Rob, .06mm to .1 mm is slicing the bologna pretty thin. Grab ahold of your placement shafts and physically pull back and fourth on them. There should no play. There are also sliders at station 1 and the placing station 11.(I think 11 is place) Make

Hi, We use 1:1 for 1 mm BGA and it works fine. We used it at 4 thou laser cut stencils when we had a manual stencil printer, but have moved to 5 thou with the DEK and it works ok. We originally went to 4 thou because of paste release, but the DEK

A suggestion for your stencil which works is as follows. Cut your stencil aperatures beyond your pads to a length of 0.1mm , this then allows the paste to pull back into the pad creating a blob of solder which can be inspected by AOI.Best length and

Hello Sr.Tech, There have been two types of nozzles made by Fuji for 0201's one was a 1mm tapered to .4mm and the other has a straight .4mm tube. Has one superceded the other and if you have used both types, did one work better than the other? Asking

What causes BGA voids over 25%? Have recommended profile for solder paste, hit 237C for 5 seconds and still get a void on 2% of specific BGA in various locations. BGA is FG676, 1mm pitch, on ImAg using lead free paste OM338 on a 6 layer FR4 PCB.

Hello, thanks for the help. Since this is only for prototypes we can avoid lead-free. Also our boards are not that big or thick. On the other side, our parts are small, the smallest is 1.5x1mm. Would the DRS24 work? What brand is usally more affor

Drill holes or tooling holes have higher tolerances than Fiducial marks during PCB fabrication. I would certainly recommend Fiducial recognition as a more reliable approach for better accuracy. You could re-calibrate the Vision system file used for

I have identified a Board design issue and having trouble convincing others of my findings. I have a BGA (Sn63 balls, +1500 IO, 0.6mm ball, 1mm pitch, with heat spreader plate)that has a high incidence of solder shorting on the corners. The board i
