New PEM® SMTSSS™ ReelFast® SNAP-TOP® standoff fasteners from PennEngineering® hold printed circuit boards securely in assemblies without requiring mating screws or other loose threaded hardware to complete attachment.
These unthreaded standoffs promote streamlined production by easily installing in boards in the same manner and at the same time as other surface mount components prior to the automated reflow solder process. They ultimately enable precise and reliable mounting and spacing of boards using less hardware and fewer operations.
Unlike loose parts with handling issues, PEM SMTSSS standoffs are supplied on tape and reel, compatible with existing SMT automated installation equipment. Without a need for secondary installation operations that may inadvertently be performed improperly, board damage and costly scrap can be avoided.
PEM SMTSSS standoffs are manufactured from carbon steel and are available in unified lengths 0.250 inches or 0.375 inches and metric lengths 6mm, 8mm, or 10mm. They will install reliably in boards and panels as thin as 0.060 inches and 1.53mm.
Detailed specifications, fastener drawings and 3D models, and performance data (Bulletin SMTSS) for these fasteners can be viewed and downloaded for free on the company website.
