Details of the preparation of standards and x-ray procedure are given. The Au calibration curve can be prepared from any Sn/Pb composition. The Ag and Cu calibration curves must be prepared for each solder composition.", pages = "105-108", url = "http://www.ingentaconnect.com/content/sas/sas/1968/00000022/00000002/art00004", doi = "doi:10.1366/000370268774383624" }
