Some parts that are plated with tinned solder types are dipped in a higher Pb concentration solder to create a pressure stress barrier hindering the growth propensity of tin whiskering. However, according to the iNEMI Tin Whisker User Group's report titled "Recommendations on Lead-free Finishes for Components Used in High-Reliability Products" there is evidence that this technique may not be effective when performed on the new 99 percent tin RoHS compliant product entering the supply chain today.
E-Certa's robotic hot solder dipping technique and annealing process makes conversion from Pb free to lead solder and tin whisker mitigation a resourceful tool for military and exempted applications. E-Certa's innovative conversion technique is a fluid process with critical attention given to your product's integrity.
Requirements for this service from RoHS exempted industries-such as medical, military/aerospace- are mounting, stemming from problems with discontinued parts, long
lead times, price premium parts, and Pb free replacements with higher percentages of tin. E-Certa can convert components to a leaded solder type based on your
application that includes mitigating of tin-whiskering.
European RoHS directive may cause component inventory misalignment
(January 2007 )
Many experts predict severe inventory misalignment as a result of the European Union’s Restrictions on Hazardous Substances (RoHS) directive to eliminate lead from solder, according to experts at the Environmentally Certified Electronic Resale Trade Alliance (E-CERTA) in Bloomington, Ind.
Tin Whiskers and the Impending RoHS Conversion to Lead-Free
(July 2005)
As a part of the Lead-Free Manufacturing for Navy Systems project, the EMPF is evaluating the impact of tin whiskers on the long-term reliability and manufacturability of DoD electronics. The current, universally used tin-lead component finishes do not meet the lead (Pb) limits imposed by the Restriction of Hazardous Substances (RoHS) directive, and the July 1, 2006 compliance deadline is fast approaching. As a result, many electronic component manufacturers have chosen to switch to pure tin or one of two tin alloys – SnBi (tin bismuth) or SnCu (tin copper). However, historically, tin electroplated finishes have proven unreliable. They are cited in many well documented system failures.
