Soldering: • • • • Do avoid overheating of the PD Do avoid electrostatic discharge (ESD) Do avoid mechanical stress, shock, and vibration Do only use non-corrosive flux • Do not apply current to the PD until it has cooled down to room temperature after soldering Static Electricity: PDs are sensitive to electrostatic discharge (ESD). Precautions against ESD must be taken when handling or operating these PDs. Surge voltage or electrostatic discharge can result in complete failure of the device. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice www.roithner-laser.com 3
