"7. Lead in high melting temperature type solders (i.e. lead based solder alloys containing more than 85 % lead)" This exemption is in the amendments to the RoHS annex and in the original Annex (was "Tin-lead based" originally). Also in the amendments are specific exemptions for microprocessors and Flip Chips. "14. Lead in solders consisting of more than two elements for the connection between the pins and the package of microprocessors with a lead content of more than 80 % and less than 85 % by weight." "15. Lead in solders to complete a viable electrical connection between semiconductor die and carrier within integrated circuit Flip Chip packages." If the part/solder falls within any of the three categories it is exempt and can be used in a product that is non-exempt.

For e.g. a BGA component can be RoHS compliant even if the 1st level i= nterconnects have high lead solder because there is a specific lead exempti= on for this application....correct? now is there a document that says that = high lead-solder can be used for 1st level interconnects ONLY for certain p= art types (for e.g. BGAs and some others?) to be RoHS compliant, or it is i= ndependent of the part type? Can this BGA now be used in a non exempt application assembly and still not= violate the RoHS compliancy of that assembly? We have a particular component (Not BGA) where a high Pb solder will have t= o be used so that the 1st level interconnect will not melt when exposed to = LF soldering temperatures during assembly. The final assembly is a non exem= pt product. Regards, Amol Kane M.S (Industrial Eng.)
