Sn—based lead—free solders such as Sn—Ag—Cu, Sn—Cu, and Sn—Bi have been used extensively for a long time in the electronic packaging field. Recently, low—temperature Sn—Bi solder alloys attract much attention from industries for flexible printed circuit board (FPCB) applications. Low melting
Low temperature solder alloys are preferred for the assembly of temperature—sensitive components and substrates. The alloys in this category are required to reflow between 170 and 200oC soldering temperatures. Lower soldering temperatures result in lower thermal stresses and defects, such as ...
In this study, a Sn—Bi composite solder paste with thermosetting epoxy (TSEP Sn—Bi) was prepared by mixing Sn—Bi solder powder, flux, and epoxy system. The melting characteristics of the Sn—Bi solder alloy and the curing reaction of the epoxy system were measured by differential scanning calorimeter (DSC). A reflow profile
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 245℃ which is almost 30℃ 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.
Test equipment for high current EV battery -- does anyone know what equipment I can use to test high current EV batteries? We want to expand our testing capabilities and standardize all our battery testing. Looking for feedback from anyone who has used test equipment for electric vehicle batteries. Thanks!
