How to measure height and thickness with a microscope?

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.

厚み測定
   
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

厚み測定
   

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)
It is a condition that you can measure the object on which the step can be projected on one screen.

 

Measure the IC height on the left photo.

 

I have observed it at 200 times because I have enough height.

高さ測定
   

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.
