Workflow
We introduce the product development workflow of UNIFIVE's AC adapter and switching power supply. We receive high praise from design to prototype, mass production, quality inspection, and solid after-sales service. Approximately 1500 kinds of models annually are shipped, and it is over 15,000 units.
1. Market research/introduction of new models
In our daily sales activities, we primarily focus on collecting trend information about power supplies that our customers need through thorough hearing. Additionally, we obtain roadmap information on updates and new regulations regarding safety standards, environmental norms, and energy-saving regulations from certification bodies and other sources.
Considering customer trends and the initiation dates of new standards in various countries, we aim to respond to our customers' requests by developing and launching new products at the most opportune times.
2. Design
After confirming the details of the information of equipment used by the customer's power supply, usage method, selling place, necessary safety standards, energy regulation, desired specification, etc., at our sales staff, From the lineup of more than 1,500 kinds of our company, we will select the model closest to your request and recommend it.
If you need to change the details according to your internal standard, you can adjust the design, performance, material, etc., according to your wishes. We also perform substitute work to acquire safety standards with the power supply alone. Especially in terms of electrical performance, we also provide empirical measurement data after tuning up to the customer's desired performance.
We will provide data acquired by a specialized laboratory certified regarding noise, etc., and the laws of each country.
3. Design inspection mass production prototype
For newly developed products, after completion of technical prototyping, we conduct demonstration experiments to ensure that performance is satisfied based on design inspection by the quality control department.
In general, we will provide you samples in quantities appropriate to the trial production stage after submitting several initial samples.
4. Mass production
The trial production conference is held at the end of the mass production prototype. Regarding problems proposed at the meeting, we will prevent trendy failure phenomena and yield deterioration as reflected in mass-produced products.
5. Quality inspection
We perform acceptance inspection of parts (IQC),2.process inspection (IPQC), and shipment inspection (OQC).
Parts acceptance inspection (IQC)
Acceptance inspection and inspection of hazardous substances are performed using the extraction method for all parts except for some packaging parts.
Process inspection (IPQC)
"Is it being produced based on specifications? "Is ultrasonic welding indeed done? "Is the work done according to the work instructions? "Etc. are checked and inspected for all production lots.
Shipping inspection (OQC)
We inspect electric characteristics based on requirements of safety standards and specifications for all production lots. The following standards are applied to acceptance inspection and shipping inspection.
- ANSI / ASQ standard Z1.4 level - Ⅱ
- Critical faults: AQL 0.1% (0/1 judgment)
- Serious defect: AQL 0.1% (0/1 judgment)
- Minor defects: AQL 0.65% (Ac / Re criteria are based on the sampling standard list)
6. After-sales service
In case of trouble, defective products are analyzed. We identify the cause of the occurrence and the cause of the outflow and prevent similar problems by promptly implementing occurrence and outflow prevention measures.
