Is an automatic IR tester worth it?
Automatic machine vs semi-manual vs manual cell IR testing :
Type | Equipment | Equipment cost | Est. human time /cell | Max cells /day | Cost /cell | Comments |
Automatic | TOB-1810B-21 | ~8k€ | Feeding ~2s
Testing 0.7s
Can be done in parallel so test=0s | 10k~15k | 25/3600*2 = 0.014€ /cell
Machine depreciation in a few 1000s cells | Fast and reliable.
Probably a lot of down-time for the machine |
Semi-automatic | Custom testing machine + manual cell feeding and sorting | ~2k€ + custom machine development | Feeding ~2s
Testing 1s
Sorting ~3s
Sequencially | 3k~6k | 25/3600*6 = 0.042€ /cell | Repetitive and error prone
Dev is time & cost consuming
Reliability can be problematic |
Manual | IR tester + cell jig + manual sorting | ~1k€ + jig development | ~10s | 1.5k~2k | 25/3600*10 = 0.069 € /cell | Very repetitive and error prone |
