I agree that something has to be done with the lead waste but I believe that a recycling program is a better alternative to lead-free. Isn't silver more toxic? How about the venting of alternate alloy fumes, let alone the effects on operators. I say

Greetings from Mexico I can see several good opinions about the "real" need to chnage to Lead-Free processes, but at the end and trying to be real, is there any good path we could follow to stop this process? I can see a lot of work, investment in eq

Tough to say. Can you accept the loss of strength of your solder connection if upto 2% of the solder is affected? * Lead and bismuth alloys can form a eutectic composition of Bi52Pb32Sn16 in the grain boundaries. * Melting point of the eutectic all

Hi, I don't know if I'm being naive, but I'm seeing a number of 3 zone (+1 cooling) ovens on the market that claim to be for Lead Free soldering. Trying to follow component & solder manufacturers ideal profile can be tricky with 7 zones at times so

You never mentioned the size of the board? You will find a vast array of pre-heaters with a range of prices. I could reccoment a few products based on the size of the board in question. The solder iron staying at temperature while not being used is a

If you have some tool which can be convenient for repairing component mounted with lead free process, please email to me, I am interested in them very much. In my opinion, to repair a SMD component is not difficult. The most important thing is how

Cheers Jerry, forgot the most important one! Also want it to do: laser 3D volumetric solderpaste inspection Pre-reflow (including fault logging by placement machine & individual feeder) Post reflow solder joint inspection & handle lead free joints

Eric: For the amount of dross that you're removing, we're concerned that you could be loosing the balance of your solder alloy, because dross consists primarily of tin oxides. It has little lead in it, beyond than the lead content of the solder that

Most component fabricators don't properly understand the impact of soldering with pure tin solderability protection on components. Here's one that does: "The Effects of Board Attachment Processing on Sn Whisker Formation on Electroplated Matte-Sn on

Joseph, We have all been using lead free components for some time. Many passive already have a Pb free plating and we have not seen catastophic failures on them. From the information I have seen, I think this should be OK (with the exception of BGA'
