TLA™

Thermal Leadless Array

LPCCASAT's evolutionary leadless package, the TLA™, is the next generation in leadframe packaging. TLA achieves up to 75% reduction in board area as well as dramatically reducing total signal and wire lengths. At a lower cost per I/O than traditional wire bonded packages, the TLA has the highest I/O count per body size in a lead frame based package. The TLA is able to replace QFPs, single and dual row QFNs, QFPs, and FPBGAs.

Features

  • Body sizes from 2 to 15 mm SQ
  • Lead counts from 12 to 396
  • 0.4, 0.5 and 0.65 mm pitch available
  • One, two, and three row options
  • Standard assembly materials, equipment and processes
  • Stacked die, MCM, SiP options available

Advantages

  • Extensive design flexibility (isolated power or ground rings, segmented ring, multiple DAP, terminals where needed)
  • Allows fixed body size JEDEC compliant standards or an optimized custom body size based on the die size
  • Cost-effective leadframe-based leadless package
  • Quick turn lead frame design, no hard tooling required
  • Excellent manufacturability with rigid carrier
  • Strip test ready (no partial saw required)
  • High performance with excellent heat dissipation with DAP soldered to board and low inductance due to short electrical paths
