digiman, the phillips fcms give us about 70k+ placements per hour. one of their reps lives on site. it is nearly twice as fast as our panasonics. both place the parts - which after working with fuji is not something i take for granted ;-)

the problem i have with the mpas - new and old - is that they have one table size. we build primarily smaller boards. one mpa is my gate where all the components are vision. therefore, the length of this very big table must be traversed to the camera and back to the board. this is a joke. it is also my gate machine by about 30%.

i've worked with fuji gsps (what a joke w/ no downstop feedback - you'd go through a stencil every two weeks), cp 4s and 6s, and ip 2s and 3s.

i've also used panasonic mshs and mv 2s as well as several versions of the mpas.

in the case of phillips, i've used the old and newer version of the fcms, the topaz machine (much more productive than the mpas). there is also another machine but i can't think of the name now. it is similar to the topaz.

phillips is great for long, very long production runs. changeovers are a bear. remember, we typically run smaller circuit boards. the phillips machines may not be as useful for larger pcb assembly.

i also like the automatic mpm screen printers. the only issue i have is that the phillips machines are so fast the mpms have a hard time keeping up.
