1 Surface Mount Fasteners Revised 98

2 SURFACE MOUNT FASTENERS PEM ReelFast surface mount nuts, spacers, panel fasteners and R ANGLE fasteners are mounted to printed circuit boards in the same manner as other surface mount components prior to the solder reflow process. The fasteners are provided on tape and reel compatible with existing SMT automated installation equipment. Nuts and spacers are available in threaded and unthreaded sizes. Benefits of ReelFast SMT fasteners are: Faster assembly Reduced scrap Reduced handling Reduced risk of board damage that may occur when fasteners are improperly installed with off-line equipment Reduced loose hardware ReelFast SMT fasteners are recommended for reflow soldering designs.
