Magcam is the only high tech company in the world offering a unique Magnetic Field Camera (Magcam) technology system. The Magcam magnetic field camera measurement platform is an advanced digital matrix magnetic field sensor that measures three-dimensional magnetic field maps with high spatial resolution at high speed. Applications include R&D, in-line production inspection and incoming and outgoing quality control of permanent magnets and magnetic assemblies,....
The purpose of the project was to miniaturize the camera size from a total size of 85x56mm to a size of 25x25mm. The system contains an ASIC of 15x15 mm which has to be bonded and glob topped. Besides the high density, tolerances and flatness requirements a FR4 cavity was laminated during PCB production to be filled with glob top afterwards and diced to 250um above the ASIC. A production tool for verification of all die assembly steps on the bare PCB was designed and PCB production with extremely high yield are achieved.
