The journey from a PCB design file to a fully assembled, tested board involves multiple precision processes. Understanding this workflow helps engineers design for manufacturability and ensures smoother production runs.
The Complete PCB Assembly Workflow
1. Design Review
DFM analysis, Gerber verification, BOM validation, and component availability check.
2. Stencil & Setup
Laser-cut stencil fabrication and SMT line programming for your specific board.
3. Solder Paste
Precision solder paste application using automated stencil printing.
4. Component Placement
High-speed pick-and-place machines position components with micron accuracy.
Reflow Soldering Process
After component placement, boards travel through a reflow oven with carefully controlled temperature zones:
- Preheat Zone: Gradual temperature rise to activate flux and prevent thermal shock
- Soak Zone: Temperature stabilisation for uniform heating across the board
- Reflow Zone: Peak temperature melts solder paste to form joints
- Cooling Zone: Controlled cooling to create strong, reliable solder joints
Lead-Free Compliance
All our assembly processes are RoHS compliant, using lead-free solder pastes and meeting international environmental standards.
Quality Assurance
Every assembled board undergoes rigorous inspection:
- AOI (Automated Optical Inspection): High-resolution cameras detect placement errors and solder defects
- X-Ray Inspection: For BGA and hidden joint verification
- Functional Testing: Custom test fixtures verify board operation
- Visual Inspection: Final human verification before shipping
