Through-Hole Pad Stack Designer

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

If you open the Through-Hole Pad Stack Designer dialogue (Utilities >
 TH Pad Stack Calculator) and change Lead Shape to Square/Rectangle you 
can get into a situation where you can't enter different values for 
Height and Width for a rectangular lead.

If you enter a height 
that is higher in value than the width when you tab out both values 
change to be equal to be equal to the width.

I am guessing that 
this is the intended behaviour and the behaviour is that width should be
 greater in value than height always for rectangular leads but there's 
nothing pointing the user to this conclusion.

I am guessing that the programming might be awkard if the height and width values could be either greater than each other?

Substituting Length for Height would be more sensible I think since Length > Width.

	The hole Pad Stack Designer calculates pad shapes based on the hole size. The hole size can be either entered directly or calculated based on the lead size. There is no provision for manual pad size entry. The only way to effect a different pad size would be to change your through-hole terminal preferences. If you think about it this makes sense. It's repeatable since it follows rules. There's no way to reconstruct a manual pad size entry.

	Hi Jeff, thanks for the reply, but I was talking about the entry for the lead size where the user can input a rectangular lead size.
