RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

What is a good Pb-Free solder to use? - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. If the folks at phpBB would release a version with integrated sign-in from the major social media platforms, I would resurrect the RF Cafe Forums, but until then it is probably not worth the effort. Regardless, there are still lots of great posts in the archive that ware worth looking at.

Below are the old forum threads, including responses to the original posts.

With the RoHS (Pb-Free) deadline quickly approaching in July, I still am wondering what is a good lead-free solder to use for general prototype and repair soldering? Some the the stuff I have used is really crappy. It does not flow well, especially without using a lot of flux. Reflowing is a real hemorrhoid.

Whay are you guys (and gals?) using?

I'm with you on this one James. Here is a link to an article on the Law of Unintended Consequences - very appropriate. I think that the whole thing is a boondoggle. Electronics lead constitutes maybe .1% of all lead in the world. Lead-acid batteris make up something like 40% of all lead waste. Let's get real here.
