FEATURES

Underfilms
Assembly and Reliability of Preform Underfilmed BGAs in Drop Test and Thermal Cycling
Pb-free solders generally are inferior to Pb-free solders in drop or shock testing. Preform underfilms can provide greater BGA to PCB mechanical robustness in a fairly seamless way – attached on reels similar to passives and reflowed simultaneously with the components, with only a minor design change required. And the results are impressive.

Apex Expo Recap
'Trekking On'
Following three tepid years in Las Vegas, a move to San Diego offered the annual trade show a new lease on life. And like the last time it was held in this Southern California city, Apex did not disappoint. Plus: Our annual SEA and NPI Award winners.

EMS Top 50
Hard Lessons Learned
Mother Nature put the hurt on contract assemblers from Japan to Thailand last year, but it wasn't just gravity that brought the once high-flying Elcoteq back to earth. It was almost enough for us to overlook another year of controversy at Foxconn. (Almost.) Elcoteq notwithstanding, the 10 largest EMS companies remained mostly static in 2011. But there was plenty of movement below.
