DFM Your Device? Simulation Is the Answer

Design for Manufacturing (DFM) has taken off like a rocket in the electronics industry in recent years. Performing process and device simulations on CMOS transistors in a DFM flow have proven to be important in shortening the design cycle and reducing the production cost by improving yield. These are the key elements to why DFM mans the gate to the success of semiconductor foundries and companies.

HBLEDs: Tackle Your Silicone Packaging Problems

It is widely known that the light emitting diode (LED) R&D and commercialization community is striving to produce higher power, bright-white-light LEDs. From both a temperature and UV-resistance standpoint, silicone is rapidly becoming the material of choice for the next-generation chip encapsulant. But as LED manufacturers look to employ silicones in their manufacturing processes, they must be aware of potential problems. Cure inhibition can lead to unacceptable variations in the manufacturing process and thus, the finished product. This article takes a brief look at the benefits of using silicones in high-brightness LED (HBLED) applications, with a focus on potential production floor issues and their solutions.

Adaptive Algorithms, Multi-Cores, and Networks Mark New Machine Vision Era

Potato chips, cell phones, razors, and baby diapers are just a few of the many everyday items made with the help of industrial machine vision. In fact, any product that is manufactured in either high volume, high accuracy, low cost, or a combination of all three can be made better, faster, and less expensively using machine vision.

Infrared Vision: SWIR Sees the Furnace Through the Flames

The ability to make thermal measurements and image through materials that confound more expensive thermal cameras is pushing shortwave infrared (SWIR) sensors into a growing number of industrial process monitoring and thermography applications, typically those of 100 °C or more.

Medical Imaging: Multimodal Techniques Find Life’s Answers

Traditional research on disease mechanisms in animal models mainly has relied either on the detection of morphological changes of the diseased tissues obtained through anatomical imaging, or on the excision and pathological study of the tissues of interest. These methods often require long time periods for measurable changes to occur and large numbers of test animals because multiple animals are often sacrificed at each experimental point for histological testing.

Middleware Bridges the Optical/Mechanical Design Gap

Mechanical CAD (computer-aided design) programs have become very sophisticated during the past few years. Unfortunately, there is still a portion of the engineering spectrum that cannot be handled well in a traditional CAD program: optical modeling. If you are creating a complicated optical system (think of a camera zoom lens), then it is best to perform almost all of the design in a specialized optical design software program and then transfer the optical design to a CAD program for the later stages of the design process where items like housings, threads, cams, and motors are designed and integrated into the model.
