Seica will attend the Automotive Battery Tech, event in Berlin where selected executives from well-known companies jointly discuss with worldwide experts about best practices, trends, current projects and issues from automotive EV sector and pave the way for long-term planning.
Seica’s Speech – The electrical test of welding and bonding connections as a fundamental step of the battery pack manufacturing process – will be on display 28/09/ 11.30, Luca Corli, Director of Sales, will present Seica expertise and best Flying probe test solutions suitable for all battery packs.
Battery packs for today’s EV market are typically manufactured by interconnecting several cells in series and/or parallel to achieve the required voltage and current values for different applications. The connections between the cells are made through wire bondings, busbars, flexible and rigid PCBs or other methods which utilize solder joints to make the electrical contact, and the quality of those connections, in terms of electrical resistance, is a key factor to allow the battery pack to work properly. Seica speech offers an overview of the bonding/welding scenario; in particular the issues created by bad solder joints, impact on manufacturing costs, design for testability suggestions and practical solutions to perform electrical test based on real Kelvin measurements, with a resolution in the range of µOhms, performed via physical contact of the electrical probes of automated mobile probe test systems.
