As a rule, I never place my thumbs where they can be hit with a hammer.
That's a technical dropping.

Dear collegues,

I have heard of a thumb rule, never place them along and close to the
edge. Hence, we place them (when suitable) in the center. I have
forgotten why this rule. Was it because of vibration nodes, warpage
during soldering, tempcycle issues or what? Is there a IPC standard or
other reference?

Inge
