Hi Bob, Do you have information about IPC D-35 for reference? What moisture sensitive level is the Sn-Pb/RoHS of PWB? Does PWB supplier start to implement PWB drying packaging?

Every problem faced with (all) lead free alloys can be solved with 2 words �add lead� I'll keep it short don't want to sound like a broken record.

looks like my knowldge preceeds me again. I woud try a different flux. If it doesn't work - it will take a question mark away and your one step closer to total success.

you need to check your angle on this, can you measure and advise what you have cheers Greg York

The angle is a standard Soltec 7deg. We don't have the tools to measure this accuratly, but I do trust Soltec on this.

Great as most Lead Free machines have the wrong angle on them 7 degrees is correct. So you are still exiting the wave in the middle of the pot then.

Our UIC Lightning Head is having pick issues with Vishay reels (0402,0603) when the reel are near the end. It occurs ~300-200 pieces before the end of the reel. Pick point was confirmed and is consistent. Has anyone experienced this issue nearing the

We have an ac30l advantis machine with a lighting head for about a year now we place a lot of 0603 parts some from vishay we are not seeing this problem yet

Its mainly on the heavy hitters when the head is sitting over the feeder (Gold) and doing some multiple picks. Again this only seems to happen near the end of a reel. If we splice the reel is it picks perfectly directly after the splice.

I had similar problems with some Chinese 0805 capacitors. Some parts simply won't get out of the paper tape - like they sticked to the bottom paper tape... It happened on two reels, the rest was OK, so I suppose that was some "glitch" on their side..
