Rohs and non rohs components on a board

Electronics Forum | Mon Feb 19 15:32:42 EST 2007 | blnorman

We use SnPb paste and bar with leaded and non-leaded component finishes. The predominant finish on components we use is Tin, there are a few NiPdAu. We've had no problems with the component finishes used in the SnPb process.

I found the right RoHS equation: SnPb - Pb + Cu +Ag = Au Have a great weekend lol

Inclusion Voiding in Gull Wing Solder Joints

Technical Library | 2012-08-30 21:24:29.0

This paper provides definitions of the different voiding types encountered in Gull Wing solder joint geometries. It further provides corresponding reliability data that support some level of inclusion voiding in these solder joints and identifies the final criteria being applied for certain IBM Server applications. Such acceptance criteria can be applied using various available x-ray inspection techniques on a production or sample basis. The bulk of supporting data to date has been gathered through RoHS server exempt SnPb eutectic soldering operations but it is expected to provide a reasonable baseline for pending Pb-free solder applications.

The Effect of Pb Mixing Levels on Solder Joint Reliability and Failure Mode of Backward Compatible, High Density Ball Grid Array Assemblies

Technical Library | 2015-01-08 17:26:59.0

Regardless of the accelerating trend for design and conversion to Pb-free manufacturing, many high reliability electronic equipment producers continue to manufacture and support tin-lead (SnPb) electronic products. Certain high reliability electronic products from the telecommunication, military, and medical sectors manufacture using SnPb solder assembly and remain in compliance with the RoHS Directive (restriction on certain hazardous substances) by invoking the European Union Pb-in-solder exemption. Sustaining SnPb manufacturing has become more challenging because the global component supply chain is converting rapidly to Pb-free offerings and has a decreasing motivation to continue producing SnPb product for the low-volume, high reliability end users. Availability of critical, larger SnPb BGA components is a growing concern
