Green Product Management

Unimicron is committed to the implementation of green product management with the three principles of “compliance with green specifications and requirements”, “green procurement”, and “green supply chain”, and sets the quality target of HSF. The use of environmentally hazardous substances on products is strictly prohibited, which considers green materials in the process design. The purchased raw materials comply with the requirements of international laws and regulations such as the Restriction of Hazardous Substances Directive (RoHS), Registration, Evaluation, Authorization, and Restriction of Chemical (REACH), Directive of Packaging and Packaging Waste, China RoHS, California Proposition 65, Montreal Convention, etc. 100% products comply with the requirements of RoHS and REACH. The principles of green products and continuous improvement are implemented, to satisfy customers and comply with the requirements for green materials by international environmental protection regulations and fulfill the social responsibility of environmental protection.

Green Material Committee

Unimicron is the second largest professional PCB and carrier board manufacturer in the world in terms of revenue. In order to comply with customer requirements and international laws and regulations, we have established a Green Material Committee in the Printed Circuit Board and Carrier Board Division, which integrates the departments of quality management, materials, products, R&D, manufacturing, and business. Green materials are taken into consideration in the process design, and harmful substances are fully controlled in four major processes, including quality planning, supply chain and material flow, manufacturing, and quality assurance. Internal operations are carried out, and the status and requirements the Company's green products is continuously confirmed through the QC080000 management system. In the event of changes or amendments to customers’ specifications or international regulations, we will conduct internal evaluations, adjust control standards and operating modes, and notify the relevant units by way of announcements to ensure that products meet customer requirements and comply with relevant laws and regulations and green product regulations, to meet quality requirements and customer satisfaction.

HSF Quality Policy

To implement the four major principles of HSF quality policy, Unimicron has established various indicators to regularly track performance and achievement rates, to ensure that the policies are implemented and meet customer needs. From 2013 to 2022, the achievement rate of all HSF quality indicators was 100%, and there were no returns from customers due to HSF non-compliance.

HSF Quality Indicators and Performance

Hazardous Substances Management

All raw materials, packaging materials and chemicals required in the manufacturing process of products are incorporated into the management system to achieve comprehensive management. In order to fulfill our responsibility and contribution as a global citizen, we are committed to not using banned environmental management substances, while complying with the current laws and regulations, meeting the needs of our customers, and protecting the global environment to reduce the impact on the ecosystem. We established measures for source, process, and finished product management to comply with international standards and customer requirements for controlled substances, and to curb the environmental and social hazards caused by the life cycle of our products.

1.Source Management

To implement the source management of green products, Unimicron has developed a complete internal control process and operation regulations for hazardous substances, established a raw material audit mechanism, adopted the E-Pr system for management, and required suppliers to provide third-party testing reports and updates annually. We published the green procurement requirements and conflict minerals investigation form. Also, request suppliers to confirm/reply with a non-use (banned and restricted substances) guarantee letter and conflict-free minerals. Materials are required to comply with EU regulations such as RoHS, REACH, halogen-free, conflict-free minerals, etc., and listed in the Qualified Materials List after passing Unimicron's internal audit. If there are specific requirements by the customer, we will comply with the customer's control standards and supplier management regulations to fulfill our commitment to "100% compliance with international regulations, industry standards and customer requirements for green products".

Review Process

Raw Material Survey

“100% Green Products in accordance with International Regulations, Industry Standards, and Customer Requirements” is Unimicron's commitment to green products. In order to comply with the requirements of the RoHS and REACH, Unimicron carried source and finished product management according to the specifications of the management systems and requested suppliers to survey hazardous substances to ensure that the raw materials were complied with the hazardous substances by RoHS and REACH. In 2022, there were 1,358 RoHS reports from Taiwan facilities for managing and reviewing suppliers, including 574 for direct materials, 638 for indirect materials, and 146 for packaging materials, which were 100% completed.

Hazardous Substance Control

In order to promote green product management and product safety, Unimicron's products are currently banned to use environmentally hazardous substances, and in accordance with EU regulations (e.g. RoHS, REACH, IEC 62474, etc.), a total of 1,140 substances are listed in 11 regulatory directives and customer-specific requirements, including GADSL (274 substances) and Prop65 (970 substances), which are mainly published on the official website of the regulations.

Unimicron’s products are one of the components of complex electronic products, and the most important concern for customers is the EU REACH SVHC and RoHS hazardous substances restriction directive. Unimicron’s products give priority to green materials that comply with regulations and customer requirements. Except for customer-specified materials, there are two main hazardous substances in products, including brominated flame retardants and bisphenol A. The content ratio of 4.37% based on the total sales amount of the products, corresponds to the material declaration limit value of IEC 62474 for electrical and electronic products..

Hazardous Substance Survey

Unimicron is disclosing hazardous substances to its customers by means of supplier hazardous substance surveys. After informing suppliers of the new hazardous substance control items, Unimicron requires suppliers to provide a letter of assurance of non-use of banned and restricted substances and a declaration of REACH compliance to ensure compliance with the law and Unimicron's regulations, and to keep track of the use of all materials containing banned and restricted substances and SVHCs. According to the customer's material number that uses SVHC, we reply to the customer survey form and implement source management. In 2022, we cooperated with customers in the investigation of hazardous substances of PCB and Carrier SBU in Taiwan, we conducted a total of 387 supplier surveys, with a response rate of 100%, and completed a total of 818 surveys of hazardous substances required by customers, with a completion rate of 100%.

2.Process Management

• Test incoming materials and products for Hazardous substances by XRF analyzer. There are 6 XRF analyzers to control the Hazardous Substances of incoming materials, products and package materials.
• "Halogen-free" and "lead-free" are used for the entire production process unless specified by the customer.
• Identify and manage customers' specified materials from incoming materials, receiving materials, and manufacturing to warehousing of finished products.
