Paper provides a description of flux and the role of their constituting ingredients and a tin-bismuth-silver solder paste with cleanable residues. Materials Tech Aggressive form factors, reducing pitch, thinner packages, and larger die to package ratios are leading to higher package warpage during SMT reflow. Materials Tech Two solder paste chemistries and several printing parameters were evaluated in order to achieve consistent solder paste deposition across the assembly. Materials Tech How the Electrical Test industry combats requirements and provides solutions to adhere to ever changing requirements is discussed. Materials Tech This study offers a better understanding of the correlation between rheological properties and shelf life of solder paste exposed to extreme conditions. Materials Tech This paper covers a type of 'crack free' flux paste designed to inhibit cracking under extreme environments. Includes electro-chemical migration tests dew ... Materials Tech This study focused on the thermal fatigue performance and the microstructural evolution of five lead-free solders under harsh service conditions. Materials Tech The strength of solder joints is enhanced by several times, and thermal cycling performance is significantly improved. Materials Tech This paper reports results of the behaviour of Sb in a Sn-Bi alloy and consider the implications of the findings for the reliability of LTS solder joints. Materials Tech This paper discusses the need for low-temperature solders and process-ability of solder pastes with three novel alloys against the industry standard. Materials Tech |
