Guide for Accurate PCB Fabrication Quote Requests
Sending a PCB fabrication quote request with incomplete or unclear information almost guarantees delays, price changes, or unexpected questions from the manufacturer. A clear, step-by-step approach helps you get fast, accurate quotes and makes it easier to compare manufacturers on real capability and value, not just headline price.
This guide walks through the essential steps for an accurate PCB fabrication RFQ and explains how working with a capable partner such as MorePCB helps avoid common manufacturing problems.
Step 1: Define your PCB basics clearly
Before asking for any quote, make sure the core PCB specifications are well defined. These basics are the foundation of the price, lead time, and feasibility assessment.
Include at least:
- Board size and outline: Dimensions (length, width) and final outline shape, including slots or cutouts if applicable.
- Layer count and stackup: Number of layers (single, double, multilayer) and whether you need a specific stackup or impedance control.
- Material type: Standard FR-4 or special materials such as aluminum for power/LED boards, or PTFE/Rogers and ceramic for RF and high-frequency designs.
- Final thickness and copper weight: Overall board thickness (for example 1.6 mm) and copper thickness (for example 1 oz or higher for power designs).
Providing these details upfront allows the manufacturer to check technology fit and avoid later redesigns.
Step 2: Prepare clean Gerber and drill files
Accurate PCB quotes depend heavily on the quality of your manufacturing data. Gerber or ODB++ files let the factory extract exact information on layers, features, and holes.
Make sure you:
- Export all layers: At minimum, top and bottom copper, internal layers (for multilayer), soldermask, silkscreen, and board outline.
- Include drill files and drill map: Through-holes, vias, and any special holes or slots should be clearly defined, including plating information.
- Use consistent naming: Layer names should clearly reflect their purpose (for example, “Top_Cu”, “Bottom_Silk”), making it easier for CAM engineers to process your job.
- Note special features: Impedance-controlled traces, rigid-flex areas, or heavy-copper regions should be identified in fabrication notes.
Manufacturers like MorePCB often provide free Gerber reviews to catch obvious data problems before fabrication, which helps avoid delays and scrap.
Step 3: Specify manufacturing tolerances and finishes
Surface finish and tolerances have a direct impact on cost and performance. Being explicit in your quote request ensures you receive boards that match your real needs, not just generic defaults.
Key items to include:
- Minimum track/space: The smallest copper width and spacing used in your design, for example around 2.5 mil.
- Smallest hole size: The minimum mechanical drilled hole (for example 0.15 mm) and any microvias if applicable.
- Surface finish: Indicate whether you need HASL, lead-free HASL, ENIG, OSP, or another finish based on solderability and reliability requirements.
- Soldermask and silkscreen: Color preferences (for example green mask with white silkscreen) and any special instructions such as selective openings.
Top manufacturers can work within tight tolerances, but they still need them defined in the RFQ to quote correctly.
Step 4: Include quantity, delivery, and test requirements
Two quotes for the same design can differ significantly based on quantity, schedule, and testing scope. Being precise about these elements keeps expectations aligned.
In your quote request, describe:
- Quantities and build strategy: Prototypes only, prototypes plus small batch, or volume production, and whether you expect repeat orders.
- Lead time expectations: Standard or expedited delivery, and whether you can accept partial shipments.
- Testing needs: Electrical testing (E-test), flying probe vs fixture test, or additional checks such as impedance test or microsection reports.
MorePCB supports quick-turn prototypes as well as higher-volume runs, making it easier to keep using the same partner as your requirements grow.
Step 5: Decide if you need PCB assembly in the same quote
Many projects benefit from combining PCB fabrication and assembly in one RFQ. This reduces vendor management and often results in better overall cost and lead time.
If you want a combined PCB + PCBA quote, include:
- BOM file: A clear, well-formatted Bill of Materials with manufacturer part numbers, quantities, and approved alternates.
- Assembly drawing and notes: Orientation marks, polarity indicators, special assembly instructions, and any no-stuff locations.
- Assembly type: SMT, through-hole, or mixed-technology, and whether you want turnkey, partial-turnkey, or consigned components.
MorePCB’s PCBA capabilities cover SMT, through-hole, and mixed-technology assembly, with support for small 01005 packages, fine-pitch BGAs around 0.2 mm, AOI, and X-ray inspection. This allows you to request a single integrated quote that includes fabrication, component sourcing, assembly, and testing.
Step 6: Choose a manufacturer with proven capabilities and global reach
Even a perfect RFQ will not help if the manufacturer lacks the capabilities your design requires. Evaluating suppliers on technology depth and service—not just price—helps avoid quality problems later.
From its capabilities, MorePCB provides:
- Flexible PCB fabrication: Support for 1–50 layers, copper thickness from around 0.5 oz to 12 oz, board thickness from 0.1 mm to 10 mm, and fine features such as 2.5 mil track/space with small drill sizes down to about 0.15 mm.
- Broad material and finish support: FR-4, aluminum, PTFE/Rogers, and ceramic boards with surface finishes including HASL, ENIG, and OSP to match different performance and budget levels.
- Full PCB assembly services: Surface-mount, through-hole, and mixed assembly, turnkey or partial-turnkey sourcing, and quality inspection through visual checks, AOI, and X-ray.
MorePCB also offers no minimum order quantity, free Gerber and BOM checks, and serves customers globally, which helps makers, engineers, and companies anywhere move from idea to production using the same partner. When your quote request is detailed and the manufacturer is capable, you significantly reduce risk and speed up every stage from RFQ to delivered boards.
FAQ
Q: Why is an accurate PCB fabrication quote request important?
A: An accurate PCB fabrication quote request reduces misunderstandings, speeds up response times, and helps manufacturers calculate realistic pricing and lead times. When your specifications and files are clear, you avoid repeated questions, hidden costs, and build delays.
Q: What files do I need for a PCB fabrication quote?
A: You typically need Gerber or ODB++ files, drill files, a clear board outline, and notes on materials, layer count, thickness, copper weight, and surface finish. Providing these together makes it easier for the manufacturer to check feasibility and respond with an accurate quote.
Q: What PCB capabilities does MorePCB support?
A: MorePCB supports 1–50 layer PCB fabrication with copper thickness ranges from about 0.5 oz to 12 oz and board thickness from 0.1 mm to 10 mm, along with fine track/space and small mechanical drill sizes around 0.15 mm.
