All, I'd like to know what a good used wave pb-free solder machine out there? Appreciates!

"Solder alloy compositions are numerous but the most important are still the tin lead solders which were used by the Romans. Tin melts at around 232�C and lead at about 327�C in the combination 62Sn 38Pb the resulting alloy melts at 183�C. This compo

I currently have issues with "slivers" of solder on or behind QFP devices. This has only occured on PB Free boards (we currently produce PB and PB Free on same equipment). This is not tin slivers, this is a long thin sliver of solder measuring up to

Are you talking about Durastone? That's what we use for our wave pallets. Both our wave vendor and solder bar vendor told us that we had nothing to worry about as far as Pb-contamination of the pallets. We have used the same pallets across our Sn

Indy, I found the same findings as you. The claim is that the solder joint may actually look closer to a SnPb solder joint then the SAC alloys. I had commited to the SAC alloys at SMT before finding out about the SN100C alloy. I'm interested in what

Ther is a solder alloy out there that is supposed to allow lead free wave processing without having to upgrade pumps and such or increasing the pot temp (direct drop in). I have not used it nor do I plan on doing leadfree wave soldering but you may

Hi, What would be the standard band width for Pb-free soldering? As per my knowledge this should be 3cm to 6cm. What is best?

Band width relates to conveyor speed to achive a 2 second contact time for Sn/Pb wave soldering. A typical conveyor speed is 150cm/min with a band width (contact band width between PCB and solder) of 5cm. Now for Pb-Free wave soldering a longer conta

Just change the flux. I have had bad experience with IF2005

Hi all ! I have a very simple ( maybe stupid ) question : Can we mix the lead-free components with 'Pb components' ? I mean, some component would lead-free, but it is only 5% of the whole. Will I have problems on wave and on reflow ? Thanks for hel
