New Brass SMTSOB

Brass Reelfast fasteners from PEM offer superior electrical conductivity and corrosion resistance

SMTSOBF Fasteners
New PEM® ReelFast® brass surface mount fasteners from PennEngineering® introduce ideal hardware solutions for printed circuit board applications requiring superior electrical and mechanical attachment points. These tin-plated Type SMTSOB brass nuts and spacers/standoffs install permanently on printed circuit boards in the same manner and at the same time as other surface mount components prior to the automated reflow solder process. They can serve reliably to space or stack boards, mount boards, and/or attach components.

SMTSOB fasteners ultimately exhibit greater corrosion resistance and higher conductivity than steel counterparts and their pick-and-place installation delivers key efficiencies and economies. Among the benefits, the fasteners can reduce the risk of damage to boards (and resulting scrap) typically resulting when conventional fasteners are improperly installed with off-line equipment, minimize the number of loose parts and related handling issues, and promote quicker assembly by eliminating secondary operations during the installation process.

Threaded versions are available in sizes M2 through M4 and thruough-hole (non-threaded) types can be specified in sizes 3.6mm, and 4.2mm. Lengths range from 2mm to 10mm. All are designed for use with boards of any hardness and as little as 1.53mm thick. A full range of unified sizes are also available.

The fasteners are supplied on tape and reel conforming to industry standards and compatible with existing SMT automated installation equipment. A polyimide patch affixed to the end of the fastener allows for vacuum pickup.
