Wirebond optical field detection brings a revolutionary breakthrough to the traditional gold wire detection. It supports full on-line inspection. Through the application of optical field technology, the hidden trouble caused by abnormal Wirebond process section can be eliminated in advance, the back-channel package yield of the chip can be improved, and the loss of the back-end PCBA section can be avoided.


Scenario scheme:

1. Chip type: Gold wire diameter :18≥μm; Gold wire spacing :2 times wire diameter; Number of gold thread layers: ≤2 layers;

2. The chip size can be checked:≤5mmx5mm

3. Detectable line height range:100μm ≤H≤ 600μm

4. Defect type: multi-line, parallel, ball deviation; Less line, broken line, ball up, foot up; Chip dirt, scratches, edge collapse, gold line collapse, tight line, etc.;

5. Detection accuracy: over detection rate: ≤0.1% Missing detection rate: ≤0.1%

6. High detection efficiency:UPH>20000pcs

The VOMMA optical field screen defect 3D detection scheme can accurately locate the level information and 3D orientation of the defect through a single photo, fundamentally prevent the forced scrapping problem caused by screen defects, and help manufacturers improve the quality and competitiveness of products.


Scenario scheme:

1. Type of detectable screen film: polarizer、LCD、OLED、Mini LED

2. Defect type: scratches, bubbles, filaments, dust, broken spots, etc

3. Can be chip gold wire detection, polarization film layer detection

4. No need to cast light, single photo, multidimensional display

5. Z-axis repetition accuracy of 0.5μm

Light field 3D modeling scheme can use light field technology to quickly and accurately reconstruct 3D models, and provide important reference and support for design, manufacturing, scientific research and other fields.


Scenario: Research university laboratory

1. Micro, thin and transparent detection of 3D data acquisition in optical engineering, integrated circuit, intelligent manufacturing, biological cytology and electronic engineering;

2. It can be used in stereo photography, stereo microscopy, stereo image production;

3. It can detect chip gold wire, polarizing film layer, etc

4. No need to cast light, single photo, multidimensional display;

5. Z-axis repetition accuracy of 0.5μm.
