Ideal situation is get a technical rep from the solder paste supplier. They know their paste better, and should be able to work out a profile based on their paste and your oven. Again, a technical rep, not the sales guy.

Do you have a Slim-Kic? You can run a profile and then do predictions from there. Very useful tool.

Some profiles can be difficult to get exactly, so I was wondering what effect a slight deviation might have.

Have you tried the alcohol based flux on your ive yet? (even if it isn't specd for leadfree). Water based flux seems more prone to solderballing. edit: why is sel ective changed to ive and alte rnative changed to native?? censorship for innovation

I would have to second the opinion on the water based flux. If you don't want to deal with the solder balls, switch to an alcohol based flux. Unless you have a board that takes a while (water based tends to stay active longer), alcohol is easier to

GR@ICS, I copied and pasted all of the thread here including the photos and sent them to our programmer for the machine. I will get back to you if he doesnt come on here himself and respond to your problem. Hopefully we will have an answer for you

Too much flux will spatter and can leave balls on either side. From your pix you may too little flux. Try turning up and see. Also try hand applying your alcohol based flux and running through. Will take away a few question marks.

I would like to thank everyone for their help on this one...We havent had the board back at S E L E C TIVE on this yet, But I will keep all updated (if there is the care for it... Thanks again

One oven can run both, but your profiles may vary. You will not contaminate your lead-free by running it behind the leaded stuff. Even if you spell "native" as "native".

We are having solder issues with this part. (See attached picture). Placement is good prior to reflow. All other parts are reflowing well and oven profile matches paste mfg. specs. well. This is non-ROHS, WS process. Any ideas on what might be h
