Core values

1

Cautious leadership

At WJW, we are a collection of people, ideals, successes and failures. So we stand for a lot of things. But at the end of the day, CARE is our core – it’s what brings us together.

2

We can never get too hung up on how we fit in. This doesn’t always mean push forward at all costs. We are curious about how we should evolve and enjoy the process of continuous improvement.

3

Choose fun

Joy on the road is our motto. We take what we do and how we do it seriously, but we have fun along the way.

Our characteristics

Experience the reliability of our products and receive free samples of our USB cables and power adapters. This allows you to confirm the quality and suitability of your customized USB cables and power adapters before placing a bulk order, reducing purchasing risk and ensuring you make the right choice.

We understand the importance of flexibility. Our Minimum Order Quantity (MOQ) allows you to place orders based on actual demand, minimizing inventory waste and reducing the risks of bulk purchasing. This flexibility helps you launch products faster and maintain a competitive edge.

As an ISO 9001:2015 certified factory, we adhere to the highest international standards in every stage of the manufacturing process. This certification guarantees that our USB cables, power adapters, and custom components are produced with high precision and quality, ensuring long-term reliability and customer satisfaction.

Equipment & Technology

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.

1🛒Follow a Regular Equipment Maintenance Plan

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.

2🛩Implement a Secure Database System

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.

3🚄Facilitate Validation Processes

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.

4🎫 Conduct Regular Equipment Calibration Activities

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.

5🎨Facilitate Staff Training

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.
