Our PCB Assembly Process
From engineering review to final delivery, Kingda provides coordinated PCB assembly services tailored to your design and production requirements.
We Work Strictly And Rigorously!
From engineering review and component sourcing to SMT assembly and THT assembly, quality inspection and final delivery, each stage is coordinated according to the project’s technical requirements.
As a one-stop electronics manufacturing service provider, Kingda supports prototype PCB assembly, small-batch production and repeat manufacturing. Whether you require turnkey PCB assembly or assembly using customer-supplied components, the process is tailored to your design, production volume and quality requirements.
A Structured Process for Reliable PCB Assembly
A successful PCB assembly project depends on more than accurate component placement. Design compatibility, material availability, soldering parameters, inspection methods and production planning all influence the final result.
Kingda follows a coordinated manufacturing workflow to identify potential issues before production, control critical assembly operations and verify product quality before shipment.
Our PCB assembly process includes:
- Project review and engineering analysis
- PCB manufacturing and component sourcing
- Material verification and preparation
- SMT assembly and reflow soldering
- THT assembly and mixed-technology processing, when required
- Quality inspection and electrical or functional testing
- Final quality checks, packaging and delivery
The exact process sequence depends on the PCB design, component types, assembly technology and customer specifications.
Step 1: Engineering Review and DFM Analysis
We review your Gerber files, BOM and assembly data to identify potential manufacturing issues before production.
- Gerber and BOM verification
- Component footprint and polarity checks
- DFM analysis and process planning
Step 2: PCB Manufacturing and Component Sourcing
We coordinate PCB manufacturing and electronic component sourcing according to your approved specifications and BOM.
- PCB manufacturing to specified requirements
- Component sourcing and availability checks
- Turnkey or customer-supplied components
Step 3:Material Verification & Preparation
Before PCB assembly begins, materials and production files are checked to ensure the correct components and specifications are used.
- Incoming material verification
- Component and feeder preparation
- Production data confirmation
Step 4:SMT Assembly & Reflow Soldering
Automated SMT equipment places surface-mount components accurately, followed by controlled reflow soldering to form reliable solder joints.
- Solder paste printing and SPI
- Automated component placement
- Controlled reflow soldering
Step 5:THT Assembly & Mixed Technology
For boards requiring through-hole components, we arrange the appropriate insertion and machine soldering processes according to the PCB design.
- Component insertion and orientation checks
- Wave or selective soldering, where applicable
- SMT and THT process coordination
Step 6:PCB Assembly Inspection & Testing
Inspection and testing methods are selected according to the product design and customer requirements to help verify assembly quality.
- 3D AOI and X-ray inspection
- ICT and functional testing, where applicable
- Solder joint and assembly quality checks
Step 7:Final Inspection, Packaging & Delivery
Completed PCB assemblies undergo final checks before protective packaging and shipment according to the agreed requirements.
- Final appearance and quantity checks
- ESD-protective packaging, where required
- Shipment coordination and documentation
