Dave, That's exactly what we are seeing. There is a trail of components leading away from the pick point, all of which are 0402 parts. I can remove the feeder from the machine, advance a few parts into view, turn over the feeder and only half will

hi kris well 0.02 cents south african money is a lot less. but anyway we have a customer with 3 lines all lines are the same equipment and we have had major problems with 0402s .on some manf reels .as a test we moved one reel around and the problem m

Has anyone experienced profile related microbridging under 0402 capacitors in the past. We use a Sn46Pb46Bi8 paste, 178 degree C L.T.. Double sided board, 2 per panel, 6.5" x 5", convection oven. Profile data; thermalcouples @ components showing 200

Hopefully it is just the part data a little bit off. But if that doesn't help, make sure the thickness sensor is calibrated bang on. And do the nozzle height adjustment. What are your nozzles and filters like, as far as being clean goes? I've put dow

There have been many designs of apertures for 0402, round, home plate, inverted home plate and various reduction amounts for square or rectangular apertures. What works best for a given application depends on PCB design, solder land finish, stencil t

Well I finally got the power turned back on at my house. Guess they only let ya slide so long without paying the bill. I still say 4 months is OK - especially inthe winter time. But requardless, wave soldering 0402s is nuts. Getting adhsive to fi

Sounds like you've done a good job of troubleshooting. Two thoughts are: 1 An alternative to using a hotter flux that the others mentioned is to use components with more solderable terminations. [A firm grasp on the obvious.] 2 You spoke about

I figure if you need the rest, you don't need these. These strips are from some laser cutting tool fabricator. They give them to their customers [laser cut stencil fabricators] so the customer can do a good job. Yall have a nice day now, y'hear?

Have you checked the placement height? it will need to be set down to about 0.5mm - 0.6mm, whereas you can get away with 0.9mm for 0603. Not a Panasonic expert but I've seen this nearly every time a customer has taken the step down. Cheers, Rob.

In the PD for 0603 I have a min size of 0.7mm and a max size of 1.0mm and the CP4 size at 0.0mm. This way when you have 1.0mm nozzles in the machine it will use that and when you change them to 0.7mm it will use that. Both sizes work OK. -Jerry
