Hi,

I see the two package format are similar. What is the advantage of MLF
and TQFP? Which one is cheaper?

Thanks!

If I remember correctly, TQFP is 25mils spacing and MLF is 0.5mm.

MLF is certainly cheaper for the chip and PCB.

But:

1. Most of the chips I am dealing with are still in mils, unfortunately.
   Having mixed systems is just a headache for me.

2. Assembly costs are ridulous for MLF, especially for small volume.
