That's why you have to read between the lines of any article. Even with data from a paste manufacturer, it's still a bit fuzzy on how their paste will actually work. Not many companies have their data that solid, so it's better to experiment and me

Anybody out there using this with lead free paste and willing to share the good and bad? I used them a few years back and had some issues (wasted paste, paste bleeding out around the skids). Just curious if DEK has addressed those problems and how cu

pr, I don't believe there is a differance in performance of the ProFlow head between "Leaded" and "Lead-Free" paste. We have been using the ProFlow for about 4 years now with leaded paste. Yes, some issues to overcome. Mostly in the brand/type of

Smaller Ovens reduce your ability to create extended soak times. Extended Soak Time requirements are determined by your thermal variant across the product. A 5 zone oven could work if your boards are not extremely complex but you are the only person

Kevin, I'm using a 1700W with no problems so far. I have recently completed trials on nine different paste brands on a 1500 as well. Remember the tunnel length is no different between a 1500 and a 1700.... Let me know what paste you are using and I m

We have profiled hundreds of ovens here and it really is dependent on work going through, I walked in on one trial and was faced with an oven that was literally two foot long and told the guy it would not be suited only to profile and run lead free t

Fellas: I'm having a tough time with voiding with my lead free water soluble paste under my large BGAs. I know some is almost inevitable, but this is more than I'd like. This is with a slope of .9, soak of 60 seconds, above 217 for 85 seco

I agree with Rob that voids are often times paste-dependent, and it's all about the type of flux that's used. The cause of the voids, as you all know, is outgassing of flux which has nowhere to go with BGA's. Some paste mfgrs. will recommend going

The challenge regarding the stencil was mostly due to the actual board layout and nothing having to do with the voids in the solder. It was my first encounter with 0.5 mm pitch on BGA and dealing with a LF solder paste with higher viscosity than tha

Bill, Likely the latex isn't conductive, so charges will not be dissipated to the metal rack. Whether that constitutes an ESD risk or not will depend on the generative properties of the latex. I've never tested units inside my wash, so I can't spe
