Global designer and manufacturer of thin sheet fastening devices and installation systems, PennEngineering, has introduced new PEM SMTSSS ReelFast SNAP-TOP standoff fasteners. The fasteners hold printed circuit boards securely in assemblies without requiring mating screws or other loose threaded hardware to complete attachment. These unthreaded standoffs promote streamlined production by easily installing in boards in the same manner and at the same time as other surface mount components prior to the automated reflow solder process.
They ultimately enable precise and reliable mounting and spacing of boards using less hardware and fewer operations.
Unlike loose parts with handling issues, PEM SMTSSS standoffs are supplied on tape and reel compatible with existing SMT automated installation equipment. Without a need for secondary installation operations that may inadvertently be performed improperly, board damage and costly scrap can be avoided.
PEM SMTSSS standoffs are manufactured from carbon steel and are available in unified lengths 0.250 or 0.375” and metric lengths 6, 8, or 10mm. They will install reliably in boards and panels as thin as 0.060” and 1.53mm.
