LPCC™ / QFN

Leadless Plastic Chip Carrier

LPCC The LPCC patented plastic package was developed by ASAT in 1998, introducing a "leadless" concept into ASAT's expanding portfolio. The LPCC package is a superior choice for high-speed applications where thermal and electrical performance is paramount and space constraints are unavoidable. For thermal solutions, this package has the ability to mount the die attach pad directly to the board for heat dissipation.

Features

Body sizes from 2 to 10 mm SQ*
Lead counts from 8 to 72
Standard assembly materials, equipment and processes
Ground plane bonding option
Conforms to JEDEC registered outlines for QFN (MO-220) and SON (MO-229)
Dual-in-line versions available
0.4 mm, 0.5 mm and 0.65 mm thickness options per JEDEC outline MO-248
Bumped LPCC available per JEDEC outline MO-250
Stacked die option available

Advantages

Lead-free and “green” options available
Lowest stress at solder joint compared to CSP & Flex packages
Saw singulation technique provides larger die pads for better thermal performance
Very low inductance for high-speed applications
Ten day design cycle time including lead frame
Immune to die shrink
Die pad mounting to motherboard provides for excellent thermal performance
