20090310318 | ATTACHING A LEAD-FREE COMPONENT TO A PRINTED CIRCUIT BOARD UNDER LEAD-BASED ASSEMBLY CONDITIONS - A technique for attaching components to PCBs involves providing a lead-free component and a PCB. The lead-free component has a package and lead-free component contacts, and the PCB has PCB contacts. The technique further involves disposing (e.g., printing) solder paste between the lead-free component contacts of the lead-free component and the PCB contacts of the PCB. The solder paste includes lead (Pb), a second metal (e.g., tin (Sn) and a third metal (e.g., Bismusth (Bi)). The technique further involves applying heat to melt the solder paste and form solder joints between the package of the lead-free component and the PCB contacts of the PCB. Such a technique is capable of concurrently mounting lead-free components as well as lead-based components to a PCB under lead-based assembly conditions (e.g., a temperature environment which does not exceed 230 degrees Celsius). | 2009-12-17 |
