Assessing Lean Systems Using Variability Mapping, Ahmed Deif
Assessing Lean Systems Using Variability Mapping, Ahmed Deif
Industrial Technology and Packaging
A new approach to assess lean manufacturing based on system's variability is proposed. The assessment utilizes a new tool called variability source mapping (VSMII) which focuses on capturing and reducing variability across the production system. The new tool offers a new metric called variability index to measure the overall variability level of the system. Based on the mapping and the new metric, VSMII suggests a variability reduction plan guided by a recommendation list of both lean techniques as well as production control policies. An industrial application is used to demonstrate the new tool. Results show that VSMII managed to reduce …

Effect Of Gold Content On The Microstructural Evolution Of Sac305 Solder Joints Under Isothermal Aging, Mike Powers, Jianbiao Pan, Julie Silk, Patrick Hyland
Industrial and Manufacturing Engineering
Au over Ni on Cu is a widely used printed circuit board (PCB) surface finish, under bump metallization (UBM), and component lead metallization. It is generally accepted that less than 3 wt.% Au in Sn-Pb solder joints inhibits formation of detrimental intermetallic compounds (IMC). However, the critical limit for Au content in Pb-free solder joints is not well established. Three surface-mount package platforms, one with a matte Sn surface finish and the others with Ni/Au finish, were soldered to Ni/Au-finished PCB using Sn-3.0Ag- 0.5Cu (SAC305) solder, in a realistic manufacturing setting. The assembled boards were divided into three groups: one …
