Introduction to LLP® (Leadless Leadframe Package)


Small Footprint. Cool Thermal Performance. Low Profile.

LLP Chip Scale Packaging.

National's New Thermally Enhanced Package Offers Optimum Performance In A Minumum Of Space

LLP Chip Scale Package

 

Reliability

  • High PCB density 0.8 mm max. package height
  • 8-Pin dual-in-line to 44-Pin quad configuration
  • 0.5 mm - 0.8 mm lead pitch (depending on lead count)
  • Inherent coplanarity
  • Soldering exposed die attach pad to PCB offers optimal thermal performance, enhances package self-alignment to PCB during reflow.
  • Uses standard SMT placement and reflow equipment
  • Negligible package lead inductance for faster signal response, less cross talk, and ground bounce

 

 
  • Passes all standard product reliability tests:
    • OPL, THBT, Temp cycle, Autoclave, and ESD
  • Passes all standard board level reliability tests:
    • Drop, Vibration, and 3-point bend
  • Meets JEDEC moisture sensitivity level 1
