordered directly from Largo, it will start immediately after the design package is completed, unless otherwise instructed by the customer.
Changes during the original design cycle:
It is well known and understood at Largo that changes and modifications are an almost unavoidable part of the design process.
A reasonable amount of time (up to 6 hours) is allocated for E.C.O.s in the original price.
The customer has to be aware that excessive changes might disrupt the work scheduling and result in delays longer than the actual time they take to implement.
To minimize the adverse impact on cost and schedule, the customer is encouraged to notify Largo as early as possible about impending changes.
New revision changes:
After a design has been completed and delivered, the project is considered closed. Any changes from that point on are consider a new job (Revision role).
Largo Circuit Design is a leading
Printed Circuit Board (PCB)
design company based in California.
