Conversion of Non-RoHS Compliant Materials

 

Material Conversion Analysis

Componenet Conversion
RoHS implementation presents dificult challenges for OEMs. The primary hurdle is the conversion analysis of an existing products Bill of Materials. Componenet conversion is usually much more involved than just re-specifying RoHS compliant parts. For some components, it may be difficult to eliminate the offending RoHS element (Cd, Pb, etc.) and still have the product function successfully.

Dallas Meets this challenge by cataloging, compiling and evaluating supplier certificates of compliance and materials declarations for multiple suppliers of hundreds of RoHS compliant components. Further Dallas anlyzes the reliability impact of conversion to RoHS. In many cases, converted products must be re-qualified to assess the impact of componenet changes on reliability.

Assembly Process Conversion
Dallas has the required assembly processes in place to produce RoHS compliant assemblies, however there are still many decisions for each OEM to make based on individual product requirements. These include whether to go with a mainstream SAC alloy or use a more specialty solder for temperature or mechanicals reasons. RoHS assembly conversion also includes pilot run evaluations on each converted product to establish reflow profiles, detect any product specific problems and generate functioning samples for product re-qualification and reliability testing.

Dallas has in place methods for keeping RoHS compliant and non-RoHS compliant inventories separated while accommodating both lead free and lead containing assembly.
