What is Ecopack?
Ecopack is the registered trade-mark of ST for its component development and programs implementation for solutions leading to environment friendly packaging and packing materials. Ecopack products are Lead-free and RoHS compliant. This means mainly lead (Pb) will be replaced (less than 0.1% lead in any base material). Base materials are for example the surface finish layer, or solder balls. ST is introducing Ecopack products with the capability to perform board assembly with Pb-free solder. RoHS is considering exceptions, when the alternative to Pb-based technology is not available, like in the case of high Pb-content (>85%) soft solder die attach of power devices. Also in this case, the products are called Pb-free ? which essentially means RoHS compliant.
