About Quality
Driven by our commitment to enhancing the quality of automotive electronic products, Wellysun continuously improves production equipment, quality systems, manufacturing processes, product validation, and component procurement. We ensure compliance with automotive-grade production standards, leveraging automated production lines and high-spec manufacturing environments.

IATF 16949 Certification
Automotive-Grade Production and Manufacturing
We follow to the technical specifications of global automotive quality systems, integrating quality requirements across international automotive industries. This standard incorporates essential elements such as production approval procedures, continuous improvement, manufacturing capabilities, and customer-specific requirements.
AUTOMOTIVE SPICE
Quality Assurance
ASPICE ensures high standards in software design, development, and testing, reducing errors and enhancing product reliability.
Supply Chain Collaboration
As a universal automotive standard, ASPICE strengthens communication and collaboration between OEMs and suppliers.
Meeting Market Demands
ASPICE is a critical benchmark for entering the global automotive market, regarded by leading automakers as a key supplier evaluation standard.



ISO 9001/14001
ISO 9001 helps organizations reduce costs, increase profits, gain more business, and meet customer expectations across all scales.
ISO 14001 assists organizations in minimizing their environmental impact while driving business growth.

ISO 13485
ISO 13485 is an internationally recognized quality management standard tailored for the medical device industry, ensuring high-quality products for global medical clients while reducing the need for multiple quality system certifications in the sector.

Regulations and Product Requirements
We cater to export markets, including Europe, the U.S., and Japan, by ensuring that electronic modules meet the safety standards and regulations of target markets. This includes compliance with electrical safety laws and the chemical substance management and registration requirements of supply chains.

Digitalized Manufacturing Control | MES Manufacturing Execution System
From order receipt, production, process control, to product completion, we collect and monitor production data. Using relational databases, graphical user interfaces, and open architecture, we transmit real-time production information to users for monitoring. In case of emergencies, the system provides real-time information to improve processes and increase production efficiency.

Stringent Production Environment Standards | 5S/6S Environment Management
Implementing the 5S/6S management method enhances workplace environment quality and employee mindset, targeting comprehensive quality management. Activities are conducted on production materials, equipment, and personnel to lower costs, ensure timely delivery, safe production, standardization, and continuous improvement.

Chemical Substance Certification and Investigation | RoHS, REACH, IMDS, chemSHERPA
In line with customer product requirements, we conduct investigations into the chemical substance information transmission standard systems currently used in the electronics industry. We collect, organize, and register data from upstream suppliers to meet compliance and pass this information to customer systems.
Factory Production Line Insights






MES Manufacturing Execution System
Real-time monitoring of equipment, raw materials, and work-in-progress status in factories. Work plans are created based on production schedules, guiding production line personnel with relevant information, and collecting and managing production data.
Independent Electronics-Specific Warehousing
Electronic components must be stored in clean, ventilated warehouses free of corrosive gases, with controlled temperature and relative humidity. Moisture-sensitive components also require additional management and storage.
Regular Audits and Quality Improvement Activities
In addition to audits from quality systems and customers, the internal team conducts quality education and continuous improvement activities. Improvement projects are tracked and rectified persistently.
Dust-Free Production Workshops
Production lines are equipped with dust-free environments to meet cleanliness requirements. As components become smaller, environmental particles can significantly impact product quality.
Electrostatic Discharge (ESD) Protection
Static electricity generated during production may damage devices and circuits. ESD protection measures safeguard products and components, ensuring stable quality.
Full-Area Cleanroom Management
The cleanliness of the production environment is crucial to production quality. Full-area cleanroom management is implemented to maintain high factory standards and avoid potential impacts on product quality.
