CST Global has successfully installed and commissioned an Opto Systems VVSP4000, automatic pick-and-place, visual inspection machine in its fabrication facility in Blantyre, Glasgow (Scotland). The machine performs a visual inspection of both the top side and facets of laser diode chips.
The company says the automatic pick-and-place, visual inspection machine increases their inspection capacity in line with other production processes and is fed from recently commissioned, automatic bar stacker and automatic scribe and break machines.Â
The Automatic VI machine picks the singulated laser bars from tape, sorting out the working DFB laser chips on each bar, before placing them back on either tape or gel pack. The current takt time â€" or process time â€" is 4.5 s per laser chip, meaning the automatic inspection capability increases the company´s test capacity by more than half a million laser chips per month.
The Automatic VI machine will recognize the laser ID number, with an option to record an image of each laser for reference. The process is repeatable and consistent, with a full audit trail. Furthermore, wafer batch quality can be tracked.
