Hi Gee I got computer crashed at my last try. I am glad to see my note got through pointing you to the other contributors. One thought about that profile they give is that they JEITA or Jedec or ??? with a J is striving to balance what they know

If you can change to SN100C do it. The nickel prevents the high tin content from eating away at the metals on the tips. Similar to what the Lead did in 63/37 alloys. This Koki crap is just that, crap. 99% tin??? Thats what is causing the problem peop

A place called Lace Technologies is in St. Charles Ill. They specialize in running lead free protos etc. Could save you some money in the long run. Charlie Han is the guy and http://www.leadfreeassembly.com is the web site. Or call Charlie Han 1-

if you have enough free space at the edge of the board you could try some titanium supports, I have to use these on some products to prevent warping. Also, in relation to profile and I know there are a lot of variables to consider but is 225 not a b

Not being funny here but I understand exactly what you are saying and sounds exactly the same as we experienced. Seriously try a different paste. Give Tamura a ring and I am sure they will give you a sample. I don't have the exact part code but they

I can't answer for wave, but we tried some Sn100 paste for reflow, and couldn't get it to work worth a darn. I then got some SAC305, and was relieved to see it work almost as well as SnPb at its best! Much better wetting and flowing to the various

Wow, 90%? I've only been doing this 20 some years and never noticed! So buying an inspection machine gets rid of my defects? I should have bought one long ago! I don't think so. I won't even go into the lead free area.....

We are not having any real issues. I am just first setting up a lead free profile, and was looking for a starting place. So far it's going well. Can you tell me more about why your paste would be better and I'll pass that on to the decision makers?

Sarry, Word on the street is that your profile will have to be hotter, maybe up to 20C hotter, I have trialled lead free. The sales guy said, "Right, lets reprofile your oven ! I said, "No, lets try it as it is.....! The results were fine, as the

I assume you mean Dr. Jenny Hwang--I attended her lead free seminar and found that most of her info is a good place to start. One of the debates about her work is whether bismuth should be used in any formulation. Many of the paste manufacturers di
