Surface Mount Device (SMD) Tape and Reel Information

Surface-Mount Products Description

Maxim is committed to providing high-quality high-reliability surface-mount products. Nearly every product is offered in a surface-mount package. Surface-mount products are tested through the same production flow as dual-in-line (DIP) plastic devices and are tested to the same stringent electrical and visual AQL levels. Product qualification and reliability monitoring programs for DIP and surface-mount products are nearly identical. Surface-mount products are additionally subjected to preconditioning prior to many reliability tests. Refer to our product reliability report for details.

Surface-Mount Packages in Reeled Tape

Maxim surface-mount packages are shipped in antistatic plastic rails. For customers using automatic placement systems, parts also come mounted in pockets on embossed tape. The tape is wound and shipped on reels. The table and diagram on this page indicate the tape sizes used for various package types and the basic orientation convention used. Further tape-and-reel specifications can be found in the Electronic Industries Association (EIA) Standard 481.
