Quality Control Laboratory
Our laboratory is not just a process, it is a key
Our product lab goes far beyond standard testing procedures; it’s an incubator for innovation and a guardian of quality. Here, every power adapter and USB cable undergoes rigorous testing that exceeds industry standards, ensuring that performance, safety, and reliability remain competitive throughout the entire process from design prototype to mass production. With our robust testing, we safeguard your product safety and protect your brand reputation.
Advanced and reliable electronic test equipment
The company is equipped with advanced electronic testing equipment, including CHROMA series, FLUKE, YOKOGAWA, and TESEQ systems, ensuring all products meet international standards. Key testing capabilities include: • Electrical safety tests (Hi-pot, continuity, lightning strike) • Environmental tests (temperature chamber, salt spray) • Mechanical tests (tension, cable swing, drop test) All equipment is regularly calibrated to guarantee accuracy.
Strictly enforced test specification requirements
In the laboratory, we implement a set of test specifications in line with the industry and relevant national standards, and the test parameters of various products are divided into levels of requirements for implementation. Testing personnel must be strictly trained and qualified before they are allowed to operate. They need to ensure that all types of instruments are regularly calibrated and tested to guarantee that the data detected in the laboratory meets the standard requirements, to reduce the client’s testing time and costs, and to provide a more effective solution to solve customer needs.

Staff Competence and Training
Laboratory personnel should possess the ability to understand the conditions and requirements of the laboratory environment. The laboratory is responsible for training its staff to ensure they are kept informed of laboratory operating procedures, current quality principles, the latest technological processes, and regulatory requirements. We regularly arrange training for laboratory personnel and organize them to learn relevant electronic knowledge and industry standards. Exchanging ideas with industry professionals and participating in other activities to expand business capabilities is crucial for improving the laboratory’s efficiency and development. Close collaboration with R&D engineers and a deep understanding of each other’s work helps establish a close working relationship, thereby ensuring the validity of experimental results.





Regular equipment maintenance is one of the most effective ways to ensure accurate and reliable laboratory results. Therefore, the laboratory has developed and strictly adheres to a preventative maintenance plan. After each preventative maintenance procedure, all relevant documentation, such as a maintenance checklist, is completed, along with the appropriate authorization and signature.
Laboratory data systems must be secure and reliable, capable of withstanding any hacking attacks or intrusion attempts. Appropriate user levels must be configured and password protection enabled. Furthermore, the system should include audit trails, backups, and disaster recovery.
All these measures maintain and ensure the accuracy and reliability of laboratory results. We are committed to meeting all your requirements for our products.
Ensure all the validation activities are completed with relevant documentation. For example, Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) should be executed before using newly installed equipment.
Calibration is one of the key parameters for regulatory inspections. Calibration demonstrates the accuracy and precision of equipment when performing measurements. Equipment should be calibrated according to a regular calibration schedule, and relevant records, including approvals and signatures, should be properly maintained. All of the above calibration-related tasks can be easily handled using Quality Management System (QMS) software (such as Simpler QMS). This software allows us to manage documentation for each piece of equipment, create tasks and assign them to relevant personnel, and send email notifications when calibration activities are due.
Inspectors will check whether department staff have the ability to perform daily tasks, such as adherence to safety principles, sample handling, and other activities. Laboratory management is responsible for conducting training programs. In this regard, automating training using Quality Management System (QMS) software such as Simpler QMS is a worthwhile investment, as it helps us efficiently manage all aspects from training planning to execution. Training can be easily scheduled based on employee titles and roles. The software can also track training due dates, distribute necessary training materials, and send notifications when new training materials are released. Finally, upon completion of training, the software automatically generates a training certificate with an electronic signature.
