PennEngineering's new PEM® micro self-clinching standoff
fasteners can serve as practical, cost-effective, and permanently secure
solutions enabling quicker assembly of devices ranging from hand-held consumer
electronics to medical equipment, among others.
PEM Type MSO4™ micro
self-clinching standoffs are manufactured from 400 Series stainless steel and
are engineered with threads as small as M1.0 / #00 and in lengths as short as 2
mm / .080 inch. They can be installed into sheet metal (including 300 Series
stainless steel) as thin as 0.4 mm / .016 inch with maximum hardness up to HRB
88 on the Rockwell "B" scale.
The micro standoffs clinch permanently
into place by pressing them into a properly sized mounting hole using a punch
and anvil until the fastener's head is flush with the sheet. Upon installation,
they become a permanent part of an assembly, will not loosen or fall out, and
provide strong and reusable load-bearing threads. Installing them automatically
can further reduce costs by accelerating production and eliminating any need to
handle the small parts.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
