Integration of the NIST and SURDAT Databases on Physical Properties of Lead-Free Solder Alloys
The electronic SURDAT database published in 2007 (available freely from the website www.imim.pl/english) is being integrated with the NIST database (available freely from www.boulder.nist.gov/div853/lead_free/solders.html) to provide a single source for data on lead-free (Pb-free) soldering alloys. The NIST database was developed to support circuit board designers, and so it is focused primaril...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولA Comparison of Lead-Free vs. Eutectic Solders
T he use of lead in the electronics industry today accounts for approximately 7% of total lead consumption.' The single largest use of lead is in the manufacture of storage batteries, which accounts for 60% of the total lead produced.2 The use of lead is closely regulated in plumbing, paint and gasoline industries. Currently, the electronics industry has been exempted from the existing requirem...
متن کاملEffects of Lead-Free Solders on Flex Performance
Ceramic capacitors have proven themselves very reliable with extremely low failure rates. As processes continue to improve, reliability of the dielectric also continues to increase. This increase in the reliability of the dielectric has caused other categories to emerge as the main contributors to the overall failure rate. A recent review of field failure analysis of surface mount MLCCs, has sh...
متن کاملNovel Rare-Earth-Containing Lead-Free Solders with Enhanced Ductility
Several lead-free material systems are available as replacements for traditional lead-based solders in microelectronic packaging, including near-eutectic combinations of tin-rich alloys. Although these materials have superior mechanical properties as compared to the Pb-Sn system, much work remains in developing these materials for electronic packaging. Small additions of rare-earth elements hav...
