Quality Management Certifications
Quality is embedded in every stage of our PCB assembly and EMS manufacturing process.
Our manufacturing, inspection, and testing processes are aligned with internationally recognized quality management systems and industry
standards. Supported by ISO-certified management systems and controlled production processes, we focus on consistency, traceability, and
risk-controlled manufacturing for regulated and high-reliability applications.
Supported by ISO-certified management systems and rigorous process controls, our manufacturing processes are designed to consistently
meet customer requirements and applicable regulatory expectations.
Specific acceptance criteria, inspection levels, and quality requirements are defined, documented, and agreed upon with customers
on a project-by-project basis.
Inspection & Testing Capabilities
Inspection & Testing Capabilities
Inspection and testing methods such as Automated Optical Inspection (AOI), X-ray inspection, and Functional Circuit Testing (FCT) are applied based
on project requirements, product characteristics, and customer-defined quality criteria.
These inspection and testing activities support defect detection, process verification, and quality monitoring throughout production, rather than
representing a guarantee of defect-free products.
Inspection coverage, sampling plans, and test depth are determined according to customer specifications, applicable standards, and risk assessments.
• ISO 9001 — Quality Management System
Certified quality management processes designed to support consistent manufacturing, inspection, and continuous improvement.
• ISO 13485 — Medical Devices Quality Management System
Supporting electronics manufacturing for medical devices and regulated applications with strict traceability and risk management controls.
• ISO 14001 — Environmental Management System
Demonstrating commitment to environmentally responsible manufacturing practices and regulatory compliance.
• RoHS / REACH — EU Environmental Compliance
Compliance with EU directives restricting hazardous substances and ensuring safe use of chemicals throughout the supply chain.
• IPC Standards — IPC-A-610, IPC-7711/7721
Manufacturing and rework processes conducted in accordance with IPC workmanship, acceptance, and rework standards for electronic assemblies.
Acceptance criteria can be applied based on customer-specified IPC class requirements.

Quality Control Process
Quality Control Process
• IQC (Incoming Quality Control) —
Incoming inspection and verification of all components and materials
prior to production.
• IPQC (In-Process Quality Control) —
Continuous in-process monitoring and quality checks during SMT / THT
assembly to ensure process stability.
• 100% AOI Inspection —
Automated Optical Inspection applied to all PCBs to detect component,
placement, and soldering defects.
• X-ray Inspection —
Non-destructive inspection for BGA and other hidden solder joints,
including internal solder quality evaluation.
• Functional Testing (FCT) —
Functional and performance testing to verify product operation
based on customer specifications.
• OQC (Outgoing Quality Control) —
Final inspection and verification prior to shipment to ensure
products meet approved quality requirements.
Our Commitment to Quality, Compliance & Manufacturing Excellence
Our Commitment to Quality, Compliance & Manufacturing Excellence
• Full compliance with customer specifications, IPC standards (IPC-A-610 / IPC-7711/7721), and regulatory requirements
We strictly follow defined acceptance criteria, documentation control procedures, and full traceability systems for every PCB assembly project.
• Continuous improvement through process optimization and data-driven quality control
Ongoing SPC monitoring, root cause analysis (RCA), corrective and preventive actions (CAPA), and internal audits strengthen manufacturing stability.
• Reliable, on-time delivery supported by controlled production systems
Integrated in-house SMT, THT (DIP), AOI, X-ray, ICT, and FCT capabilities ensure stable output from prototype builds to volume PCB assembly production.
• Transparent and auditable manufacturing environment
Factory audits, documentation reviews, and on-site visits are welcome by appointment.
