PCB Fabrication
High-Precision Board Manufacturing We manufacture PCBs according to the customer's design files and technical requirements, supporting advanced multilayer structures, fine-line processing, and impedance-controlled layouts to ensure electrical integrity and manufacturability.
Key Processes:
- Multilayer fabrication (up to 14 layers)
- Fine line/spacing and microvias
- HDI, blind/buried vias, via-in-pad
- Impedance control and custom stack-ups
- Special materials, finishes, and edge plating
- 100% electrical testing
PCB Assembly
SMT, THT & Mixed-Technology Assembly Components are assembled using automated SMT lines and THT processes based on production volume and design complexity. Both lead-free and leaded soldering are supported, with controlled reflow profiles for quality consistency.
Key Processes:
- SMT, THT, and mixed assembly
- BGA, QFN, QFP, Micro-BGA, POP packages
- Reflow soldering & wave soldering
- AOI, X-ray, ICT inspection
- Custom reflow profiles and high-density assembly
Parts Management
Component Sourcing, Verification & Inventory Control All components are sourced, verified, and managed through a structured procurement and quality control system to ensure authenticity, availability, and cost efficiency.
Key Processes:
- Turnkey component sourcing
- Rare/EOL component procurement
- BOM analysis, cross-referencing & substitution
- Incoming inspection & electrical verification
- Inventory management and kitting
- 24-hour BOM pricing
Functional Testing
Electrical, Functional & Environmental Validation Each assembled board is tested according to customer-defined test plans to verify electrical performance, functional behavior, and environmental reliability.
Key Processes:
- AOI, X-ray, ICT, FCT
- Embedded system testing
- Custom test software
- Signal integrity, I/O, power validation
- High/low temperature & humidity testing
- Vibration, shock, and drop testing
IC Programming
Secure Device Programming & Data Verification ICs are programmed before or after assembly based on project requirements, with strict data security and verification to ensure firmware accuracy and IP protection.
Key Processes:

How Our Online PCB Assembly Works
Upload your Gerber files for PCB fabrication so we can produce bare boards to your specifications.
Submit your BOM and CPL / Pick-and-Place files to define components and placement.
Validate with our online system, which automatically reviews your files and flags potential issues before production.
Check with integrated DFM & DFA analysis to catch footprint mismatches, polarity risks, or spacing concerns early-saving time and cost.
