Wafer inspection scheme

Wafer Inspection Scheme Shenzhen SPOTECK Technology Co., Ltd., SPOTECK has been focusing on machine vision inspection for 13 years.

There are a lot of testing cases, wide application areas, free sampling, development of testing programs, rapid outbound.

 

1. Contents and requirements of testing

Measure workpiece area:

Appearance and Dimension Detection of Samples 1.44mm in Length, 1.43mm in Width and 1.65mm in Height

Detection Contents: Damage, cracks, stomata, poor nickel layer

1: Bottom Positive Detection Appearance

2: Side Positive Detection Appearance

3: Side Positive Detection Appearance

4: Side Positive Detection Appearance

5: Side Positive Detection Appearance

6: Top Positive Detection Appearance

Note: The above detection items need to be clearly visible under the image to detect.

Detection efficiency: 250-350 pieces per minute (according to sample feeding speed).

Division of work: Subdivide the detection steps according to the detection content.

IV. System Installation Requirements:

Inspection space for equipment placement: Separately installing SP visual inspection system at the pipeline side, it is necessary to ensure that there is enough space to install the equipment.

Ambient temperature: 0-50 degrees Celsius;

Air humidity: below 90% RH;

Electronic jamming: Provide equipment with less electronic jamming.

Power supply: 220V, 50Hz AC, less than 1KVA power consumption, air pressure 0.35-0.7MPa

Above is the wafer detection scheme, the main contents of detection are breakage, cracks, pore, poor nickel layer and size.
