PRODUCT PK
ASEMI adopts 50mil high-quality large chip, with good parameter consistency and stable and efficient output
Inferior chip easy to heat seriously after long-time working , and will damaged the machine
ASEMI uses laser marking is not easy to fade and prevents refurbishment
Inferior and easy to fade will pullute PCB board,and also exist a problem of malicious renovation
ASEMI uses high-purity oxygen-free copper frame and pins, with good electrical conductivity and high strength of thickened pins
Ordinary steel is easy to be oxidize and virtual weld, the strength is low then easy to break
The ASEMI factory uses Jianding and Guankui high-precision equipment to test 18 key electrical data simultaneously
Other equipment has low precision, the electrical parameter detection is not strict, and the quality consistency is poor
APPLICATION
Industrial equipment
Led lamps and lanterns
Induction cooker
Electric welding machine
Power adapter of laptop
