Does my application require RoHS compliance?
If your question deals with the requirement of RoHS compliance for your application (as in the case of the pre-lit Christmas tree), there are a number of services that can help. I’m not qualified to interpret the legalese of RoHS, so visit Dionics for a simple self assessment to determine if your application needs to be RoHS compliant. Other resources include Newark InOne and EMA Design Automation.
