Seifert thermoelectric coolers from AutomationDirect

Automation-Direct has added new high-quality and efficient stainless steel Seifert 340 BTU/H thermoelectric coolers with 120-V and 230-V power options. Thermoelectric coolers from Seifert use the Peltier Effect to create a temperature difference between the internal and ambient heat sinks, making internal air cooler while dissipating heat into the external environment. Fans assist the convective heat transfer from the heat sinks, which are optimized for maximum flow.

What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

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 joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

Strongest first quarter on record: North American robotics market surges 32% in unit volume

North American robotics companies posted the strongest ever first-quarter results, according to the Robotic Industries Association (RIA), the industry's trade group. Both robot orders and shipments achieved record levels.

An all-time high total of 9,773 robots valued at approximately $516 million were ordered from North American robotics companies during the first quarter of 2017. This represents growth of 32 percent in units over the same period in 2016, which held the previous record. Order revenue grew 28 percent over the first quarter of last year. Robot shipments also reached new heights, with 8,824 robots valued at $494 million shipped to North American customers in the opening quarter of the year. This represents growth of 24 percent in units and 5 percent in dollars over the same period in 2016.

"The automation industry continues to grow robustly as companies invest to increase productivity and boost competitiveness while also providing opportunities for workers," said Jeff Burnstein, president of RIA. "We are excited to hear about the new jobs being created and how companies such as Amazon, GM, and others are training and retraining their workforce to enable them to embrace these higher skilled jobs."

Growth in automotive soars
Growth in automotive-related industries soared in the first quarter of 2017. Robots ordered by automotive component suppliers were up 53 percent, while orders by automotive OEMs increased 32 percent. Another good sign for the future of robotics was the continued growth in non-automotive industries like metals (54 percent), semiconductors/electronics (22 percent), and food and consumer goods (15 percent).

The biggest increases were in arc welding (102 percent), coating and dispensing (64 percent), and spot welding (36 percent) applications. RIA estimates that 250,000 robots are now in use in the United States, the third highest in the world behind Japan and China.

Attendance at Automate show up
RIA and its parent group, the Association for Advancing Automation (A3), see the impact of the growth in demand for robotics and related automation at industry events such as Automate 2017, recently held in Chicago April 3-6. This year's show featured more than 400 exhibitors displaying their latest technologies and services, including global suppliers of robotics, motion control, motors, vision systems, metrology, software, and system integration services for enterprises large and small. Over 20,000 people attended Automate 2017, including over 1,000 participants in the 120+ Automate conference sessions held at the event.

"All of our statistics increased significantly from the last Automate show in 2015," added Burnstein. "Total number of show attendees jumped 37 percent, and conference participation grew by over 90 percent compared to 2015."
