Hello,
I am planning to use some surface mount standoffs for my PCB design. They should be on the bottom side of the PCB, providing mechanical support for the board. The standoff I found is here: https://www.mouser.com/ProductDetail/PEM/KFB3-440-12ET?qs=l4Gc20tDgJLkVqbe/R4A0A==
However, I am confused about the Altium hole size for this standoff. Currently, I have made a pad with a hole size of 166 mil. Can someone confirm if this standoff will fit in that hole? Thank you for your time.

 

The data sheet states that the required hole size is 0.166" Dia. That matches what you are d3esigning for.

Thank you for your reply. I am a bit confused, should the marked portion be the hole size? This component should pass through the board and undergo reflow soldering, correct? I believe the inner hole size is 0.166 inches, while the threaded portion has a different dimension. This is my first time designing an SMT standoff, so I am uncertain about the correct dimensions.

 

read the datasheet... all answers to your questions are there.
find your part number or see how the part number is composed.
in this case that is

KFB3-440-12ET

if you keep reading, KFB3 is the family identifier. this product uses "combined broach/flare feature for even greater pullout performance in PC board materials"

"broach" means this is first press fit into PCB so that serrations bite into PCB. the direction of serration resists spacer rotation while applying torque
"flare" means it is then deformed using suitable tool (crimper, center punch, press die...), like a rivet...

code 440 refers to thread/hole size and for this parts size, PCB hole has to be 166mil.



so it sounds to me that the process of assembling is something like this


clearer now?

I appreciate your response and now understand it. Thank you for taking the time to explain.
