They are very finiky. If you have good solder paste, and a slight down pressure, to make sure the LED is "stuck" to the board, you should be able to place it. Pick it up on the center of the flat, NOT the lens. Even with the vacuum turned off, t

Hi, it seems like you have some experience with the SM320... How do you feel about the reliability, and consistency of it? does it generate alot of error on a run? and what do you mean about feeders breaking the head? Also you're telling me that this

"The question is: should we be looking at the operator? the paste? or the setup?" Yes. ;) Those guys love to brag about their 4 corner height adjustment on those printers. The fact is it's a PITA and shouldn't be necessary in the first place. It's

Hi, I have a FUJI CP4-3 machine that is experiencing issues with missing components. The machine keeps on running even after many parts are missing and it releases the board thinking it's complete. For an example, say there is 200 components to pla

Placement force usually refers to the amount of force an SMT nozzle applies to a part when placing it. You want enough force to push the component onto the paste but not so much that you damage the part. Some specialized applications involve placing

From what you described of what you seeing from the slow motion is that the part is not actually "placed"; it's more like drops on top of the paste, so it's floating on top only which vibrations would cause it to slips away. Even though I am not fa

We have also placed BGAs with IP-2, with no problems. Ours were 50 mil pitch PBGAs, and as Doug says the perimeter is more than enough to place the part. We have only placed from matrix tray so far. The ONLY problem is the center array, for parts tha

The heat from a soldering iron will push raw flux across the surface of the board and into surprising places. It's bad practice to squirt liquid low residue flux on the board during rework, because the portion of the flux that does not get heated pr
