Bill: I'd expect better gasketing on a nice flat solder mask surface rather than the edge of the stencil opening mashed down on a irregular shaped hunk of solder attached to a pad. Stop thinking and get printing Dave F

Be careful if you use Ni/Au. The "black pad" phenomenum can be crippling. We moved from Ni/Au to OSP because of it. I also don't want to return to the lack of flatness of HASL.

Some PCB's manufacturers are now able to fill the hole and then re-metallized the pattern in order to obtain a final soldering surface perfectly flat but with an electrical connection under. This of course increase the price of the pcb but avoid any

Hi, how to ensure flexible boards do not warp after reflow and still remain flat for subsequent operations. What is the best way to hold and transport these strips from one process to another. Thanks!

Firstly, Verify your Z-height per the procedure in the Maintenance manual. In general, release the placement stopper and rotate cam onto flat surface of board with z-axis at zero. There should be 0.15 mm compression of the spring

Has anyone out there tried placing BGA's with a Fuji IP2? Fuji says flat out no way but I think we can if we get them in T&R.

Has anyone used Fuji's rubber tip nozzles for the IP3? Are they O-ring type or suction cup? I'm having trouble picking up Ompacs due to the top of the part not consistently being flat. Any actual experience with these $1100 nozzles would be appreci
