Heavy metals such as mercury and lead have a negative effect on humans and can damage their nervous system. Also, these metals affect the reproductive system, and kidney. Consumption of lead via contaminated water will minimize the functioning of body organs like ankles and fingers. As more ...
“We humans have to decide what to do with the knowledge that we are a little bit plastic inside,” says Heather Leslie, an independent scientist who pioneered microplastics and human health research in Europe. While the extent of the potential damage is still unexplored territory, Leslie tells...
You can also speed up the whole SMT assembly process. Companies can produce multiple batches of PCBs using this automated technology. Machines also don't get tired and always keep working at full throttle. You can also forget about mistakes and misplacements that happen with humans. Engineers ca...
The following tools aren't necessary, but they sure do make soldering easier at times. Third Hand (Third Arm) Third Hand (Third Arm) - Third hands are great for holding PCBs, wires, and components in place while you solder. The articulation depends on how the third arm is manufactured. ...
Day to day the land becomes further polluted by humans. The well-being of the environment is threatened by these pollutants. These pollutants include DDTs, PCBs, and organophosphate pesticides. DDT was once thought of as a very effective chemical. It was… ...
Plastic has become indispensable for human life. When plastic debris is discarded into waterways, these items can interact with organisms. Of particular concern are microscopic plastic particles (microplastics) which are subject to ingestion by several t
the hundreds of tons of DDT and PCBs, another toxic chemical, that had been released two miles off the coast of Palos Verdes where the sewage emptied into the ocean. Many saw the need to make this public health problem — much closer to shore, with visible harm to humans and the ecosyst...
Making PCBs isn’t my schtick, but the appears to be a pretty standard Pick-and-Place machine. Every time I’ve seen one of these running, I am shocked at how fast they are.The hand assembly of the Mac Pro uses an under-table parts delivery system. I had never seen this before ...
“Millions of people who take fish oil for health benefits have been kept in the dark about the levels of PCBs and other contaminants they may be swallowing with the omega-3s.” “Somesupplementscontain labels that say ‘treated to remove contaminants,’ but those labels do not tell consumers...
WARNING:When you are testing high frequency drivers (tweeters or such) do not apply them to a low frequency source. Never! It will damage the driver. For example, they will not survive 500 Hz at a high power. . Use your phones application “frequency sound generator” (pick whichever you...
