The Step-by-Step Instant Turnkey PCBA Quoting Process

Modern online quoting platforms streamline turnkey PCBA pricing into three simple, intuitive steps. By following these steps and providing detailed information, you ensure your quote is accurate, comprehensive, and delivered in minutes.

1. Enter Detailed PCB Specifications

The first step to a precise quote is inputting your PCB’s technical details. Online platforms guide you through a structured form to capture critical parameters, which directly impact cost, manufacturability, and lead time. Be prepared to provide the following:

• Board Dimensions & Layer Count: Specify length, width, and thickness (e.g., 100mm x 80mm x 1.6mm) and layer count (2-layer, 4-layer, or up to 10+ layers for complex designs). More layers or larger sizes increase material and fabrication costs.
• Material Type: Choose the substrate material (e.g., FR-4 for standard applications, polyimide for flex PCBs) and thickness (common options: 0.8mm, 1.6mm, 2.0mm). FR-4 is the most cost-effective for most industrial and consumer projects.
• Copper Weight: Select copper thickness (1 oz, 2 oz, or 3 oz)—a key factor for current-carrying capacity. 1 oz copper (35µm) works for low-power designs, while 2 oz (70µm) is ideal for high-current applications (e.g., power supplies).
• Trace & Spacing Requirements: Provide minimum trace width (e.g., 5mil, 8mil) and spacing (e.g., 5mil), as tighter tolerances (e.g., 3mil) require more advanced fabrication and increase costs.
• Hole Details: List total hole count, hole diameter range (e.g., 0.3mm–1.0mm), and annular ring width (minimum 7mil to prevent pad lifting).
• Solder Mask & Silkscreen: Choose solder mask color (green, blue, black, or red) and type (LPI—Liquid Photoimageable, the industry standard) and silkscreen color (white is most common for readability).
• Special Features: Note slots, cutouts, or notches (with dimensions) and controlled impedance requirements (e.g., 50Ω, 100Ω) for high-speed designs (e.g., IoT sensors, RF modules).
• Certifications: Specify required standards (e.g., ISO 9001 for quality, IPC-A-610 Class 3 for mission-critical applications like aerospace, RoHS for environmental compliance).

Pro Tip: Double-check your specs before submission. Incomplete details (e.g., missing layer count) or errors (e.g., incorrect trace width) can delay your quote or lead to unexpected costs later. Most platforms include tooltips to clarify technical terms (e.g., “annular ring”) and prevent mistakes.

You’ll also need to define project timelines: select your desired lead time (standard: 4–6 weeks; expedited: 1–2 weeks) and preferred shipping method (FedEx, UPS, or DHL for international delivery). Payment terms (e.g., credit card, bank transfer) are also specified here, with options for purchase orders for enterprise clients.

2. Upload Your BOM & Gerber Files

The BOM and Gerber files are the backbone of an accurate quote—they tell the platform exactly which components to source and how your PCB should be fabricated. Follow these guidelines to ensure smooth processing:

BOM Requirements

Your BOM must be clear, complete, and formatted for automated analysis (preferred: .xls or .xlsx). Include the following:

• Part Numbers: Use manufacturer part numbers (e.g., “RC0603JR-0710KL” for a resistor) instead of generic descriptions—this ensures the platform sources the correct component.
• Reference Designators: Match part numbers to their positions on the PCB (e.g., “R1,” “C2”) to avoid placement errors.
• Quantities: List the number of each component needed per board, plus a small buffer (5–10%) for assembly waste.
• Special Notes: Mark “Do Not Install (DNI)” or “Do Not Populate (DNP)” components and include an Approved Vendor List (AVL) if you have preferred suppliers (e.g., Digi-Key, Mouser).

Gerber File Requirements

Gerber files (or ODB++ files, the modern alternative) are digital blueprints of your PCB. Ensure you upload:

• All Layers: Include copper layers (top/bottom, inner layers), solder mask (top/bottom), silkscreen (top/bottom), and drill files ( Excellon format) to avoid missing critical details.
• Assembly Drawings: Attach a .pdf of assembly instructions, including component polarity (e.g., diode direction) and test point locations.
• Centroid File: A CSV or TXT file with component coordinates and rotation angles—this helps the platform verify placement feasibility and calculate assembly time.

Pro Tip: Use the platform’s file validation tool (most include one) to check for errors before upload. Common issues like missing drill files or mismatched part numbers in the BOM/Gerber can cause quote delays. For example, if your Gerber shows a BGA component but your BOM lists a different footprint, the platform will flag this for correction.

3. Customize Assembly Options

Every PCBA project has unique needs—online quoting platforms let you tailor assembly services to match your requirements. The table below outlines common options and their benefits:

Assembly Option	Description	Ideal For
SMT Assembly	Surface-mount component placement (e.g., 0402 resistors, BGAs) with RoHS/ISO 9001 compliance. Uses automated pick-and-place machines for precision.	Miniaturized designs (e.g., wearables, smartphones) and high-volume production.
THT Assembly	Through-hole component insertion (e.g., power connectors, large capacitors) with wave soldering for mechanical strength.	Industrial control boards, automotive electronics, or parts requiring vibration resistance.
Mixed Assembly	Combination of SMT and THT to balance miniaturization and durability.	Complex devices (e.g., medical monitors) with both small sensors and robust connectors.
IC Programming	Pre- or post-assembly programming of microcontrollers (MCUs) and memory chips (e.g., flash storage).	Devices requiring firmware (e.g., IoT gateways, smart home devices).
Conformal Coating	Protective layer (acrylic, silicone, or urethane) applied to PCBs to resist moisture, dust, and corrosion.	PCBs used in harsh environments (e.g., outdoor sensors, marine electronics).
Selective Soldering	Precision soldering for specific through-hole components (avoids heating sensitive parts).	Boards with mixed temperature-sensitive components (e.g., sensors + power ICs).
Nitrogen Reflow Soldering	Reflow soldering in a nitrogen atmosphere to reduce oxidation, creating stronger solder joints.	High-reliability applications (e.g., aerospace, medical devices).
Box Build Assembly	Full product assembly, including enclosures, cables, and mechanical parts (turns PCBs into finished devices).	End-to-end production (e.g., industrial controllers, consumer electronics).
Testing Services	AOI (Automated Optical Inspection), X-ray (for hidden joints), functional testing, and in-circuit testing (ICT) to verify performance.	All projects—critical for catching defects before delivery.
Volume Options	Flexible ordering from prototypes (5–10 units) to mass production (10,000+ units).	Startups (prototypes), small businesses (medium runs), and enterprises (high-volume).

After selecting options, the platform runs a Design for Manufacturability (DFM) check in real time. This step identifies issues like insufficient pad spacing, incompatible component footprints, or untestable designs—providing feedback to optimize your PCB before quoting. For example, if your design has a 3mil trace width but the platform’s fabrication capabilities start at 5mil, it will suggest adjusting the trace to avoid increased costs or delays.
