    Question about CY7C65642-28LTXCT pins for soldering




      [Q1]  About CY7C65642-28LTXCT pins, Is it necessary to solder all pins? (Without heat dissipation pad)
      Especially, there are some not using pins(floating), By covering the pad with a resist and not opening the metal mask, it is possible to prevent a short circuit between terminals during component mounting.

      [Q2] Does the performance of parts change depending on whether or not the open pins are soldered? (Without heat dissipation pad)
      Example: Doesn't D+/D- use for 1 port, so does the performance change when the pins are floated?
      (Open on the board even if solder is applied)


      Best Regards
