Most people think the power supply is a small part of electronic devices or equipment, not a big deal, but I must say “you were wrong”, it is extremely important for your electronics. Power supplies are devices that supply power to electric loads, without it your electronics won’t work, with a bad power supply or short lifetime power may hurt your electronics, this is why it’s so important and why we need to talk about the Quality Control for power supplies.
What is Quality Control?
.
A process through which a business seeks to ensure that product quality is maintained or improved is quality control, which is performed on products throughout the manufacturing process, from incoming inspection to final inspection and test. It requires the company to create an environment in which both management and employees strive for perfection. So there are some standard processing and certification were made according to some common requirements, and some organizations were established to inspect the company’s quality control processing.
When we talk about Quality Control, we are not only mean quality control, but the whole process includes quality system, quality assurance, and quality control.
The essential Quality Control for power supply manufacturing.
Quality Management System
Common quality management system
- ISO9001: a set of standards that helps organizations ensure they meet customer and market needs within statutory and regulatory requirements related to a product or service.
- https://en.wikipedia.org/wiki/ISO_9000
- ISO/IEC17025: used by testing and calibration laboratories.
- https://en.wikipedia.org/wiki/ISO/IEC_17025
- ISO13485: requirements for regulatory purposes is a voluntary standard for Medical devices.
- https://en.wikipedia.org/wiki/ISO_13485
- IATF 16949: technical specification aimed at the development of a quality management system automotive industry
- https://en.wikipedia.org/wiki/IATF_16949
Quality Management System needed for power supply industry
According to quality management system and market requirements, ISO9001 is suitable for power supply manufacturers.
Quality Assurance for power supply products.
As society and the economy develop, there are some authoritative bodies that provide official testing and certifications for companies, those certifications will help the manufacturers to prove that their products are with quality assurance and satisfied the official standard and specific market requirements. There are some common safety certifications for power supply products for different markets.
The Common Certifications
- UL: North and South America
- CE: European Countries
- PSE: Japan
- UKCA: United Kingdom
- KC: South Korea
- CB: Argentina, Austria, Australia, Belarus, Belgium, Brazil, Canada, China, Czech Republic, Germany, Denmark, Spain, Finland, France, United Kingdom, Greece, Hungary, Slovenia, Norway, India, Israel, Italy, Poland, Singapore, Portugal, Russia, Slovakia, Romania, Singapore, Slovakia, Slovenia, South Africa, Turkey, Ukraine, Korea, USA, Mexico, Yugoslavia, Switzerland, New Zealand, Malaysia, Sweden, Japan, Thailand.

The Authoritative Organizations
Accredited Certification Provides Confidence to End Users, Choose some famous organizations to do the certification is better for getting the confidence of customers.
Quality control processing for power supply manufacturing
To ensure all products DC/AC Power Supply and related products with reliable quality, the manufacturers must always follow ISO9001 quality management system to do the QC quality control during every step of the whole manufacturing process to provide qualified Power Supplies and Power Quality products to customers.
Processing related to Quality Control
- Step1: Material Sourcing
- Step2: Incoming Inspection
- Step3: Intermediate Inspection and testing
- Step4: PCB board reliability testing
- Step5: Aging testing
- Step6: Function testing
- Step7: Product reliability testing
What needs to do to control quality during the manufacturing
- Personnel: Hire qualified employees and train them.
- Material control: take care of material souring and set QC for incoming inspection.
- Intermediate Inspection and testing: sampling inspection and testing during the PCB assembly.
- PCB board reliability testing: AOI and personnel inspection for every PCB board.
- Aging testing: this is a must for power supply-related products.
- Function testing: check if every function is still working well, including current protection, voltage protection, and high voltage testing
- Products reliability testing: pull for cable connection and drop for case reliability……
