Keeping moisture out of electronic components before they enter the manufacturing process is a critical concern for the automotive sector.  With the shift in automotive technology being from mechanical to electronic, it is now the performance of the electronic components that need to be completely reliable. The consequences of failure can, of course, be devastating. Melexis overcomes the problem with Totech Dry Tower. 

Brose had long wanted to automate the storage of their component reels when they visited Totech at the SMT trade fair in Nuremberg in May 2015, and discussed in depth the automation possibilities at the company’s Hallstadt location. The resulting Dry Tower material logistics installation is fully automated so there is no need for any manual handling of the component reels between storage and actual use on the assembly line.

HS Elektronik Systeme, a Collins Aerospace company with more than one hundred employees, is an electronics technology specialist with over thirty years of experience in the aerospace industry. When the warehouse at their Nördlingen site was to be connected to a material management software, an evaluation process of automated dry storage systems available on the market began. 

After several months of intensive project work with the ifm team, SuperDry Totech has created a materials Dry Tower storage concept for the company which meets the technical requirements of modern SMD production and, at the same time, offers great savings potential.
