Figure 14: CSP10: Layout recommendation
Recommendations for reliable soldering of solder balls:
• Use a pad layout similar to the one shown in Figure 14. Notice that all tracks should go underneath the solder mask area.
• Do not connect any pins direct pin to pin inside of the opening of the solder mask.
• In case of the conductors are with a Au-Ni surface finish the preferred landing pad design for the solder balls will be covering the
round landing pad with a gold surface finish as a solderable area only.
