High Melting Lead-Free Mixed BiAgX Solder Paste System
Although lead-free soldering has been main stream in the industry since 2006 with the replacement of the eutectic SnPb system by the SnAgCu system, the development of drop-in lead-free alternatives for high melting high lead solder alloys is still far from mature. The BiAg alloy exhibits acceptable bulk strength, but very poor ductility and wetting. Therefore, it is not acceptable as an option....
متن کاملLead-free Solder Assembly
Until non-lead solder conversion is mature, the evaluation of materials and components is likely to identify trade-offs. The performance of the no-clean andwater-soluble solder pastes that were tested varied widely. Ultimately each company will need to determine which attributes are most important for their product line. Also components needed for a product may not be currently available as lea...
متن کاملInfluence of halogen-free compound and lead-free solder paste on on-board reliability of green CSP (chip scale package)
In the past few years, many studies have reported on the formula of solder metal alloy materials. This paper discusses the influence of organic materials characters, the decomposing rate of flux in lead-free solder paste and coefficients of thermal expansion (CTE) of halogen-free mold compounds during the on-board reliability test, and the failure mechanism in both 63Sn/37Pb and Sn–3.5Ag–0.5Cu ...

متن کاملLead-free Solder Assembly: Impact and Opportunity
There has been major interest in Lead-free soldering within the electronics assembly industry for the last several years, and this will continue with the agreement on the language and implementation dates of the WEEE/ROHS legislation in the EU. This paper will focus on several topics critical to the implementation of lead-free soldering. These topics include the impact of Tin-silver-copper as t...
