Had good success with Meg Array and Micropax SMT and through hole. The
Micropax through hole was a little nightmare to rework at first. The Meg
Array was a comparative breeze.

SMT placement with any Meg Array version (low to high ball count and number
or rows/columns) works well because of the little cap that is used to
interface with the vacuum nozzle for placement and rework. The connector
"forks or fingers," used to mate are a bit tricky but work well. The plastic
body (what's the material) has good thermal properties so CTE presents no
problem.

The Micropax SMT connector series uses no balls for solder attachment. It's
only big problem is the lack of a good alignment/board insertion pin so
placement is a little difficult. Might be fixed by now.

Don't forget a good rework plan as you don't want to go assemblin' without
it.
