    Pad pitch of CYBT-343026-01 and CYBT-353027-02

    KeTa_1341526

      Hello,

       

      Pad pitch is defined in the datasheets of CYBT-343026-01 and CYBT-353027-02.

      - CYBT-343026-01

             Datasheet: https://www.cypress.com/file/381006/download

       

             Page.6: Table 2 [Pad Pitch] 1.22mm

      - CYBT-353027-02

             Datasheet: https://www.cypress.com/file/416356/download

             Page.6: Table 2 [Pad Pitch] 1.05mm

       

      However, in [Table 3. Module Solder Pad Location] of each data sheet, the pitch of the following pad is different from the value defined above.

      - CYBT-343026-01

             Page.8: Table 3. Module Solder Pad Location

                    Pad 7 - Pad 6 = 12.35mm - 11.14mm = 1.21mm

                    Pad 18 - Pad 19 = 12.35mm - 11.14mm = 1.21mm

      - CYBT-353027-02

             Page.8: Table 3. Module Solder Pad Location

                    Pad 8 - Pad 7 = 1.88mm - 0.82mm = 1.06mm

       

      Is this a problem?

      When designing a solder pad, should I design it according to [Table 3. Module Solder Pad Location]?

       

      Best regards,
