Thanks Russ. Everyone knows that when you clean your wave you wear a dust mask. Well that tells ya the lead is flying around. So same goes fr your oven. Hot solder paste turns into the lead. And like a wave it is very hot. Hot stuff vaporizes l

Yes, you can use lead-free parts in a leaded process. And the other is true as well, no-lead free parts in a leaded process. BUT, you should not use leaded parts through a non-lead wave solder process and of course, your board will not be RoSH.

Boy it is good to see the wave master back in action! I mean really guys, is Larry the only one here who knows that the lead turns into vapor in the oven and then in the cooling zones it falls back onto the board and creates the solder joints? P.

In passives I dont know if anything changed at all other than the terminal plating. As for Active components there has been much engineering done to allow for the extra heat needed to liquify say SAC305 or other lead free pastes without damage to th

Yes you can use no-lead parts in a leaded process. Your solder joints will be weaker than they once were unless you change your solder paste. You can try to improve this by running a hotter reflow temp, but be careful since your flux was not design

Phil is wrong. In the real world, we know that part mfgers have not changed every one of their parts to make them "high temp". They just changed the plating. Anyone who thinks otherwise, has never run a profile or touched a warm board coming out o

Let's talk pin holes and blow holes. I've been here since the transistion of leaded to lead-free process started for our company and we purchased a wave machine just to keep up with our lead-free orders. we put out 500-1000 boards a day both leaded a

Hi, Bill, Lead-free solder and paste manufacturers will be a great resource for you during the transition; they've tested their products extensively, and their application groups have been able to help me through the biggest changes. There are a fe

Jerry, In your initial post you give 260C as solder pot temp if you�re not using lead-free I would reduce the temp to 250C this will also reduce oxidation rate.

Agreed, I just bought a Electrovert Vectra Elite and have been very pleased with it thus far. I got the dual pot option for lead free changeovers and that has worked great. I can change pots in under 5 minutes, not counting the time to warm up.
