2.4 Assembly Guidelines

Please follow the recommended assembly guidelines for the LMG2100R026 samples:

  • Use low temperature solder paste (like Sn42-Bi58) whose melting temperature is around 130℃-140℃.
  • Soldering using bottom side heating:
    • Recommended for thinner board (less than or equal to four layers) with no components directly underneath the device.
    • Place the solder paste as per the stencil recommendation given in the data sheet.
    • Board held on a pedestal at around 2-3 cm from the top of the hot air blower and device is aligned to keep on the footprint.
  • Soldering using top side heating:
    • This method is recommended for thicker board (more than 4 layers).
    • Use hot air gun (with temperature set to 400℃) and blow the air around the device avoiding directly above the device (temperature can be higher but used for shorter duration).
  • Look for proper soldering connection of signal pins. If there are excess solder, then please remove them manually using solder iron.
  • Avoid putting excess solder paste especially near the edge of PGND pad (pin number 6).
  • If the assembly is done through automatic re flow oven, then set the temperature to less than 180℃.
