How to make PCB spider (holder) for using in projects



If you work with the electronics, the PCB holder is essential item for the best soldering. There are many PCB holder in market, however they are useless or expensive. Getting more easy and accurate soldering is possible by using flexible stand. Copper wire is one of the elastic item and it can be useful in many projects. So using isolated copper wires and crocodile clips as PCB holder allow us to perform more comfortable and perfect soldering.

E Waste Recycling



These films can now be viewed in a higher resolution at http://www.youtube.com/watch?v=Qa6oNloEmgo

The companies Müller Guttenbrunn, Metran and MBA Polymers jointly work on the treatment of E-Waste. This films shows the techniques used to process these e-wastes with the following steps:
1. De-Pollution using a patented smasher, 2. Shreddering in campaigns for only E-Waste, 3. Ferrous metals separations, 4. Non Ferrous Metals separations and these non ferrous metals and printed circuit boards go to smelters and 5. the plastics rich fraction is pre-processed and subsequently recycled into tech plastics that can be re-used in durable products.

Utilizing Circuit Card the nanotech way

PCBs can be pulverised to nanoparticles to recuperate valuable metals, polymers and oxides, affirms latest study.

PCBs are best recycled by pulverizing them into nanosized particles to successfully get back beneficial ingredients such as polymers, oxides and valuable metals, suggest Indian professionals.

The fresh method, detailed in a scientific study publicized in Materials Today in March, is scalable and eco-friendly, mentioned researchers from the Indian Institute of Science (IISc), Bangalore, and the Rice University in Houston, US.

In the scientific study, the researchers adopted the principle that ultra-low temps make materials fragile and are all to easy to pulverise and separate.

They put a PCB in a rotating cylinder with temps brought down to minus 119 degrees Celsius before bombarding it with steel balls to destroy it into nanoparticles which were then spread in H2o.

The nanoparticles could be put to many uses, the researchers said. They could be added to polymer composites strengthening them, employed in 3D printing or in the manufacturing of polymer powder-based paints.

Metallic nanoparticles can be reused after purification by widely known approaches.

“With some original sorting, the method can handle nearly all PCBs, says Kamanio Chattopadhyay, research guide, professor at IISc and an author of the study.

Though the technology is still in the laboratory phase, the research team is now working with an industry to exhibit its scalability and usefulness.

Soldering Wires to External Components & the PCB | Tips & Methods |



This is a video demonstration showing you how to solder wires to external components such as potentiometers or pots (variable resistors), switches, fuse holders, etc. to a printed circuit board (PCB). There will be some suggestions, tips, and methods on how to prevent the wires from falling out of the printed circuit board (PCB) or moving around while soldering. There is a short discussion on wire strippers, and the type of wire to use when assembling a PCB. The tutorial is well suited for the electronic / electrical technician, technologist, engineer, trades person, or home hobbyist that has no experience with electronic proto-typing. This video would be especially useful for the person assembling an electronic kit for the first time. Please watch the additional videos using the DMM, other test equipment, and on soldering techniques.

Handling PCB Board the nanotech way

Circuit Boards can be pulverized to nanoparticles to retrieve valuable metals, polymers and oxides, states new study.

Circuit Boards are best recycled by pulverising them into nanosized particles to successfully retrieve beneficial ingredients similar to polymers, oxides and valuable metals, claim Indian specialists.

The innovative method, described in a study listed in Materials Today in March, is scalable and environment-friendly, explained researchers from the Indian Institute of Science (IISc), Bangalore, and the Rice University in Houston, US.

In the research, the researchers adopted the rule that ultra-low temps make materials fragile and are an easy task to pulverise and separate.

They put a Circuit Board in a rotating cylinder with temps brought down to minus 119 degrees Celsius before crashing it with steel balls to crack it into nanoparticles which were then spread in water.

The nanoparticles could be put to a variety of uses, the researchers said. They could be added to polymer composites improving them, employed in 3D printing or in the manufacturing of polymer powder-based paints.

Metallic nanoparticles can be re-cycled after processing by well-known methods.

“With some early sorting, the method can handle most Circuit Boards, says Kamanio Chattopadhyay, research guide, professor at IISc and an author of the study.

Even if the technology is still in the laboratory phase, the research team now is working with an industry to demonstrate its scalability and usefulness.
