  • There are also steps to take when setting up your reflow profile to reduce the amount of heat exposure to the solder paste during the reflow process and prevent graping. (wikipedia.org)
  • The predominant use of RoHS compliant lead-free solder alloy assemblies has presented some further challenges to BGAs including "head in pillow" soldering phenomenon, "pad cratering" problems as well as their decreased reliability versus lead-based solder BGAs in extreme operating conditions such as high temperature, high thermal shock and high gravitational force environments, in part due to lower ductility of RoHS-compliant solders.
