Files Required for Quote
Files Required for
SMT PCB Assembly Quote
To provide an accurate SMT PCB assembly quote, we need a complete set of manufacturing and assembly files. Sending the right documents at the beginning helps reduce back-and-forth communication and speeds up engineering review, sourcing and pricing.
Gerber Files
Provide complete Gerber files in RS-274X format, including copper layers, solder mask, silkscreen and drill data. These files are required for PCB fabrication and manufacturing review.
Bill of Materials (BOM)
Your BOM should include part numbers, component descriptions, quantities, package types and approved alternatives if available. A complete BOM helps speed up sourcing and quotation accuracy.
CPL / Pick and Place File
Please provide a centroid or XY placement file with component positions, rotation and board side information. This file is essential for automated SMT placement and assembly preparation.
Assembly Drawing
Assembly drawings help identify component orientation, polarity marks, reference designators and any special placement notes. This reduces misinterpretation during production.
Testing Requirements
If your project requires ICT, FCT, programming or custom test procedures, please include your testing requirements during quotation. This helps us evaluate process flow, lead time and fixture needs more accurately.
Special Process Notes
Please share any special instructions related to soldering, conformal coating, programming, cleaning, packaging or delivery requirements. Early communication helps avoid delays and engineering revisions.
If you are not sure whether your files are complete, send what you have and our engineering team will review the package before quoting.
Our
SMT PCB Assembly Process
Our SMT PCB assembly process is designed to move projects from engineering review to final delivery with speed, control and consistent quality. By combining file verification, sourcing, automated assembly and inspection, we help reduce delays and improve production readiness.
File Review & DFM Check
We review your Gerber files, BOM, CPL and assembly notes to confirm manufacturability before production starts. Early DFM and DFA checks help identify risks, reduce revisions and improve quoting accuracy.
Component Sourcing
Components are sourced according to your BOM, approved part list and project requirements. If certain parts are unavailable, our team can communicate alternative options for faster procurement and smoother scheduling.
PCB Fabrication
While component sourcing is in progress, the bare PCB is manufactured according to your approved design specifications. This integrated workflow helps shorten the total lead time for turnkey SMT assembly projects.
Solder Paste Printing
A stencil is used to apply solder paste to the required pads with controlled consistency before placement. This step is important for accurate solder volume and stable downstream assembly quality.
Pick and Place Assembly
Automated SMT equipment places components onto the PCB according to the centroid and placement data. This process supports high-speed, repeatable assembly for fine-pitch and complex package types.Step 6
Reflow Soldering
The assembled board passes through a controlled reflow process to form stable solder joints between components and pads. Proper thermal profiling helps ensure reliable attachment and electrical performance.
Inspection, Testing & Delivery
Finished assemblies go through inspection and testing based on project requirements, including AOI, SPI, X-ray, ICT or functional testing when needed. After final verification, boards are prepared for shipment and delivery.
From prototype validation to repeat production, our process is structured to keep your SMT PCB assembly project efficient, traceable and quality-focused.
Quality Assurance & Inspection for SMT PCB Assembly
Reliable SMT PCB assembly depends on more than placement accuracy. At Vonkka PCB, quality control is built into the process through engineering review, in-process inspection and final testing based on project requirements.
DFM & DFA Review
Solder Paste & Placement Control
AOI & SPI Inspection
X-Ray Inspection
