Focus on Lead-free Defects in the IPC-7095 Revision

Reading time words. The focus of the IPC revision is on lead-free BGAs, land-pattern design and troubleshooting of design- and process-related defects. As the chairman of this committee, I invite your comments as this document goes through this revision. There are two commonly used methods for designing BGA lands - solder-mask-defined and non-solder-mask or copper defined. Solder-mask-defined lands are not desirable because they impact reliability adversely. IPC conducted a survey to determine how prevalent this practice is, the reasons why component suppliers use solder-mask-defined lands and user experience with solder-mask-defined lands. More than individuals responded to the 16 questions regarding solder-mask-defined and metal-defined lands.
