 | Compact Wave Spring = Big Impact
What will you do with a more compact design? From robotic surgical instruments to bearing preload, Smalley Wave Springs have been the trusted solution in every industry for over 100 years. In applications with tight space constraints, Smalley wave springs are ideal for optimizing space. They offer the same force as an ordinary coil spring, but at up to 50% of the height, leading to an overall decrease in assembly size, weight, and cost.

 | Top 5 reasons for solder joint failure
Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect solder joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes of solder joint failure during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

 | New robust angle sensors for off-highway and more
Novotechnik, U.S. introduces the RFE 3200 Series of resilient, touchless Hall-Effect angle sensors. These sensors are specifically designed to operate in demanding environments like off-highway equipment and feature ingress protection to IP69K, EMC immunity, and a decoupled sensor/magnet. The RFE Series measures from 0 to 360 deg and can be ordered with one (partially redundant) or two (fully redundant) channels. High resolution with great dynamic response, large mechanical tolerances, and feasibility of customer-specific output options are added benefits of this wear-free technology.

 | Posi-Lok keyless shaft bushings for secure shaft-to-hub connection
Zero-Max offers a variety of options within the Posi-Lok keyless shaft bushings (PSL) product line that allow users to rigidly and reliably secure shaft-mounted components into position for optimal operating results in their machines. Options include material choices, plating, and different mounting methods. Posi-Loks are a superior shaft-hub locking solution, eliminating the need for keyways that can weaken or cause excess wear to shaft components. All Posi-Lok models easily slide onto a shaft for mounting and provide reliable, zero-backlash performance.

 | 60 Years Ago: First American in space
In 1961, the United States and the Soviet Union found themselves in a race to put the first human being into space. The Soviets won the race in April 1961, but on May 5, 1961, Alan B. Shepard became the first American in space during a suborbital flight aboard his Mercury capsule named Freedom 7. Three weeks later, President John F. Kennedy committed the United States to achieving a lunar landing before the end of the decade.

Alternative to welded bolts in cars: Adhesive-bonded inserts and clips
A new fastening method called ONSERT technology, developed by DELO and one of its partners, combines bonding and screwing. With ONSERT, fixing elements such as thread inserts or clips are bonded with special light-curing adhesives with extremely short curing times. ONSERTS combine the benefits of welded studs -- such as a high degree of automation, short cycle times, and high load-bearing capacity -- with the possibility of bonding on sheets of less than 0.5-mm thickness as well as on non-metallic lightweight materials. They also add to lightweighting efforts.
