Performance
BQFN
LGA
• Better Thermal Efficiency in 40%
Smaller Package
– 13°C/W (BQFN) vs 15.2°C/W (LGA)
– Yields up to 50% longer life
• Access to Signal Pins
– Pins on Outside
– Easy to route Signals, Vias, Power
– Easy to inspect solder joints
BGA
• High Temp Reflow
– BQFN capability for 260°C
– LGA / BGA <250°C otherwise internal solder can melt
and spread thru delaminated areas
