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