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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
