The easiest way is to combine microscope and digital indicator. Choose lens as shallow as possible in depth of field. Mechanism that moves up and down can measure accuracy with fine adjustment function with high accuracy. |

1.Thickness measurement | |
Transparency or semitransparent film is a condition under which the object that the sheet is in close contact with the substrate can be measured.
A transparent protective sheet is in close contact with the product on the right object.
Because the sheet is thin, I observed it at 600 times |
|
Focus on the substrate (resin) Set the value of the indicator to zero |
Focus on the top of the sheet Read the value of the indicator. This will be thick. (107 μm) |
2.Height measurement | |
(1)
Measure the IC height on the left photo.
I have observed it at 200 times because I have enough height. |
|
Focus on the substrate Set the value of the indicator to zero. |
Focus on the top of the IC Read the value of the indicator. This will be the height. (2.39 mm) |
We have two kinds of stand with digital indicator (height gauge) available. | |
Coarse fine movement stand with indicator GRS-1C125XB |
Small coarse and fine stand with indicator GR-S6C125XB |
