Solving Your Manufacturing Headaches
Managing PCB fabrication, sourcing, assembly, coating, and testing across multiple vendors creates quoting delays, communication gaps, and avoidable quality risk.
We bring those steps under one manufacturing team.
Supply Chain Security
"Traceable Components Only."
We source exclusively from authorized distributors (Digi-Key, Mouser) or direct manufacturers to prevent counterfeit parts.
Quality Assurance
Strictly Quality Control Process.
Standard AOI & X-Ray inspection included. We offer custom Functional Testing (FCT) to ensure every board works before shipping.
English-Speaking Project Support
No language barriers.
Our project managers and engineers speak fluent English, ensuring your technical requirements are perfectly understood.
Save Time and Coordination Effort
You save time cost & energy.
You get professional PCB assembly, molds, wire harnesses, coating, and packaging managed at one-stop.

Proven Solutions for Complex Challenges
Fragmented Supply Chain & Quality Risks
The client, a brand owner, was managing 5 different suppliers for PCB, components, molding, and assembly. This led to high communication costs, mismatched tolerances, and delayed time-to-market. They needed a partner to centralize the process without compromising quality.
One-Stop Integration
- Consolidated Manufacturing: Handled PCB, PCBA, Cable, and Custom Molding under one roof.
- Strict QC: Implemented custom functional testing for wireless connectivity.
- Result: Reduced total costs by 18% and shortened lead time by 3 weeks.
High-Voltage Reliability & Component Shortages
A solution design house needed low-volume production for high-voltage industrial controls. The design required 10+ layer PCBs and specific EU/US components that were facing global shortages. Reliability was non-negotiable.
Stable Sourcing & Precision 0201 SMT Assembly
- Global Sourcing: Optimized Parts Cost through our 15-year supplier network.
- High-Mix Capability: Delivered 10-layer heavy copper PCBs with zero defects.
- Result: Successfully launched pilot run with 99.8% yield rate.

PCBA Contract Manufacturing FAQs
Q
What files do I need to submit for a PCBA quote?
What files do I need to submit for a PCBA quote?
We require Gerber files (RS-274X format), BOM (Bill of Materials) in Excel/CSV format, and Pick-and-Place (Centroid) files for SMT assembly. For programming and testing requirements, please include test procedures or firmware files. Our DFM team will review your files within 24 hours.
Q
Do you provide component sourcing services?
Do you provide component sourcing services?
Yes, we offer full turnkey component sourcing through our global procurement network. We source exclusively from authorized distributors (Digi-Key, Mouser) or direct manufacturers to prevent counterfeit parts. We also provide BOM kitting, shortage sourcing, and cost-down alternatives for high-volume production.
Q
What is the difference between SMT and THT assembly?
What is the difference between SMT and THT assembly?
SMT (Surface Mount Technology) places components directly onto the PCB surface using pick-and-place machines—ideal for 01005, 0201, BGA, and high-density designs. THT (Through-Hole Technology) inserts leads through drilled holes for stronger mechanical bonds, used for connectors, transformers, and high-power components. We support both technologies in a single assembly process.
Q
What quality control measures do you implement?
What quality control measures do you implement?
Our IATF 16949 and ISO 9001 certified process includes: Automated Optical Inspection (AOI) after SMT, X-Ray inspection for BGA/QFN components, In-Circuit Testing (ICT), and custom Functional Circuit Testing (FCT). We maintain 100% traceability by lot or serial number and offer detailed inspection reports upon request.
Q
Can you handle BGA and high-density components?
Can you handle BGA and high-density components?
Absolutely. We specialize in BGA, FPGA, and 0201/01005 pitch components using Yamaha/Panasonic high-precision pick-and-place machines. Our X-Ray inspection system verifies BGA solder joint integrity, and we support microvias down to 0.075mm for HDI applications. Lead-free and halogen-free processes are available.
Q
What is the typical lead time for PCBA production?
What is the typical lead time for PCBA production?
Prototype (1-50 pcs): 10-15 working days.
Low Volume (50-500 pcs): 10-15 working days.
High Volume (500+ pcs): 3-4 weeks depending on component availability.
We provide 24-hour quotes and DFM feedback to accelerate your time-to-market.
