"DC Fan" PCB board mounted HALL IC and other components, it is one of the main components of the fan section. HALL IC standing welding, this welding method is not generally used in less than 5cm a big fan, IC is directly sensitive to the inner surface of the magnetic stripe, the magnetic stripe and the inner side of the magnetic field strength is the strongest, the more beneficial Sensor induction so standing welding distance IC and magnetic stripe less stringent requirements. Failure phenomenon (bad sensor, dead, poor waveform, wave size, etc.) less. HALL IC flat stick welding, this welding method is generally used in less than 5cm fan, since the IC is induced magnetic stripe below the inside of the magnetic field, the magnetic field density here is relatively weak, it is generally flat against the welding induced adverse phenomenon is more many.
