Product development workflow

UNIFIVE's Products development process is introduced. We receive high evaluation for our comprehensive services from design, prototyping, mass production, and quality inspection, to reliable after-sales support. UNIFIVE is a manufacturer of flexible AC/DC Power Adapters — Desktop & Wall-Mount and switching power supplies, shipping approximately 15,000 units of around 1,500 sample models annually.

1. Market Research and New Product Introduction

Our company collects information on power supply trends needed by our customers mainly through interviews during daily sales activities. We also obtain roadmap information on updates and new implementations of national safety standards, environmental regulations, and energy-saving policies from certification bodies and similar organizations.

We plan the development and market launch of new products at the optimal timing based on customer needs and the start time of new regulations in various countries.

2. Design

After confirming detailed information with our sales representatives, including devices using the power supply, usage methods, sales destinations, required safety standards, energy regulations, and desired specifications, we recommend the most suitable model from our lineup of over 1,500 types.

If further customization is required according to the customer's internal standards, modifications in design, performance, materials, etc., can be made to meet the request. We also offer services for acquiring safety certifications for standalone power supplies. In terms of electrical performance, we provide verified measurement data after tuning according to the requested performance. For noise and other regulatory data, we provide certified lab results.

3. Design Inspection and Mass Production Prototyping

For newly developed products, we conduct design inspections by the quality control department after completion of the initial technical prototype, followed by performance verification tests.

Usually, a few initial samples are submitted, and then more samples are provided according to the prototype stage.

4. Mass Production

At the end of the technical and pre-production prototype stages, we hold production meetings. Issues raised in these meetings are reflected in the final mass-produced items to prevent common defects and yield declines.

5. Quality Inspection

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

Incoming Quality Control (IQC)

Except for some packaging parts, all components undergo sampling inspections and hazardous substance testing.

In-Process Quality Control (IPQC)

We verify and inspect all production lots for aspects such as "Whether production is based on specifications", "Whether ultrasonic welding is properly executed", and "Whether work is done according to instructions".

Outgoing Quality Control (OQC)

We conduct sampling inspections on all production lots based on safety standard requirements and specification-defined electrical characteristics. The following standards are applied to incoming and outgoing inspections:

6. After-Sales Service

In case of any defects, we perform a failure analysis. We determine the cause of occurrence and leakage, promptly implement corrective measures, and prevent recurrence of similar issues.
