Products Development Workflow

UNIFIVE's Products development process is introduced here. From design and prototyping to mass production, quality inspection, and reliable after-sales service, we have earned high praise. UNIFIVE, as a manufacturer of flexible AC/DC Power Adapter and switching power supplies, ships approximately 15,000 units annually across about 1,500 sample models each year.

目次

1. Market Research Introduction of New Models

Our company collects trend information on power supplies required by customers, mainly through daily sales activities and hearings. We also obtain roadmap information regarding updates and new establishments of safety standards, environmental standards, and energy-saving regulations in various countries from certification bodies and other organizations.

While considering customer trends and the timing of new regulations in each country, we develop and introduce new Products to the market at the optimal time to meet customer needs.

2. Design

Our sales representatives first confirm detailed information such as the equipment in which the power supply will be used, usage methods, sales destinations, required safety standards, energy regulations, and desired specifications. We then select and recommend the model closest to your requirements from our lineup of over 1,500 types.

If further modifications are required in accordance with your in-house standards, we can accommodate changes in design, performance, materials, and other aspects to meet your needs. We also provide support for obtaining safety certifications for the power supply unit itself upon request. In particular, regarding electrical performance, we provide verified measurement data after tuning the product to meet your required specifications. For noise and other regulatory requirements in various countries, we provide data obtained from certified laboratories.

3. Design Inspection Mass Production Prototyping

For newly developed products, after completion of technical prototypes, the Quality Control Department conducts design inspections and verification tests to ensure that performance requirements are fully satisfied.

We typically provide several initial samples to customers, followed by additional samples in quantities appropriate to each prototyping stage.

4. Mass Production

Prototype review meetings are held at the completion of technical prototyping and again at the completion of mass production prototyping. Issues identified during these meetings are reflected in the mass-produced products to prevent recurring defects and yield deterioration.

5. Quality Inspection

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

Incoming Quality Control (IQC)

All components, except for certain packaging materials, are subject to sampling inspections upon receipt, including testing for hazardous substances.

In-Process Quality Control (IPQC)

For all production lots, we verify and inspect whether products are manufactured according to specifications, whether ultrasonic welding is properly performed, and whether operations follow work instructions.

Outgoing Quality Control (OQC)

For all production lots, we conduct sampling inspections of electrical characteristics based on safety standard requirements and specification documents. The following criteria are applied to incoming and outgoing inspections:

6. After-Sales Service

In the event of a defect, we conduct a thorough failure analysis. After identifying the root cause and the cause of outflow, we promptly implement measures to prevent recurrence and prevent similar issues from occurring again.
