The data we have is from an IBM report. Below 100�C the SAC reliability is almost double that of SnPb (-40 to 100�C thermal cycle). When the upper end temp is increased to 125�C the reliability drops to 75% of SnPb. I'd like to see the data that s

We are building a plasma diagnostic to monitor MHD phenomena in tokamak. As part of the development, we need high-voltage, high-power RF capacitors to tune and match an inductive load. This application is similar to a small induction heater, with t
