MOSFET Power Module Test Bench
The MOSFET power module test bench is made for the power module electrical test, composed of MOSFET power, made to be mounted in alternator-starters.
The power modules are conveyed, from the assembly and welding machines, onto carriers thanks to a belt transfer composed of different conveyor sections, an elevator at the entrance and exit of the machine, storage stops and an indexing station of the carriers.
The power module’s Datamatrix identification code allows complete traceability of the tests and results associated with each of the products.
When a carrier arrives at the unloading station, a robot equipped with a gripping hand takes the product by suction and deposits it on one of the two rotating plates.
Each power module undergoes electrical tests at 3 dedicated stations on the trays. The connection to the product is made via a higher test cassette allowing the connection of the measurement signals and via a lower test cassette allowing connection of the power. Each test station is associated with a dedicated test bay.
The successfully tested products are unloaded from the rotating plates by the robot and loaded into thermoformed trays at a stacker / destacker.
