In addition, 90iSC offers automotive manufacturers, many of whom have not yet transitioned to lead-free materials, an alloy that delivers creep resistance, thermal cycling and thermal shock performance, as well as drop and vibration test results equal or superior to SnPb solders.
For example, there are cases in which a project specification calls for SnPb or eutectic solder paste, but the assembler receives BGA components with Pb-free solder balls.
For companies that manufacture products that must have high-reliability and long-service-life, the rationale for staying with SnPb assembly is very clear--the reliability of Pb-free assembly has not been sufficiently demonstrated for long-life, mission-critical applications," said Ken Stuchlik, SCN processor and I/O technical manager for Lucent Technologies, and co-chair of iNEMI's SnPb BGA Availability Task Group.
This risk analysis permitted a cost trade-off consideration to determine whether to refinish the parts with SnPb or with a modified process for mixed lead and Pb-free components.
For new product developments, medical OEMs should consider the impact of SnPb component obsolescence.
Provided options in the specification if SnPb reference samples are not used or available for baseline whisker length comparisons.
NiPdAu is accepted by the semiconductor market, maintains excellent performance and reliability, and is compatible with existing SnPb assembly processes.
While electroplated SnPb surface finish exhibits good solderability and is virtually immune to tin whisker growth, a termination plated with pure tin is very likely to spawn tin whiskers, usually in months or years after plating (FIGURE 1).
The problem, according to Cirimele, is assemblers are accustomed to SnPb, which means good wetting.
LEADTINNING HAS experienced a surge in popularity recently for a number of reasons, a leading one being the effect of RoHS on SnPb lead-finished component supplies and high-reliability electronics manufacturers' need for these hard-to-find components.
Yes, it is "old"; HASL came about in the mid '70s and was quickly adapted as "the way" to finish through-hole PCBs with a SnPb coating.
