Are you using lead free paste also? Are all the other parts on side 1 ROHOS ? etc.. can they handle your leadfree profile. Those need answered 1st. But to answer your question. Yes you can run the BGA side 1st ( hopefully with leadfree paste and ho

Hi All, We did not change our internal Solder pot components (stainless steel)when we switched to Leadfree Alpha SACX . Running approx: 1 year now and I carried out checks yesterday and we have some signs of erosion. Did not expect to see this so s

It's possible that your lead-free solder will stick to mounting bolts more than SnPb solder. Lead-free solder has a high tin content. Tin is a very good solvent. You may need to coat the bolts with a solder mask to prevent the solder from sticking.

Good afternoon, Google search engine (http://www.google.com) might be very useful for you :) Much has been written on the net about the topic you are asking. So the search keys will be �X-Ray� and �Voids�. For instance: http://www.aciusa.org/leadfre

Ed: We agree with you that leadfree parts can be used with leaded paste. We disagree that lead part can be used with leadfree paste. Here is link to a previous discussion here on SMTnet on the topic: http://www.smtnet.com/forums/Index.cfm?CFApp=1&M

Test results indicated that the life of lead-free solder at a 2512 chip resistor could be worse than of SnPb solder in the accelerated thermal cycling condition. [Development of Life Prediction Model for Lead-free Solder at Chip Resistor, Changwoon H

Hi Tony, You should search the archives as there is a lot of threads on this topic. A couple of quick checks - 1 - Are you running a Leadfree Process ( if you are not Leadfree maybe the BGA is ? ) 2 - Check your reflow profile is hitting all the

We've done some tests on this and got good results. Of course it can be dependant on the paste properties (thinking of slump in particular), and you need to get the heat under the connector which can be more critcal than in a leaded evironement, but

Are there profilers that I can use over my leaded and lead-free wave that can also profile my reflow ovens (leaded and lead-free). I'm not that familiar with either but as I learn I can't help but think that there should be something on the market t

I was asked to try and find us some good Lead-Free soldering Irons, I know all Irons are "LEAD FREE" I mean I need to know if anyone has any recomendations for an Iron with really good recovery time, that is higher heat capable. For a price that isn'
