Abstract

Electronic equipment industries are interested in evaluation of the life of new soldering lead-free materials used for the implementation of electrical interconnections and consequently in new soldering process. In fact, they have to guarantee RoHS conformity assessment of the electrical and electronic devices, in terms of restriction of the use of hazardous substances with the aim to protect human health and environment. Materials such as lead-free alloys are RoHS compliant but the consumer requires evidence that such solders are equally reliable as tin-lead solders, for the proposed use and lifetime of the product. In order to support new International Standards and fill the technology knowledge gap, the paper proposes a new multi-stress accelerated life model able to evaluate the life of tin-silver-copper alloy under combined and sequential tests: cycling climatic and random vibration tests.
