The 2015 Delegated Directive, often called RoHS 3, added these four phthalates to the original six substances. The same ten substances and limits apply under UK RoHS.
Lead-free throughout. All solder paste and components used in our manufacturing are lead-free (Pb-free) and meet the relevant national and international standards.
