Specific work includes equipment maintenance, overhaul and communication with suppliers. Maintenance is divided into hardware maintenance, daily maintenance, weekly maintenance and monthly maintenance. Usually, suppliers have maintenance manuals and operation manuals, followed by software maintenance. The core of AOI is software, so the main job is to maintain your test program. AOI should balance misjudgment and missed detection, so it needs to adjust and update the program frequently. Have a nice day at work.
