Product development workflow

We present the product development flow of Unifive. From design to prototyping, mass production, quality inspection, and reliable after-sales service, we have received high praise. Unifive ships approximately 15,000 units annually of about 1,500 sample models as a manufacturer of AC/DC Power Adapters — Desktop & Wall-Mount and switching power supplies with flexible support capabilities.

1. Market Research & New Product Introduction

We collect trend information on power supplies required by our customers, mainly through hearings during daily sales activities. We also obtain roadmaps for updates and newly established safety standards, environmental standards, and energy-saving regulations from certification bodies in various countries.

By considering customer trends and the timing of new regulations being implemented in different countries, we develop and introduce new products to the market at the best possible timing to meet our customers' needs.

2. Design

After our sales representatives confirm detailed information from customers, such as the devices using the power supply, methods of use, sales destinations, necessary safety certifications, energy regulations, and desired specifications, we select and recommend the model that best fits the requirements from our lineup of over 1,500 types.

If further customization is required based on the customer's internal standards, we offer modifications in design, performance, materials, etc., according to customer requests. We also handle safety certification acquisition for the power supply unit alone. Especially for electrical performance, we provide actual measurement data after tuning the product to meet the performance required by the customer. For noise and other matters related to legal regulations in each country, we provide certified lab data.

3. Design Inspection & Mass Production Prototyping

For newly developed products, we conduct a design inspection by our quality control department after technical prototyping is completed, followed by validation testing to ensure performance requirements are met.

After providing customers with several initial sample units, we deliver further samples according to the prototyping stage.

4. Mass Production

At the end of technical prototyping and mass production prototyping, we conduct prototype review meetings. Issues raised at the meetings are reflected in the mass production to prevent recurring defects or yield deterioration trends.

5. Quality Inspection

We perform Incoming Quality Control (IQC), In-Process Quality Control (IPQC), and Outgoing Quality Control (OQC).

Incoming Quality Control (IQC)

Except for some packaging parts, we conduct inspection and hazardous substance testing on all components using a sampling method.

In-Process Quality Control (IPQC)

We verify and inspect all production lots, checking whether production is based on specifications, ultrasonic welding is properly done, and work procedures follow the instructions.

Outgoing Quality Control (OQC)

We inspect electrical characteristics based on safety requirements and specifications using a sampling method for all production lots. The following standards are applied for both incoming and outgoing inspections.

6. After-Sales Service

When defects occur, we analyze the defective products to identify the cause and leakage points. We promptly implement measures to prevent recurrence and leakage to ensure similar issues do not occur again.
