Transition to lead free solder stations in electronics packaging has raised issues regarding process, metallurgy and reliability m assemblies. In regards to soldering, lead has been used for thousands of years in a wide range of applications. Conventional eutectic or near eutectic tin-lead solder compositions have been used for virtually all soldering applications in electronics assembly for the last 50 years, In the electronics assembly process, a majority of commercial rework applications and some low density board assembly processes require hand soldering stations (...) This paper describes an attempt to quantify both qualitative and quantitative data that can aid in the evaluation of lead free soldering irons.

For high-density electronic packaging,the application of flip-chip solder joints has been well received in the microelectronics industry. High-lead(Pb) solders such as Sn5Pb95 are presently granted immunity from the RoHS requirements for their use in high-end flip-chip devices, especially in military applications. In flip-chip technology for consumer electronic products, organic substrates have replaced ceramic substrates due to the demand for less weight and low cost. However, the liquidus temperatures of high-Pb solders are over 300°C which would damage organic substrates during reflow because of the low glass transition temperature. To overcome this difficulty, the composite solder approach was developed...

As the traditional eutectic SnPb solder alloy has been outlawed, the electronic industry has almost completely transitioned to the lead-free solder alloys. The conventional SAC305 solder alloy used in lead-free electronic assembly has a high melting and processing temperature with a typical peak reflow temperature of 245ºC which is almost 30ºC higher than traditional eutectic SnPb reflow profile. Some of the drawbacks of this high melting and processing temperatures are yield loss due to component warpage which has an impact on solder joint formation like bridging, open defects, head on pillow.
