Q
Why power amplifier need to aging test?
A
During the processing of electronic products, various defects will be introduced due to the complex processing and extensive use of component materials (even if the design is more better). Whether it is a processing defect or a component defect, it can be divided into obvious defects and potential defects. 

Obvious defects are those defects that cause the product to fail to work properly, such as short circuit/open circuit. 
Potential defects cause the product to be temporarily used, but the defects will be quickly exposed and the product will not work properly. 

That's why need aging test, it can fully expose some deficiencies in the product, including device quality, welding quality and so on. 
Our factory have a aging test 8-10 hours before packing, ensure the quality of the product is qualified before packing.
