1. Pre-Sales: Needs Diagnosis & Solution Pre-Development​

• In-Depth Requirement Analysis:
  • Through technical workshops and scenario surveys, we accurately understand client needs for temperature tolerance (-55°C to +125°C wide temperature range), interface specifications, security features (intelligent data destruction, power failure protection), and industry standards (industrial automation, defense, etc.).​
• Customized Solution Design:
  • Leveraging our NUW storage technology platform, we provide standardized product recommendations or ODM/OEM tailored solutions, including performance parameters, application scenario analysis, and cost-optimization proposals.​
• Sample Testing Support:
  • Swiftly respond to sample requests with industrial/military-grade product testing, enabling clients to validate compatibility and reliability in target environments (e.g., high-temperature, vibration, high-load scenarios).​

2. In-Sales: Efficient Development & Process Collaboration​

• Full-Cycle ODM/OEM Customization:​
  • From chip-level component selection to hardware architecture design (e.g., special interface development, wide-temperature circuit optimization), we match clients' device requirements for physical dimensions, power consumption, and data security levels.​
  • Offer sample prototyping, low-volume trial production, and mass-production process optimization, reducing product development cycles by over 30% compared to industry averages.​
• Transparent Production Process:
  • Provide real-time updates on production progress and support video monitoring for critical processes (e.g., wide-temperature aging tests, security function verification), ensuring compliance with international reliability standards like IEC 60068-2.​

3. After-Sales: Continuous Support & Value Extension​

• Multi-Dimensional Technical Support:​
  • 7×24-hour remote response for installation, firmware upgrades, and fault troubleshooting.​
  • On-site technical support and data security audits for high-security sectors like defense and military.​
• Tailored Training Programs:​
  • Deliver product operation manuals, hardware adaptation guides, and industry-specific solution training for client teams.​
  • Offer customized technical courses and case studies for complex scenarios (e.g., aerospace storage architecture design).​
• Full-Lifecycle Quality Assurance:​
  • Provide 3-5 year warranties (model-dependent) covering free repair/replacement for non-human damage.​
  • Conduct regular follow-ups to collect feedback, driving performance iterations (e.g., lifespan optimization in wide-temperature environments).​

4. Industry-Tailored Value-Added Services​

• Design embedded storage solutions for industrial automation clients to enhance production line data collection efficiency.​
• Assist automotive electronics clients with AEC-Q100 certification to accelerate the launch of automotive-grade storage products.​
• Develop customized data destruction solutions for defense and military clients, meeting military information security standards like GJB 4966.​

Guided by the philosophy that "service is an extension of products," we integrate technical expertise with service excellence to help clients reduce development costs, shorten time-to-market, and evolve from "product delivery" to "value delivery."

Our team is the heart of our success.  We have partnered with universities to establish an industry-university research base.  This base, covering an area of around 2000 square meters, is made up of four distinct engineering and technology laboratories.  The technical team within the base is mainly composed of leading experts in Taiwan's semiconductor memory technology domain and experienced professionals.  Comprising 36 engineers, each with an average of 15 years of experience in semiconductor technology, and graduates from top-tier universities, the technical team plays a crucial role in driving innovation.

In addition, our 30-member collaborative development team actively contributes to the overall R & D efforts.  The labs at the base have invited experts and professors to provide essential technical guidance and support.  All testing and verification procedures are carried out strictly according to the GJB150A - 2009 and GBT36355 - 2018 standards.  This ensures that our products meet high - quality requirements and can be trusted by our customers worldwide.
