Caution (1) (2) Do not carry out soldering on the island section in the four corners of the package (the section shown on the lower surface drawing with diagonal lines) with the aim of increasing mechanical strength. The island section exposed on the package surface (the section shown on the upper surface drawing with diagonal lines) must be used as (Note 6) below while electrically insulated from outside. Note 6: Ensure that the island section (the section shown on the lower surface drawing with diagonal lines) does not come into contact with solder from through-holes on the board layout. · When mounting or soldering, take care to ensure that neither static electricity nor electrical overstress is applied to the IC (measures to prevent anti-static, leaks, etc.). · When incorporating into a set, adopt a set design that does not apply voltage directly to the island section. 9 2002-09-11 TB6552FN/FL Package Dimensions Weight: 0.07 g (typ.) 10 2002-09-11 TB6552FN/FL Package Dimensions Weight: 0.05 g (typ.) 11 2002-09-11 TB6552FN/FL RESTRICTIONS ON PRODUCT USE 000707EBA · TOSHIBA is continually working to improve the quality and reliability of its products.
