We are experts in PCB design with a solid reputation in high speed digital, analog, mixed-signal and RF systems. We design single, double, and high layer count (Up to 32 layers), Rigid, and Flex-Rigid printed circuit boards. Whether your project entails high speed constraint-driven requirements, routing, or basic I/O, our engineers and technical staff has the expertise to deliver comprehensive designs that are top quality, well-managed, and on-time.
Our mature engineering methodology ensures efficient, cost effective designs, done right the first time. We offer 2 stage design reviews, either offline or interactive online. Designs can be provided using industry standard PCB design software:
- Cadence (ORCAD & ALLEGRO)
- CADSoft (EAGLE)
- Mentor Graphics (PADS)
- Altium (Altium Designer)
We have extensive experience in creating RoHS compliant designs for new layouts and conversions of existing assemblies. Also, ask about our reverse engineering capabilities, as we can convert an existing board assembly without documentation into a complete and functional database.

CAD Tools & Data Importing
PCB Unlimited uses Cadence's Allegro, OrCAD Layout and Mentor Graphics PADS for schematic capture & printed circuit board design.
Net list data from other CAD systems can also be used. We can import AutoCAD drawings to capture mechanical constraints for board
layout as well as export mechanical data.
PCB Design Service Terms & Conditions
What are the terms and conditions?
Our Online quotes are based on number of layers, PCB shape, size and
dimensions, and design complexity.
Offline quotes are provided after studying the necessary input documents.
Following documents are required for providing an offline quote:
- Bill of Material
- Mechanical Specifications
Feedback Reviews & Changes
Once the project is started, after receiving the required input documents,
we will provide you the component placement drawings in PDF format.
It is customer’s responsibility to ensure that the component placements and
its foot prints are satisfactory. Based on the feedback we will update the
component layout and complete the routing. The routing documents are again
provided as pdf documents or Gerber files. Customer at that stage can
approve the design based on the documents sent or request an online review.
Online reviews can be done over any of the free desktop sharing tools
available such as SKYPE.
Once the customer accepts the project, a tentative project schedule will be
given with anticipated dates for component placement, and routing approval
and total project timelines.
At any point of design cycle, if the design requires advanced techniques
such as impedance matching, signal integrity checks, thermal simulations,
revised project cost and timelines will be offered to the customer for their
- Your are billed in two 50% increments
Credit Card (MC of VISA) will be charged the first 50% at the time the
order is placed.
The second 50% is due at the completion of the Interactive Part
- Your PCB layout is non-refundable.
Unused extra design hours (purchased after submitting your order)
We have experienced layout designers and we are committed to customer
satisfaction. However, the final responsibility for design functionality
and manufacturability are yours. We give no warranties regarding the
design of your PCB.
In no event shall our liability exceed the amount of the order placed.
We give no other warranty, either expressed or implied, and
specifically disclaims all other warranties, including warranties for
merchantability and fitness.
