3. Comparative analysis of project import efficiency and manual testing
artificial | SRC functional test system | |
Detection speed | 180:600S/PIC | 60'180S/PIC |
Inspection record | No records or manual records | Automatically record into the database for easy query and data backtracking |
Inspection quality | Manual testing requires connection, etc., there may be connection errors, and the test time is relatively long, which is prone to human factors, resulting in missed reports. |
Automatically judge according to the settings, without the influence of human factors |
Test suitability | No unified device can detect all DUTs |
- One system can detect all the tested objects |
Detection efficiency | Working for a long time, people are easily fatigued, resulting in a decrease in efficiency and also affecting the quality of inspection |
24 hours continuous work |
Fourth, equipment import cost recovery cycle accounting
project | before import | after import |
Single detection time (seconds) | 3 minutes to 10 minutes | 1 minute to 3 minutes |
8 hours capacity per station | 6 to 20 | 20 to 60 |
Save 2 to 3 people after importing equipment |
