Do you suffer from headaches, blurred vision or eye strain? You could have computer vision syndrome (CVS). CVS affects about 90 percent of people who spend three hours or more a day at a computer.
One of the biggest culprits? Inadequate lighting. Improper lighting exacerbates the problem and also reduces productivity, and yet the amount of light in the workplace remains one of the most common complaints. Specifically, ambient lighting is frequently too high and task lighting too low. Glare from computer screens and light sources also leads to unwanted aches and pains.
With ergonomic lighting, the problems associated with CVS are typically alleviated, and operational efficiencies improve. Proper and adjustable task lighting at every workspace is necessary to mitigate the symptoms of CVS.
Your lighting needs will vary by task and by your age; reading, for example, requires more light than computer work, and a 60-year-old needs more light than a 20-year-old. Task lights with adjustable arms and dimming controls provide maximum flexibility. When your workspace is properly lit, the entire space should be illuminated, and glare should be minimized.
Improve well-being, productivity and job satisfaction with All-Spec’s selection of ergonomic task lighting for every task, and combat the serious effects of CVS in the workplace.
The wrong soldering tip can quickly turn a routine task into a train wreck. With so many different types of tips on the market, it’s easy to get derailed. The best tip is to know which tip is the best tool for your specific task before you begin. Here are four of the more common ones, so you can always stay on track:
Chisel Tip: Perhaps the most common of soldering tips, the chisel tip is easy to use and serves multiple purposes. This is a good tip type for beginners. It’s ideally suited for creating smooth joints and smoothing over solder deposits.
Pointed Tip: Need to do small, detail work? Reach for the pointed tip. It’s great for moving solder around once it’s been deposited. Use it to create small solders and pinpoint where you want your solder material to land. Beginning and advanced users rely on the pointed tip.
Rounded Tip: The rounded tip offers stability in soldering and is used for depositing solder and for creating strong joints. It’s a solid choice for both beginners and advanced users.
Mini Wave Hollow Tip: The hollow tip features a small well that holds solder material at the tip. This makes it easy for depositing. Beginning and advanced users choose the hollow tip to move solder around while it’s still hot.

A new type of LED could lead to cheaper, brighter lights as well as mass produced displays thanks to a team of Florida State University materials researchers. The organic-inorganic LED hybrid is made of a class of materials called organometal halide perovskites. Perovskites have the same type of crystal structure as calcium titanium oxide.
After months of experiments using synthetic chemistry to make the class of material perform better than initial tests suggested, researchers were surprised to discover the material glowed exceptionally bright. It measured at about 10,000 candelas per square meter or about 25 times brighter than a computer screen and displayed remarkable stability.
The findings, published in Advanced Materials, are advantageous for industry as the earth abundant material can be processed in an economic way, which until now has been one of the major obstacles to LED advancement despite their heralded energy-savings.
Switching solder paste when you’re getting the yields you want may sound like throwing out the solder paste with the circuit board, but listen again. Advances in paste technology necessitate continual evaluation. Whether you need to tackle lead-free, head-and-pillow or another reflow issue, the surge in materials coming to market warrants an intermittent process to evaluate and qualify these new solder pastes.
But, what is an appropriate level of testing considering time and budgetary constraints? World-class suppliers perform rigorous laboratory testing. These tests, performed by reputable organizations, are solid. Is there any merit in replicating them? Generally speaking, no.
Today, it’s more commonly accepted to buy into the test results that are done by the paste manufacturer lab. However, you may want to consider conducting your own performance tests or process tests. These are tests that evaluate how each new paste performs during your specific process. They make look at printability, shelf life, tack and more.
Then, consider doing a design of experiments (DOE) such as the 27-board challenge developed by Cookson Electronics. It’s an economical and practical test that examines several parameters with a small sample size.
Keeping apprised of new developments in technology helps to ensure you are always operating at peak performance, so making any number of switches will always sound like music to your ears.
Did you know you spend more than 90 percent of your time indoors where you’re exposed to pollution levels up to 1,000 times higher than those outdoors? Products that release volatile organic compounds (VOCs) contribute to allergies, asthma, reproductive problems and cancer. And, the ensuing economic impact on employee health and productivity is estimated to be “tens of billions of dollars per year,” according to the EPA.
Bevco understands the importance of creating products that do not contribute to poor indoor air quality. The prominent manufacturer of ergonomic seating solutions recently achieved the UL’s GREENGUARD Gold Certification for select seating products. The third-party certification program requires products to undergo testing for thousands of VOCs; only those meeting the UL’s stringent chemical emission limits achieve GREENGUARD Gold Certification.
In addition to limiting emissions of over 360 VOCs and total chemical emissions, GREENGUARD Gold Certified products must also comply with requirements of the State of California’s Department of Public Health. All-Spec carries a number of GREENGUARD certified chairs from Bevco, so you too can reach for the gold when you reach for the green.
