Hello Brad, We are running the Slim Kic 2000. We have found the predictions to be fairly accurate as long as the suggested change is within 20 degrees of the original recipie. As a test I ran a board with the wrong profile. The predictions got me wi

Wow, I'd have to say the exact opposite. Compared to MPM the DEKs were WAY longer to program. But find out for yourself CN. Program each and get back to us. Don't forget to program in 2D as well. That will be the kicker! As for spending money,

Had exactly the same problem the other week. Baked some boards did improve slightly but not convincingly. Washed bare PCb and found excessive HASL fluids left on board from improper rinsing and problem disapeared. Baking HASL fluid out is impossible

I'm probably not telling you anything you don't already know, but a technique that's worked very well in the past for me is to methodically step through every part of the process and observe your boards being built, or take a scrap or simulated one a

I'm in the high reliability (exempt) sector and have thermal cycled hundreds of boards in the past few years. As far as which is more reliable, SnPb or SAC305, my data is similar to what the technical literature is saying, "It Depends". In low stra

No, we haven't compared bills because we rarely let it cool completely down over night. I would think that the cost needed maintaining 200C over night versus 310C over night would be about the same, but a little less. But going from 25C up to 3

Zinc from the brass diffuses into the solder and reacts with tin causing dezincification. Dezincification is a specific type of de-alloying, or selective, leaching corrosion of brass fittings. This type of corrosion selectively removes zinc from th

The letter below was dated December 13, 2006 from Kester's Senior Market Development Engineer. I guess since then they have moved production back to Mexico. We no longer use EM907 as our primary Pb-free paste so I haven't seen any containers in a w

Hello All, I read AIMs article "Time Above Liquidus". It was very informative and a good read. One thing that the article didn't touch on, that is a mystery to me, is thermal shock to components during the ramp up stage of a profile. If you
