Git otta taun!!! I never have heard of an Sn62 BGA solder ball. Several thoughts on Sn62: * Look at http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=4603&#Message17953& * Search the fine SMTnet Archives on � Sn62 �

Sn62 eliminates voids on BGA ?

Electronics Forum | Thu Jan 15 09:04:36 EST 2004 | rkevin

Does anyone have any information about eliminating voids on BGA using SN62 as opposed to the normal Sn63, something which explains the inter-metallic layers which form during the soldering process and the leaching out of silver ?

Jim, Yes this does keep on coming up in the forum as JAX states. There is a pluther of information in the archives. I have had some problems with 0603's in the past. If it is possible, try using a 2% silver SN62 solder paste. This helped me in many s

I have had similar problems and my customers have had this too. A two story drop test was made by one of my customers and they found that changing Sn63 solder to Sn62 solder made a significant impact. There is no real downside other than a slightly

I have found that Sn62 solder gives better strength and leach resistance when soldering to gold surfaces. The gold needs to be at least 5 to 10 micro inches thick to prevent nickel oxidation but if over 25 micro inches will cause brittleness. I hav

How are you guys checking parts for RoHS compliance?

Electronics Forum | Tue Dec 13 21:25:33 EST 2005 | Slaine

the part is a pi filter device, originally the supplier was nanufacturing it with HMP by dipping it, the giving it a Sn62 over dip to maintain solderability, to supply a RoHS compliant product they just left off the Sn62. so yes on compliant part the

1.) Are there any industry white papers written that document any advantages in running this alloy? From what I've read, this alloy was formulated to prevent leaching of silver for silver-bearing component terminations. 2.) Are there any concerns w

| | We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have t
