The Airglide LED Wafer
System from Dover
is now available in a wide base version for additional stiffness and support
for larger payloads up to 50kg, over travels up to 1 m. The Airglide
system is a maintenance-free positioning solution for stepping or scanning
applications, and for laser processing of LED or semiconductor wafers. Other
applications include metrology or precision imaging systems which require high
accuracy step positioning moves.
The Airglide system has straightness to ±0.5 µm, compensated
accuracy to <1 µm, and bi-directional repeatability to ±0.4 µm. Depending
upon the payload, it can accelerate at 5 m/s2, provide maximum velocity of 1000 mm/s and deliver
continuous force of 76 N and peak force of 240 N over available travel ranges
from 100 to 1,000mm. The system can be operated with servo drive control
hardware, or packaged with a Dover control solution.
Available options include motion rotary and z-theta
products, granite base, and granite bridge, which can be integrated with the
Airglide XY. When configured in a vertical orientation for use as a Z
axis, a pneumatic counterbalance system can be provided. Customized
pneumatic tubing and signal cabling is also available for customer-enabling
technology or additional axes.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
