PEM® Reelfast® SMT Spacers/Nuts for PC Boards Now Available in More Thread Sizes
Threaded PEM® ReelFast® SMT spacers/nuts are available in more thread sizes to satisfy the widest range of application requirements. These fasteners are ideally suited to space or stack printed circuit boards or (as nuts) to mount boards or attach components. They install on PC boards in the same manner and at the same time as other surface mount components prior to the automated reflow solder process and simply become another board component.
Among their production and cost advantages, ReelFast SMT spacers/nuts reduce the risk of damage to boards (and resulting scrap) that may occur when improperly installing fasteners with off-line equipment; reduce handling of loose parts to deliver labor savings; and speed assembly by eliminating secondary operations.
Threaded types are offered in sizes #2-56 through #8-32 and M2 through M4 and thru-hole (non-threaded) types in sizes .116", .143", 3.6mm, and 4.2mm. Lengths range from .065" to .375" and 2mm to 10mm.
All types can be installed in boards as thin as .060"/1.53 and all are RoHS compliant.
Tape-and-reel packaging for their automated installation conforms with industry standards and preferences for other surface mount components. Each reel carries up to 1,500 parts, depending on fastener size. Fasteners are supplied with Kapton® patch for vacuum pickup.
