More questions:
1 . What is a DC Axial Fan ?
An DC fan is usually powered by 3v , 5v , 12v , 24v , 36v and 48v . It blows air along the axis of the fan , or parallel to the track of the
blade axis .
Standard DC Axial fan sizes include 20mm , 30mm , 40mm , 50mm , 60mm , 70mm , 80mm , 92mm , 120mm , 150mm , and 200mm .
2 . How to choose a DC fan ?
To choose a DC fan , you should consider the points below
√ fan voltage
√ fan current
√ fan speed
√ fan airflow
√ fan noise
√ fan lifespan
3.What is a bearing ?
Bearing includes Sleeve Bearing and Ball Bearing , life expectancy of sleeve bearing fan is 30000hours , while ball bearing is 50000hours or more
4 . How do we carry out quality control ?
Usually , there are two ways to monitor reliability during the manufacturing process .
⇒ Early Life Test
This is used as a mean of process control determined at identify any latent manufacturing problems and determining the effectiveness of
burn - in . Every day , 5 samples will be picked up from one of the production lines for burn at at 50 ° C + / - 5 ° C for 24 hours .
⇒ On - going Reliability Demonstration
This is a longer - term program at at providing data on continuous basis to demonstrate the reliability of product . 10 units per month are diverse collected from one of the production lines for burn - in for 168 hours at 50 ° C + / - 5 ° C . Units are monitored and tested on daily basis .
Failed units will be analyzed and corrective actions taken where necessary .
