Pin size defect detection diagram
| Code | Bad Name | Actual bad diagram |
|---|---|---|
| a | Pin spacing | Characterization：Through the structured light and the lens with optical prism, the perfect imaging of the front and two sides of the chip is achieved. In turn, the key dimensions are acquired one by one through a stable algorithm. The detection of each dimension of the chip is realized. |
| b | Top surface of the device to the middle of the coarse pin size | |
| c | Fine stitch length | |
| d | Pin span distance | |
| e | Pin tilt angle | |
| f | Coarse stitch width | |
| g | Fine stitch width | |
| h | Component thickness |
| Test Type | Each detection of bad items | |
|---|---|---|
| Detection of geometric dimensions | Print position, print angle, print margin, character offset |
|
| Inspection of print quality | Contrast, underprint, overprint, overall size |
Appearance defect detection - Printing defect
Pre-process forked products, often with internal hollow cores, etc.
Defects generated during the injection molding process have trustworthiness potential.
The edge of the chip-plastic body is bumped and there is a quality hazard.
The chip is processed and manufactured with hard damage.
DIP series appearance inspection equipment
