From what I have read so far the temps are, if not close to being the same for both alloy formulas. Preheat is a function of flux activation and thermal shock. Solder temp varies from place to place. Russ

I have seen the solder shoot out at least 4"-6" from both the leading and trailing edge when this happens. If the open pockets are real deep you may want to use a turbulent/chip wave for soldering, sometimes this leaves bridges however.

Make sure that you are running the right leadfree profile. You may want to verify that it is correct with thermocouples. Use Indiums Tacflux023, This should work. As far as cleaning them after this I will have to leave up to you. Russ

My experience showed that stage 4 (which I assume would include a complete BOM conversion) is the most time consuming and challenging task.

Thanks Jay, Concerning your FR4 material, do you keep the same TG than what you use with Sn/Pb? Response from everybody would be also appreciate. Thanks and regards, Frank R.

I agree with you. And if you want a backup vendor in case of BO, I don't think it's possible to get it from an other company.

Jay ~ do you have any other contact information for that seminar you are attending concerning the SN100C? I have tried the URL in your message, and it is not working for me. Your help would be much appreciated, and thanks for sharing all your helpf

I have the same Heller 1500 and am about to start evaluating paste. Would you be so kind as to provide your oven set points to give me a baseline to start with? I think this would save myself and others a lot of time and effort ;-) Thanks James S

MarcA: Could you expand on the results you observed about improved wetting in a nitrogen environment? I am very interested to learn about the impact that nitrogen had. Was there an improvement in the cooling zone with nitrogen? Patrick

We are looking for a used or new wave machine must be able to do lead free solder. Does anyone have contact information in the Chicago, il area for used wave soldering machines? Thanks for any help we can get.
