Hi Kengo,

Please see the link below going over how to design a land pattern/stencil for several of our package types (including this SSOP-24).

Hi Bryan,

Thank you for your reply.

This document is only the land pattern information.
Could you tell me how to design stencil design?

Sincerely.
Kengo.

Hi Kengo,

Apologies for the confusion. While we do not have an exact one available for the 24DBQ package, you can utilize the 16pin DBQ stencil and just extrapolate it to this 24 pin version as the spacing and dimensions will be identical (just a few more pins).

Hope this helps!

Bryan

Hi Bryan,

Thank you for your reply.
I understood.
I'll use 16pin DBQ PKG information.

Sincerely.
Kengo.
