Hi, Yes, I would be interested to know what the nature of the high failure rate is with using lead free BGA parts with a lead process. I had been to a seminar where they said it was ok, but not ok to use a lead BGA in a lead free process. Regards,

Today is more complicate to find components with lead than with "lead free", and the, I think that you have very feww lead components. And, if don�t work on exceptionals companies, you MUST use LEAD FREE PASTE. In one case, or in the opposite, the re

Larry, SMTnet.com did an Onboard Forum regarding lead free solder. The link : http://www.smtnet.com/onboard/get_forum.cfm?session_id=4& Also, I did a search of the SMTnet forum (left side of most pages-please be patient it takes a moment) using th

Can you recomend any information sources regarding European and Japanese Lead Free Solder Regulations? Are these pending regulations (WEEE) something that the entire EEC is looking at? As a company that exports to Europe what adjustments can we expec

Most Lead Free Solder suppliers are saying that stencil aperatures should go to 1:1 or have no change from previous stencils design. Only one solder supplier seems to be complicating the process....is their solder very different?? Can anyone share st

Dear all, Recently our lead-free samples being rejected due to very dull and sometimes grainy and very porous surface on solder joints. This samples was flow thru' the lead-free wave soldering with SN100C alloy composition. Referring IPC-A-610 D, le

Are you using lead or lead-free solder? 260C would be good for lead solder but may be a bit low for lead-free. We run our lead-free selective solder pot at 300C although we do not have any pre-heat or top heat, just hot nitrogen blowing around the

First thing try a different solder paste. All solder pastes are not created equal. Also if everything else on the board looks good then check the part. As far as nitrogen goes its about 4 bucket loads you need an external tank. I have seen some marg

Another basic soldering question. I notice that lead-free solders have become required for plumbing applications due to legislation. In a local hardware store, I noticed the existence of lead-free solders (based upon tin-copper I think) with a melt

Hi All We have run SMT process with SnPb but we’re installing some lead free components like capacitors and resistor lead free. After the reflow oven all components have good appearance with solder join sheen. But the lead free components the solde
