There's a lot of comparison tables on the web. Here's one: Properties - Summary [A Winlow Circatex] Attribute||Hasl||Immersion Silver||Immersion Tin||Electroless Pd||OSP||Eless Ni / Imm Au Shelf Life (months)||12||12||12||12||12||6 Multiple Reflows

The biggest difference between the two, is solder joint appearance. What I noticed mainly is that the solder does not wet and flow as readily to a palladium coated lead as it does with a tin/lead coated lead. When you look at a palladium coated lead

Scott, I am a little confused, when you mention "silver thru hole vs. plated through hole what do you mean. A silver "immersion" type finish vs. HASL (Tin lead)on your PCB? Or are you talking about using silver solder to perform intrusive reflow of

Just a comment to clarify this discussion. Typically chip caps and other passive components that use palladium plated to the end of the component are very different from the TI nickel/palladium plated IC components (leaded devices). The main di

Has any one experienced hand soldering through hole components to white tin plated PCB's using no-clean wire solder? Our facility is presently evaluating white tin vs Sn/Pb coatings. Our only difficulty at this time has been hand soldering of wires

Gary, I'm pretty much the main contact at TI for palladium lead finish questions. We have a web site at "http://www.ti.com/sc/docs/asl/palladm/index.htm" which has technical papers I have written on the subject. Also, you'll find the Pd Lead Finish

Our customers use OSP, HASL, immersion tin and immersion gold as board finishes. If I recommend a finish to the customer, it is one of the immersion finishes or OSP. Those finishes have the advantage of a flat surface to deposit paste. HASL has va
