Steel Fasteners can be used as nuts or standoffs in SMTapplications.
Press Release Summary:
Featuring hex-shaped barrel, ReelFast® microPEM(TM) Type SMTSO(TM) Fasteners install permanently on PCBs in same manner and at same time as other surface mount components prior to automated reflow solder process. Fasteners come in thread sizes as small as No. 0-80 with lengths as short as 0.62 in., and all can be installed in boards as thin as .020 in. Packaged on 13 in. recyclable reels, fasteners can serve as nuts or standoffs to space or stack PCBs, mount boards, or attach components.
Original Press Release:
ReelFast® MicroPEM(TM) Fasteners for Nut/Standoff Applications
INSTALL ON P.C. BOARDS WITH OTHER SURFACE MOUNT COMPONENTS
New ReelFast® microPEM(TM) (Type SMTSO(TM)) fasteners for compact electronic assemblies install permanently 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. A unique hex-shaped barrel provides a larger solder area and, upon installation, the steel fasteners become another board component. The fasteners can serve equally well as nuts or standoffs to space or stack P.C. boards, mount boards, or attach components.
Their use can reduce the risk of damage to boards (and resulting scrap) that may occur when conventional fasteners are improperly installed with off-line equipment, minimize the number of loose parts, reduce board handling, and promote quicker assembly by eliminating secondary operations.
The fasteners are offered in thread sizes as small as M1 / #0-80 and lengths as short as 1mm / 0.62". All can be installed in boards as thin as 0.5mm / .020".
Fasteners are packaged on 13" recyclable reels measuring 16mm in width. Reels conform to EIA-481 standards and are compatible with existing SMT automated installation equipment. A supplied polyimide patch for the end of the fastener allows for vacuum pickup.
Detailed specifications (Bulletin MSMT) and free part drawings (PEM CAD Library) for these RoHS-compliant fasteners can be accessed at www.pemnet.com
These fasteners join a growing family of microPEM fasteners and capabilities. All microPEM products are manufactured by PennEngineering®, founded in 1942 and this year celebrating 70 years of excellence and innovation in fastening technology.
