Try TI's website. They have almost completely phased in the use of Paladium on all of their IC's. Their website has many useful technical papers on Paladium.

Tombstoning 0805s w/palladium/platinum/silver terminations We are experiencing tombstoning problems on 0805 packages that have paladium/platinum/silver terminations. It comes & goes...... I�ve checked the reflow profile, and paste deposition and a

Recently there was a thread on soldering paladium leads on ICs. A gent from TI suggested an article he had written. Various folks suggested making sure the reflow profile peaked above 215C. My question is: How does one recognize paladium leads so

I have been involved in SMT for only a few months so I am coming from a position of extreame ignorance. I have been asked to investigate the differences in soldering to components with Paladium coated leads vs the standard Tin_lead. I would appreci

Hi, We are using chip components with Silver Paladium coating and finding poor wetting. We are using the water wash solder paste with 2Ag and std. reflow profile. Any suggestion how to improve the solder wetting for those components. Thanks,

Gary, Paladium Leads have been a win-lose proposition as far as I can tell. The vendors win because they don't have to deal with lead and get higher yields. The users lose because of extra engineering time involved with incorporating this on their

This may be the nickle paladium lead material or an 87/13 tin lead plating on the leads. Paladium and 87/13 has a slower disolution rate and takes longer for solid joint to be created between two metal surfaces. Reflow temp must allow the joint to be

Steve - you must not work to IPC class 2 or 3 requirements. If the solder is "pillowed" around the lead, I would strongly suspect a wetting problem. Most of the Paladium leads I see soldered have a strong line of demarcation but no pillowing. Hav

Would the lead finish on this part happen to be Paladium? I had a problem similar to this some time ago and we found the lead finish was not tin/lead over copper but paladium over nickel. We had to increase the reflow to 225 deg. C peak temp with t
