Jacky, we have had a similar problem. We needed to go to a smaller nozzle and also check your vacuume system and air kiss.Could be after placement when the machine blows air to insure the part is off the nozzle that it is effecting the solder brick.

You need to get yourself a copy of IPC 610. this has all the specs regrding placement and registration. chip aprts are allowed to have 50% side overhang. the fillet requirements are "evidence of wetted fillet" . I would not know if a cap being 51

Thanks all for Your input. The thing is that we want to avoid to go in to the pattern program and change the height in the middle of running a board. For ex. We start a product, feeders are loaded in advance in the feeder preparation area, operator

Hi all, At our Fuji CP-6 machines we place a lot of 0402:s, 0603:s and 0805:s chip capacitors. Our problem is that the height of the components can sometime be very extreme from different vendors. I am sure you all have experience of this phenomenon

Vision Type 12 may work also. You may want to try vision type 20 with backlight calling out the leads. Or you could use a black nozzle and try VT:180.

Ahh yes, 254. Don't give up on the other vision types. 254 can give you skewing as well. Your width and height are awfull close. Even with the 0.5 tolerance it is using the tolerance and saying that it is OKAY. Maybe what you measure is 1.8mm for wit

hello Everybody I would like to ask you for advise. I'm fighting with correct placing one of capacitors in TNT-A package at CP-6 machine. Size of this component is: L=3,4 mm W=1,7 H=1,7 Its Tantalium with J-lead. I use for this component vision type

This type of component packages works best with vision type: 254 - irregular. Measure the total package length including the leads. Also set the body dimension x-y tolerances to at least 0.35mm and the the pick up x-y tolerences to 0.5mm in the part
