The new PEM SMTSK unthreaded standoffs from PennEngineering permanently surface mount on PCBs to enable quick attachment and removal of stacked components without requiring screws or tools. Their unique barrel design allows for a stacked board or panel to be slipped easily into place and then detached by simply sliding the component sideways and lifting it off. These standoffs will effectively serve to attach and space components either horizontally or vertically using minimal hardware and fewer assembly operations.
Supplied on tape and reel compatible with existing SMT automated installation equipment, the standoffs will mount on PCBs in the same manner and at the same time as other surface mount components prior to the automated reflow solder process. These hardware solutions ultimately can reduce handling issues, risks of board damage, and costly scrap, while promoting streamlined production and “screwless” designs of subassemblies.
