We are using 1mm BGAs quite frequently now.
The rest are fairly standard

                Subject:        [DC] SMT packaging trends

                I have to prepare a report to our companies Board of Directors that explains
                where SMT packaging trends are headed.  Please help by letting me know which
                types of IC packages are becoming more commonly used.  Also (and here's a
                specific question!), what is the most common and the smallest pin-pitch for
                QFP's, BGA's, and micro-BGA's.

                Thanks to all in advance for your input.
