How to fill in Number of Unique Parts?

"Number of Unique Parts" refers to the quantity of different types of components in the BOM, which is the number of various models of components used on the circuit board. It does not refer to the total number of components. For example, if a BOM contains 15 different component models (Part No.), then regardless of how many of each model are used on the circuit board, the number of individual components is always 15. Even if the total number of components on the entire board might be 21, this does not affect the calculation of "Unique Parts". You can also choose not to fill it in.

If there are any special assembly requirements, please make a note in the "special requirement" column to explain them.
