How can I meet the sales of electronic components to do a friend!
I hope we can help each other.
Regards
Hi, you can connect with suppliers through http://www.globalsources.com/
They have suppliers from all over the world whom can provide you with goods at wholesale rates.
You can also try posting at craigslist.org under one of the business categories seeking electronic suppliers.
I have a large quantity of surplus electronic components such as transistors, diodes, connectors etc. These are all probably between 3 and 15 years old with a few parts a bit older. Most of the parts are radio frequency stuff.
Where is a good place to sell this stuff?
How about Ebay? You might need to catalog and package.
[Keio Spintronics Network - Tada Laboratory , Osaka University]
The Tada Laboratory at Osaka University is working to fabricate electronic components, such as transistors and diodes, from organic substances.
Most organic materials dont conduct electricity. But its become clear that, by carefully designing molecular structures, electronic components like those made from silicon can also be made from organic materials.
Q. Currently, silicon transistors are the norm. But were studying how to utilize the flexibility and constituents of organic materials in electronic components. The human brain is also made of organic materials, so we hope that in the future, itll be possible to simulate the brain.
The electronic components that support everyday life are rapidly becoming smaller. If this process is taken to its ultimate limit, to make components from single molecules, then the most attractive materials are organic molecules, which can be freely formed with various shapes.
Q. Organic materials are very diverse. Because they have such individuality, were trying to make transistors by combining them skillfully. Current silicon transistors take a huge amount of energy to manufacture, but organic components can be made by a very simple process, like printing postcards. So it seems that very cheap, environmentally friendly components could be made very easily. We think they may serve as one means of supporting a new ubiquitous society.
One aspect of the Tada Labs research concerns the fundamental question of how to connect single molecules to electrodes to pass a current. The properties of molecules connected to electrodes are affected by the electrodes. The Lab uses a scanning tunneling microscope to actually observe single molecules on electrodes, and see how the properties of the molecules change. Also, electrodes are attached to single-molecule terminals, to actually measure the resistance of the molecules and reveal the principles by which the current flows.
Another aspect of the Labs research is investigating the functions of organic materials. The researchers make transistors by attaching electrodes to films of organic materials, ranging in thickness from one molecule to tens of nanometers. They then study new functions, such as luminescence created by manipulating the carriers in the films. The Lab is also investigating whether organic films can transmit not only currents, but also a property called spin, which has an electric charge.
Q. Devices like mobile phones are becoming smaller and smaller, but if such devices could utilize flexibility, for example, they could be built into clothing, or used to make flexible displays and computers that can be rolled up.

I wanted to know how electronic components can be miniaturised.
integrated circuits have come a long way in the last 30 years. For example, your computer has (at least) several tens of thousands of times the memory of the original space shuttle. This has been accomplished by improving the processes with which we make semiconductor chips. By linking many transistors (electronic switches) together in very small spaces, we end up with powerful devices with the ability to store a lot of data (in 0’s and 1’s that can be represented by the transistors) and lots or processing power (small circuits to act upon those binary digits). I’ve included some links to wikipedia articles that might help you learn more.

I know what "surface mounting" is, but thats about it. If I buy electronic components online, what kind of mounting should they be if I want them to have leads?
Through hole mounting. If they have leads you will have to solder them on using a soldering iron.
