Expert Shenzhen electronics sourcing agent with PCBA engineering support

As a specialized Shenzhen electronics sourcing agent with PCBA engineering support, we handle all types of PCB assemblies:

• Through-Hole Technology (THT) PCBA for industrial applications
• Surface Mount Technology (SMT) PCBA for consumer electronics
• Mixed Technology (THT+SMT) PCBA for complex devices
• Flexible and Rigid-Flex PCBA for wearable and compact devices
• High-Density Interconnect (HDI) PCBA for high-performance electronics
• Metal Core PCB (MCPCB) for LED and high-power applications
• RF and High-Frequency PCBA for communication devices

Our engineering team in Shenzhen has expertise in designing and manufacturing PCBA for consumer, industrial, medical, automotive and IoT applications.

Our Shenzhen electronics sourcing agent with PCBA engineering support fees are transparent and project-based:

• Small projects (prototyping <100 units): 8-10% of total PCBA cost
• Medium production (100-10,000 units): 5-7% of total PCBA cost
• Large production (10,000+ units): 3-5% of total PCBA cost
• Engineering support only: $100-$180/hour (Shenzhen-based engineers)
• Quality inspection only: $250-$500 per factory audit in Shenzhen

Our fees are offset by the 25-40% cost savings we achieve through direct Shenzhen factory pricing and engineering optimization, making our service cost-neutral or profitable for most clients.

Yes - engineering support for existing designs is a core part of our Shenzhen electronics sourcing agent with PCBA engineering support service:

• Design review and manufacturability analysis (DFM) for Shenzhen production
• Component substitution for cost reduction or availability issues
• Design optimization for better performance or reliability
• Troubleshooting and root cause analysis for production issues
• Redesign for certification compliance (CE, FCC, ROHS)
• Engineering change order (ECO) management during production

Our team of 15+ electronic engineers in Shenzhen can work with your existing CAD files (Altium, Eagle, KiCad) to optimize your PCBA design for manufacturing in Shenzhen.

As your Shenzhen electronics sourcing agent with PCBA engineering support, we manage production timelines efficiently:

• Prototyping (1-10 units): 7-14 days from design finalization
• Small batch production (10-100 units): 14-21 days
• Medium production (100-1,000 units): 21-28 days
• Large production (1,000+ units): 28-45 days
• Rush production (urgent orders): 5-10 days (premium fee applies)

Lead times include component sourcing, PCB fabrication, assembly, testing and quality inspection in Shenzhen. Shipping adds 5-10 days for air freight or 25-40 days for sea freight to most destinations.

Quality and authenticity are paramount to our Shenzhen electronics sourcing agent with PCBA engineering support service:

• Only source components from authorized distributors and franchised suppliers in Shenzhen
• Component authentication via laser marking verification and batch code checking
• Incoming quality control (IQC) for all components before assembly
• Automated Optical Inspection (AOI) for all PCBA after soldering
• X-ray inspection for BGA and hidden solder joints
• Functional testing (FCT) against your specifications
• Random sample testing by our independent quality lab in Shenzhen

We provide full traceability documentation for all components and PCBA produced, including COC (Certificate of Conformity) and material certificates.
