The Use of SAC Solder and Pb-Free Lead Materials in the Repair Scenario

摘要

Much work has been done involving the introduction of RoHS and WEEE Directives across the European Union and the world. Although the use of Pb is limited in new products and equipment, older Pb-containing materials can continue to be used for repair of existing systems. As time progresses, these older Pb-containing materials will need to be repaired using Pb-free components and solders. This paper addresses the concerns of repair centers, which must rework these boards using Pb-free components and materials.
