Step-by-Step Turnkey Assembly Process
Our turnkey PCB assembly process follows a systematic approach that ensures quality at every stage while maintaining efficiency and precision. Each step incorporates verification procedures and quality checkpoints to guarantee optimal results from design through delivery. Here’s an overview of our streamlined approach.
1
Design and DFM Review
Our engineering team reviews Gerber, BOM, CPL, and placement files to identify manufacturability issues early, helping ensure turnkey assembly processes begin with accurate inputs and fewer production delays.
2
Component Sourcing
We source components from authorized distributors or customer-provided kits. This ensures compatibility, authenticity, and strong supply chain control for consistent fabrication and assembly performance.
3
PCB Fabrication
Your bare boards are manufactured to spec: correct layer stack?up, copper weights, finish, through?via or blind/buried design, and finishing processes. This step creates the foundation for reliable assembly.
4
Stencil and Solder Paste Printing
For SMT assembly, solder paste is applied through a stencil onto pads. A solder?paste inspection (SPI) verifies the correct volume and placement of the paste, especially important for fine?pitch or high?density components.
5
Component Placement
Using pick-and-place systems with vision alignment, components are placed on the board accurately. The process supports a wide range of packages, including SMT, through?hole, BGAs, and CSPs, positioned accurately before soldering.
6
Reflow and Selective Soldering
After placement, boards pass through a reflow oven (for SMT) or selective/wave soldering (for THT). Controlled thermal profiles ensure strong, reliable joints and compliance with lead?free (RoHS) or tin?lead specifications as required.
7
Inspection and Testing
AOI, X-ray, ICT, flying probe, and functional tests confirm solder quality and electrical performance, ensuring turnkey printed circuit board assembly builds meet operational requirements before shipment.
8
Conformal Coating or Potting
For assemblies subject to harsh environments or reliability demands (e.g., aerospace, medical), conformal coating or potting is applied to protect against moisture, vibration, and dust.
9
Final Inspection, Packaging, and Shipment
Completed assemblies undergo visual checks, labeling, documentation, and secure packaging to maintain traceability and safe delivery.

FAQs
Can I request design adjustments before assembly begins?
Yes, you may ask for design improvements or updates before production starts. Engineering teams review data to highlight areas that may affect performance or manufacturability. This ensures your final product is built with the most reliable structure.
Can I receive a sample or pilot build before full production?
Yes, sample runs are offered to help validate design accuracy and functionality. These builds give you a clear understanding of assembly quality before scaling. It also allows adjustments to be made if required.
How are customer files kept secure during a turnkey project?
All submitted documents are stored in controlled systems with restricted access. This ensures design data remains confidential throughout the project lifecycle.
Can turnkey assembly support multi-board or modular product builds?
Yes, turnkey assembly can support multi-board or modular product builds. . These may include stacked configurations, cable harness connections, or module-based designs. All units are checked for compatibility before final integration.
Does turnkey assembly support mixed part packages on the same board?
Yes, turnkey PCB assembly services can handle mixed part packages on the same board, including small passives, large ICs, connectors, and specialized components. Different package types are managed through equipment capable of precise placement. This offers flexibility for complex layouts.
