Hella Electronics: Electronic modules EOL testing at Low and High Temperature
Hella Electronics is a member of Hella group. The main business focus is production of different electronic modules for cars.
Challenge: EOL test of high quantity of produced breaking control PCBs at low and high temperature with communication with the Hella test system and appropriate interfacing to the existing MES system. Each of produced PCB should be tested, production tracking is obligatory.
Inea designed and implemented very innovative solution, called LTHT45 Test Line.
- In-line with the production line:
- Circular line with parts loading and unloading stations
- Mistake proofing at loading of parts
- Visual indication of NOK parts at unloading station
- Bar code identification of parts
- LT parts testing at temperatures down to -32 °C
- HT parts testing at temperatures up to 87 °C
- Variable climate chamber temperatures
- Labelling of tested parts
- Integration with the external Hella testing systems
- Integration with plant iTAC MES system
Basic technical data:
- Cycle time: 15s/part, capacity: 240 parts/h
- Low temperature chamber (-32 °C), High temperature chamber (87 °C)
- Pel=30 kVA, Voltage: 400 VAC, Weight of equipment: 6.000 kg
- Footprint: 3m x 7m
- Control system based on Siemens S7 Simatic PLC, Cognex DataMan, Print&Apply system
We should emphasize that project was realized in close and good cooperation with the customer. User requirements and technical solutions were deeply discussed. Project implementation time from contract sign to system handover was just six months.
Performance of the built system was according to the user requirements. Customer was very satisfied with the technical solution and the relationship. New projects are planned.
