Lengthen electric vehicle lifespan and reduce warranty costs with high reliability joining materials
Reliability is critical; we already see some manufacturers offering warranty levels of up to 8 years, with unlimited miles. Sintering technology provides a step change in reliability for power semiconductors; while for conventional soldered interconnections, the InnoLot solder alloy can more than double service life.
A fully Silver-sintered silicon die with a power cycle delta T of 100K will survive over one million power cycles. By contrast a conventionally soldered silicon die under similar conditions (Vgate 20V, 130A current, 15 seconds on, 15 seconds off, maximum junction temperature of 145°C, delta T 85°C) will fail in fewer than 12,000 power cycles.
In addition to the power semiconductor components, there are tens of thousands of conventionally soldered surface mount joints in the electronics of every car, found in the electronics control units (ECU). The InnoLot alloy can extend the fatigue life of those interconnections by a factor of two to three, depending upon design constraints.
Sintered silver technology
Sintered silver is used to increase the reliability and power density possible for the critical power conversion electronics that sit between the DC battery source and the AC motor - the traction inverter. Sintering technology enables significantly smaller, lighter and more reliable systems.
PCB & Connectors
Our wide range of chemical processes are found in all PCB manufacture and reach to the plating of alternative electronics such as connectors, substrate packages, and molded plastic parts. Lessons learned from other markets are applied to achieve the revolutionary innovation required of automotive on its road to the future.
