Part Details:

AN577 APPLICATION NOTE PACKAGING AND SOLDERING METHOD DEVICES IN SMA, SMB AND SMC PACKAGE PACKING Devices in SMA, SMB and SMC package are delivered in standard embossed 12 & 16 mm tape and reel(EIA 481A standards). This packing minimizes handling and is fully compatible with state-of-the-art assembly technology for hy-brid circuits and printed circuit boards. The diodes are pre-orientated and the tape can be used directly on automatic pick and place equipment. Picking up is easy thanks to the rectangular parallelepiped shape. For this, the use of a vacuum chuck isvery efficient due to the flatness of the upper side of the components, thus avoiding air leakage. Figure 1. Epoxy encapsulationcompound Terminal Table 1.
