Aimtec recommends a PCB layout with a large copper area connected to the module's thermal pad to dissipate heat efficiently. A minimum of 1 oz copper thickness is recommended, and the copper area should be connected to a solid ground plane to reduce thermal resistance.
Aimtec recommends using a soldering profile with a peak temperature of 240°C to 250°C, and a dwell time of 30 seconds to 60 seconds. The module should be soldered using a solder with a melting point of 217°C to 220°C. Additionally, the PCB should be cleaned and free of oxidation before soldering.
Aimtec recommends derating the input voltage by 10% to 15% to ensure reliable operation and to prevent overvoltage stress on the module. This means that if the module is rated for 5V input, the maximum allowable input voltage should be 4.25V to 4.5V.
To troubleshoot output voltage deviations, check the input voltage, output load, and ambient temperature. Ensure that the input voltage is within the recommended range, and the output load is within the specified current rating. Also, check for any signs of overheating or thermal stress on the module.
Aimtec recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, and a voltage rating of 6.3V to 10V. The capacitor should be placed as close as possible to the module's input pins to reduce noise and ripple.
