By What is difference between LQFP and TQFP?
TQFP (thin) and LQFP (low-profile) are common form factors for surface mount microcontrollers. The main differences between TQFP and LQFP is that TQFP has a maximum height of 1.6mm and LQFP has a maximum height of 1.2mm. The height does not affect the compatibility of the footprints, meaning they are interchangeable.
What does TQFP stand for?
thin quad flat pack
A thin quad flat pack (TQFP) provides the same benefits as the metric QFP, but is thinner. Regular QFP are 2.0 to 3.8 mm thick depending on size. TQFP packages range from 32 pins with a 0.8 mm lead pitch, in a package 5 mm by 5 mm by 1 mm thick, to 256 pins, 28 mm square, 1.4 mm thick and a lead pitch of 0.4 mm.
What is the difference between QFN and QFP?
The pins on a QFP IC are usually spaced by anywhere from 0.4mm to 1mm. The connections on QFN packages are tiny, exposed pads on the bottom corner edges of the IC. Sometimes they wrap around, and are exposed on both the side and bottom, other packages only expose the pad on the bottom of the chip.
What does Lqfp stand for?

What is a BGA package?
(Ball Grid Array) A popular surface mount chip package that uses a grid of solder balls as its connectors. Available in plastic and ceramic varieties, BGA is noted for its compact size, high lead count and low inductance, which allows lower voltages to be used. See surface mount, chip package, MicroBGA and flip chip.

What is lqfp64 package?
Low Profile Quad Flat Pack. Dummy Low Profile Quad Flat Pack (LQFP) packages provide the same benefit of the metric QFP packages, but are thinner (body thickness of 1.4mm) and have a standard lead-frame footprint (2.0mm lead footprint).
Is BGA a SMD?
What is a BGA? A Ball Grid Array Integrated Circuit is a surface mount device (SMD) component that possesses no leads. This SMD package employs an array of metal spheres that are made of solder called the solder balls for connections to the PCB (Printed Circuit Board).
