The less than (<) symbol is used to indicate that the test results are below the amounts indicated, which are the minimum detection limits of the laboratory performing the testing. The exception to this is for plating containing lead, where the maximum amount of lead is listed.
RoHS maximum limits (ppm): 1000 for Pb, Hg, Cr6+, PBB, PBDE (exemption: lead if solderballs are used.) 100 for Cd.
Reportable substances (if present): Antimony Trioxide, Brominated Flame Retardants, Nickel.
Weighted average = for part as a whole.
