Step 1: Circuit Design
Our engineering team emphasizes quality control from the very first step. They need to make sure the designed power supply satisfied customers’ function requirements, lifetime requirements, and safety(certification) requirements such as UL, CE, KC, and PSE……
Power supplies used for different products got different Quality and Certification requirements. For example, products destined for the EU must comply with CE certification standards.
Step 2: Material Sourcing
All incoming components and designs must fit the safety requirements so that we can get the required different Certifications for different markets from different Institutions.
Step 3: Incoming Inspection and PCB Assembly
All components will be inspected by our quality team, and we will start to assemble the pcb boards with components. Assembly includes SMT, DIP, reflowing, and case assembly, every step is important for a good quality power supply.
Step 4: Comprehensive testing
- load power
- rate current
- rate voltage
- circuit connecting
Step 5: Aging testing
- testing function during a long time working environment
- if function changed during the high temperature
Step 6: Function and safety testing
- after the aging testing processing to check if every function is still working well
- high voltage testing
- current protection, voltage protection…
Step 7: Packing
Each unit is securely packaged to ensure safe delivery to our customers.
