Electronic – Difference between BGA and LGA

pcb

I have come across a chip which is only available in LGA. I wouldn't touch BGA, but what about LGA? How possible is it to design for one with little experience? Are there any gotchas? I'm planning to reflow solder these using a hot plate.

LGA is similar to BGA, but without the solder balls, so you have to apply solder paste to the pads with a stencil. I don't think you will find them any easier to use than BGA.
