I don't suggest using Pd/Ag or Ag/Pd terminated components unless you are forced to use them. You often see a line of demarcation that suggests a poorly wetted solder joint. I have had bad experiences with Pd/Ag terminated capacitors. Even when so

Hi Dave, The solder has tended to wet the component termination of Ag/Pd (chip capacitor) but has not wetted the pads, whereas the solder has wetted both termination & pads when using Ag/Ni/Sn finishes. Thks

I have question,is this the only Ag/Pd component in your board? If yes then concentrate on this component, I would suggest evaluating other component of the same value with Tin terminations. If I am not mistaken Ag/Pd plated components termination

Hi, We are using Sn/3.0Ag/0.5Cu solder paste on Pd/Ag pad metallization in one of our application. Could someone provide me information on the following: 1. How bad is the Leaching of Ag in SAC alloy and how it can be mitigated. 2. During reflow so

Hi, I am trying to assemble a LTCC component with Pd/Ag surface finish on to Sn/Pb/Ag solder and Sn/Ag/Cu solder. I am passing it through a reflow. I have observed poor wettability at the solder-pad joint. Does anyone have information regarding th

I facing dewetting problem on Ag/Pd termination(chip component)during reflow process. The solder wetting is pull to terminal side and exhibits dewetting. Any one ever face the same problem and any solutions for the problem?

Thanks Dave. But I do not understand why the solder being wicking away by the component itself. Does Ag/Pd finishes has stronger wettability than LF HASL finishes ? Rgds
