HLMP-4015 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Broadcom recommends a PCB layout with a solid ground plane and thermal vias under the package to improve heat dissipation. A minimum of 2oz copper thickness is recommended for the PCB.
• How do I ensure reliable operation at high temperatures?
  To ensure reliable operation at high temperatures, it is essential to follow the recommended operating conditions, including derating the current and voltage according to the temperature derating curve provided in the datasheet.
• What is the recommended soldering profile for the HLMP-4015?
  Broadcom recommends a soldering profile with a peak temperature of 260°C (500°F) and a dwell time of 10-30 seconds. The soldering process should be done in a nitrogen atmosphere to prevent oxidation.
• Can I use the HLMP-4015 in a humid environment?
  The HLMP-4015 is not hermetically sealed, so it is not recommended for use in humid environments. If operation in a humid environment is necessary, additional protection measures such as conformal coating or potting may be required.
• What is the typical junction-to-case thermal resistance (RθJC) of the HLMP-4015?
  The typical junction-to-case thermal resistance (RθJC) of the HLMP-4015 is around 1.5°C/W. However, this value can vary depending on the specific application and PCB layout.
