Poor wetting to palladium

Electronics Forum | Mon Jan 29 12:42:24 EST 2001 | davef

Several points about your query are: * TI�s solderability protection specification is a minimum of 3 u" of palladium over 40-60 u" of nickel plate over a http://www.ti.com/sc/docs/products/logic/package/palladm/index.htm

Poor wetting to palladium

Electronics Forum | Mon Jan 29 06:44:59 EST 2001 | Scott B

I have recently come across a device which has a palladium over nickel finish which when soldered shows evidence of poor wetting to the lead ( i.e. a wetting angle greater than 90�) about three quarters of the way up the side of lead. This is only vi

ENEPIG or Imm Pd? Concerns about palladium as a solderability protection are: * Palladium is more difficult to process in fab than gold * Palladium solder alloys can be brittle, similar to gold, without proper soldering process and/or specification/

What is the disadvantage of palladium plating instead of gold plating? I saw many advantage of palladium plating in term of hardness, wear resistance, and price but why most of the PCB Industries still use gold in PCB pad? Thank you

I agree with Chrys, get the spike temp up and wetting is not a problem. However, when the palladium mixes in with the solder the joint will become more brittle. You need to make sure enough solder is printed on the board to minimize the concentrati

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

Solderability of fired-silver/platinum/palladium lead terminations

Electronics Forum | Mon Mar 30 08:11:22 EST 1998 | Derek Drabenstadt

Does anyone have any experience with fired-silver/platinum/palladium lead terminations soldering. I have had issues on nickel over gold plated boards but not with HASL'd boards with tin/lead pads. Is this the norm?

john, Immerson Silver is probably a good choice. What is your opinion abt Palladium silver. Does presence of Palladium affect the reliability of the pcb surface finish

Palladium silver surface finish

Electronics Forum | Thu Aug 12 20:32:44 EDT 2004 | usdigital

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
