Samsung recommends a 4-layer PCB with a dedicated ground plane and thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad with a minimum size of 10mm x 10mm is recommended for heat dissipation.
To ensure reliable operation, it's essential to follow the recommended operating conditions, including temperature, voltage, and current. Additionally, consider using thermal protection devices, such as thermistors or thermal fuses, to prevent overheating. It's also recommended to perform thorough testing and validation across the entire operating temperature range.
Samsung recommends using a soldering temperature of 260°C ± 5°C, with a soldering time of 3 seconds ± 1 second. It's also recommended to use a solder with a melting point of 217°C ± 5°C. Additionally, ensure that the PCB is clean and free of oxidation to ensure reliable solder joints.
To handle the high current and power dissipation, it's essential to use a robust PCB design with adequate copper thickness and thermal management. Consider using a heat sink or thermal interface material to improve heat dissipation. Additionally, ensure that the power supply and wiring can handle the high current requirements.
To prevent electrostatic discharge (ESD) damage, it's recommended to use ESD protection devices, such as TVS diodes or ESD protection arrays, on the input and output pins. Additionally, ensure that the PCB design includes adequate ESD protection features, such as ESD protection zones and guard rings.
