Indy, We use Palladium silver surface finish parts for silver epoxy attached parts only. It is our understanding that this finish is not for solder, but only silver epoxy attach. I expect that is you problem. Dave

Hello Everyone, We are having some problem with Palladium-Silver surface finish. We have ceramic components with the above surface finish. When we try to assemble these on Sn/Pb solder, we are observing open joints. If we reflow the compt for more t

May I ask what component types you are using and who the suppliers are? FYI - If the components have exceeded their shelf life, they may have oxidized too much for soldering using low activity fluxes. Thanks and best regards, SR

Responding to your questions ... RELIABILITY OF 1% SILVER SOLDER PASTE: It�s as good as the next solder paste, all other things the same. Look at your back articles by Jennie Hang in SMT magazine. I want to say she wrote an article on the topic i

Sounds like your Si plalladium finish has oxide on it from the firing or sitting around too long. I used to assemble LTCC and have had plenty of dealings with this matter. The best and easiest is to get an active type flux and solder paste. AIM makes

If the terminations on your components are not barrier plated, you must be very careful about the amount of time you stay above liquidous. As you'd expect, longer is not better. The longer you stay at liquidous, the more of the component terminatio

hi All, i have recently running a Ceramic board with silver/palladium surface finish, using Alpha Metal 63/37 WS solder paste, soldering meet IPC standard after reflow, however, the solder joint look grainy, not sure if there could be too much interm

No suggestions, but we've also had problems with silver palladium. No wetting on reflow, when we tried handsoldering them, we could actually scrape off the whole finish and were left with a black unsolderable underground. It was just 1 reel, seems

No problem. If you get no joy you're going to have to change the footprint to a 1206 or 1210. Murata have a range of high Q value inductors (50-60) & from memory Toko used to be pretty hot too. The terminations on the coilcraft part are listed a
