The International Electronics Manufacturing Initiative (iNEMI) High-Reliability RoHS Task Force has published guidelines regarding assembly processes and reliability requirements for RoHS subassembly modules. In a statement, iNEMI notes that with current RoHS exemptions for high-reliability electronics, it is possible for electronic assemblies to contain lead and still be RoHS-compliant. Manufacturers taking the lead exemption will continue to require tin-lead compatible component for their products and may also use subassemblies such as hard disk drives and power modules that may or may not be lead free.
The issue has become a big concern for those in the exempt industries of aerospace, defense, medical equipment and telecommunications, since many of their components are now lead-free. Thus, in many instances leaded components and lead-free components will exist in the same subassembly. “It is very likely that manufacturers will use subassemblies that contain both tin-lead and lead-free components, which causes reliability concerns due to the differences in processing temperatures and materials,” says Thilo Sack, principle engineer, corporate technology at Celestica Inc., and co-chair of the iNEMI High-Reliability Task Force.
The guidelines are intended to help manufacturers producing high-reliability products to work through these issues effectively.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
