Separation and Control of Non-RoHS Compliant Materials


Truly RoHS Compliant Components

Separation and control of different types of components is critical to assure that a given product is truly RoHS-compliant. Currently, there is no universal agreement within the supply chain to designate unique part numbers for RoHS compliant components vs. non-RoHS compliant items. Many component manufacturers choose to identify compliant parts by lot code or date code instead of unique part numbers.

Since no industry-wide supply chain identification standard exists for RoHS compliance, to achieve this goal, Dallas has instituted procedures to distinguish between RoHS-compliant and non-compliant components. This ensures that each compliant OEM product contains only compliant components and is assembled with lead-free soldering.

Dallas Ensures RoHS Compliance with the Following Steps:
• BOM “scrubbing” to determine current compliance of each component.
• Research and specification of alternate components.
• Redesign of the product to adapt to new components.
• Implementing new assembly processes.
• Prototyping of redesigned assemblies.
• Reliability testing of new, compliant designs.
• Production.

It is nearly inevitable that some amount of non-compliant material will be stranded as excess and obsolete inventory because of this transition. Dallas works closely with OEMs to implement changeover strategy.
