Inputs Required for PCB Design
- Schematic (soft copy/hand drawn)
- Bill Of Material along with manufacturing part number
- Mechanical drawing/dimensions
- Critical component placement
- Keep-out area
- Product specifications
- Environment where the PCB will be installed
Lead time
- We confirm the lead time once we have received and reviewed all the required data.
- Simple boards are typically completed within 2-3 working days.
- Moderately complicated boards take around 5-7 working days.
- High-density or complex boards usually require 10-15 working days.

FAQ's
If I do not have a soft copy of the schematic?
We prefer a soft copy of the schematic for easy extraction of the netlist, which reduces lead time. However, we can also accept hand-drawn schematics, though this may increase the lead time.
Is it necessary to provide a BOM along with the schematic?
Yes, a Bill of Materials (BOM) is necessary to determine footprints for component placement. We ensure your data is secure with us, and if needed, we are happy to sign an NDA.
What is your lead time for a quote?
We provide a quote after receiving and reviewing your inputs. If all information is provided according to your requirements, we will send the quote within 12 hours.
Do you handle mechanical or housing restrictions?
Yes, we do. To address these, we require detailed drawings or DXF files from you.
What are the alternatives if the design doesn’t fit the given size?
Our engineers will work with you at each stage of the design process. If there are issues, we will help revise your design parameters accordingly.
Do you use Auto-Routing?
We use Auto-Routing to assess the feasibility of PCB routing and to verify if the layout fits within the specified size. For the most part, we rely on manual placement and routing based on the circuit's flow. However, we manually handle the routing of DDR buses, differential pairs, and matched impedance traces.
What are your check points for design review?
We review the design at each stage. For more details, refer to our PCB design flow chart.
Do you follow DFM (Design for Manufacturability)?
Yes, our design team works closely with the FAB team, ensuring standard DFM methods are followed.
Do you consider manual/auto assembly restrictions?
Yes, we use footprints that accommodate both manual and auto assembly. Our internal assembly team ensures this process runs smoothly.
What are the charges for revisions/modifications?
We don’t charge extra for minor changes, but major modifications may incur charges. Estimates are provided after reviewing the changes.
What if we need to cancel the order due to revisions?
If you cancel the order after revisions, you will still be required to pay for the work done.
Do you reverse engineer bare PCBs?
We can reverse engineer simple PCBs along with their schematic. We can confirm this after receiving the necessary inputs from you.
Do you take on new ideas or concept projects?
Stream PCB specializes in PCB design, fabrication, assembly, and component procurement, and does not engage in new idea or concept project development.
