Rolls Frequently Asked Questions

Are Rolls Products RoHS compliant?

No, we opted for reliability rather than a fictitious hazard posed by our circuit boards. NASA and government entities do not allow lead free solder in mission critical products for reliability reasons. Lead free solder causes shorts and failures especially as time passes. At Rolls we have been scrutinized by OSHA twice for possible lead contamination and received clean findings both times. Also all materials used in making Rolls products are in compliance with current manufacturing standards. WARNING: The solder used in Rolls products contains lead, a chemical known to the State of California to cause birth defects and other reproductive harm. Please wash hands after handling internal components and circuit boards and avoid inhalation of fumes if heating the solder. Always a wise precaution.
