SMTSSS-4MM-6 ET
SMTSS™ REELFAST® Surface Mount SNAP-TOP® Standoffs
PEM® surface mounted standoffs that eliminate the need for attaching screws
- PEM® SMTSS™ fasteners feature a spring action to hold a P.C. Board securely without screw or threaded hardware, allowing for quick assembly.
- Mount on P.C. Boards in the same manner and at the same time as other surface mount components prior to the automated reflow solder process.
- Alleviated concerns about potential damage to P.C. Boards due to improper secondary installation operations.
- Fasteners provided on tape and reel compatible with existing SMT automated installation equipment.
- Benefits include reduced scrap, reduced handling and reduced risk of board damage.
