Product Catalog

New Type SMTSOB™ ReelFast® brass fasteners are ideal for applications which demand superior electrical/mechanical attachment points. These fasteners mount on PC boards in the same manner and at the same time as other surface mount components prior to the automated reflow solder process. The fasteners simply become another board component. These fasteners are provided on tape and reel compatible with existing SMT automated installation equipment.

Features and Benefits
  • Better corrosion resistance than steel standoffs
  • Higher conductivity than steel standoffs.
  • Pick-n-place installation provides:
    – Faster assembly
    – Reduced scrap and handling
    – Reduced risk of board damage
  • Reduced loose hardware.
