TN1208 Technical note Tape and reel shipping media for STM8 and STM32 microcontrollers in TSSOP and SSOP packages Introduction TSSOP and SSOP packages can be supplied in tape and tube shipping media. The reels have a 13” typical diameter. The types of reel used are in plastic either anti static or conductive, with a black conductive cavity tape. The cover tape is transparent anti static or conductive. The devices are positioned in the cavities with the identifying pin (normally Pin “1”) on the same side as the sprocket holes in the tape. STMicroelectronics tape and reels are compliant with EIA 481 and IEC 60286-3 standard specifications. Table 1 lists TSSOP and SSOP packages available for STM8 and STM32 microcontrollers, as well as the corresponding shipping media. Table 1.

DocID027436 Rev 1 5/13 12 Leader and trailer tape specifications 2 TN1208 Leader and trailer tape specifications The leader has a minimum width of 400 mm which includes at least 100 mm of carrier tape with empty cavities and sealed cover tape (see Figure 2). The leader tape is affixed to the last turn of carrier tape by using a transparent adhesive anti static or paper based tape of a width not higher than the one of the cover tape. The trailer is a carrier tape which minimum width is 160 mm with empty cavities and sealed cover tape, as shown in Figure 2. The trailer tape must be affixed to the reel by using the tape slot of the reel hub. During the unwinding operation, the entire carrier tape must be easily released from the reel hub as the last portion of the tape unwinds from the reel without damaging the carrier tape and the remaining components in the cavities. Figure 2. Leader and trailer tape schematics 6/13 DocID027436 Rev 1 TN1208 3 Labeling Labeling STMicroelectronics “inner box” standard label is placed on each reel at the following locations: • On the box that directly holds the reel • On the damp proof bag if the units are dry packed • On the reel itself The label is attached to the flange that is facing the user when the tape is extracted from the reel at the top right (see Figure 3). Figure 3. Labeling location on reel for carrier tape DocID027436 Rev 1 7/13 12 Device orientation 4 TN1208 Device orientation The largest axis of the component outline is perpendicular to the tape length. The device is positioned in the carrier tape cavity as shown in Figure 4: Device orientation on tape. Pin 1 is located on the top left corner of the package. Figure 4.

The cavity defined by A0, B0 and K0 surrounds the component with sufficient clearance so that: - The component does not protrude above the top surface of the carrier tape. - The component can be removed vertically from the cavity without mechanical restriction, after the top cover tape has been removed. - Rotation of the component is limited to 20° maximum for 12 mm tapes and to 10° maximum for 16 mm and 24mm tapes. - Lateral movements of the component are restricted to 0.5 mm maximum for 12 mm tapes and to 1.0 mm maximum for 16 mm and 24 mm tapes.
