Green Packaging and Halogen-Free

The Lead-Free movement is linked with the so called “Green” packaging issue of which it is an integral part. In green packaging, the endeavour is to remove all toxic substances from the package, and this includes notably the bromine-antimony complexes now universally applied as additives to the mold compound, in order to guarantee the required fire retardancy.

Melexis defines “Green” products as those which are:

  • RoHS compliant

  • AND are Halogen-Free according to IEC61249-2-21 definition

    • 900 ppm maximum Bromine

    • 900 ppm maximum Chlorine

    • 1.500 ppm maximum total Halogen (Br+Cl)

  • AND contains less than 900 ppm Antimony trioxide (Sb2O3)

Any material used in the assembly process of semiconductor packages is considered to follow the limits as mentioned in the table below for “Lead-Free”, “RoHS” and “Green Packages”:

Limit  Pb Free RoHS Compliant Green Package
Pb 1.000 ppm 1.000 ppm 1.000 ppm
Hg  N/A 1.000 ppm 1.000 ppm
Cd N/A  100 ppm 100 ppm 
Cr6+ N/A 1.000 ppm  1.000 ppm 
PolyBrominated biphenyl  N/A 1.000 ppm  1.000 ppm 
Polybrominated biphenyl ether  N/A 1.000 ppm  1.000 ppm 
Bis (2-ethylhexyl) phthalate (DEHP)  N/A 1.000 ppm  1.000 ppm 
Butyl benzyl phthalate (BBP)  N/A  1.000 ppm  1.000 ppm 
Dibutyl phthalate (DBP)  N/A  1.000 ppm  1.000 ppm 
Diisobutyl phthalate (DIBP)  N/A  1.000 ppm  1.000 ppm 
Bromine  N/A  N/A 900 ppm 
Chlorine  N/A  N/A  900 ppm

N/A stands for not applicable.
