Hello,

I refer the AN79938 Design Guidelines for Cypress Ball Grid Array (BGA) Packaged Devices (Document No. 001-79938 Rev. *E).

Is the S70GL02GT11FHB010 64-FBGA (13 x 11mm, 0.6mm ball diameter) package Solder Mask Defined or Non-Solder Mask Defined openings?

Could you provide the recommended Solder Ball Pad Design for S70GL02GT11FHB010?

Best Regards,

Naoaki Morimoto

Hello Morimoto-san,

In regards to the S70GL02GT11FHB010 64-FBGA (13mm x 11mm, 0.6mm ball diameter) package, Cypress offers solder mask defined (SMD) pad on the package side.  However, Cypress recommends NSMD configuration for PCB land pad design for most applications,

as the NSMD configuration results in a stronger bond between the solder pad and the ball.

Hope this helps...

Thank you and regards,
