8. Electronics design

Group 1 (Ito-Yamada)

This is the group assignment of the week.

• Use the test equipment in your lab to observe the operation of a microcontroller circuit board;

I use a micrometer to identify the problem areas on the board that are not working in individual assignment8.

Testing Board

Testing

Micrometer: HIOKI 3244-60

I measure readings from the areas enclosed by the same colored circles, respectively.

Measuring voltage

Measuring conductivity

The micrometer displays “OF” (Overflow). This indicates that this part is not conducting properly.

I found that the soldering has failed at the spot indicated by the arrow.

I learned the importance of carefully soldering in this process.
