i want to learn something about PCB,Please help meThank you
Good answers, above. Don't do stunts on public roads. Start out with about a 300-400cc machine, depending on your body weight. I'm 160lbs and a 500cc machine is a rocket. If your bike is too small, like 125cc, there's not enough oomph to get you out of trouble. Too big, and it's plain unmanageable. Be safe, and watch for those cell-phone idiots.
Getting on to wheelying (on demand or by mistake) is quite a short trip, shortly after that you learn how to ride a motorcycle, if you haven't taken a short trip to casualty in the meantime. Doing wheelies is not difficult, it is not big, it is not clever. Just as any idiot can ride a bike fast in a straight line, any idiot can get a wheelie out of a bike To avoid motorcycle accidents you need to avoid trying to do stunts – it is not certain you will have an accident, trying out stunts on a public road will make it more likely. To reduce the chances of having an accident, get some proper tuition, take it easy, learn the benefits of observation, develop your anticipation of the behaviour of other road users (this takes time and you can never predict every move). To save on fuel – look at a smaller (displacement) machine, also good for learning on, ride using the plateau of the torque curve, avoid hard acceleration, use your observation to avoid having to brake hard.
PCB is a kind of electronic products, which could assembly many kinds of electronic products, and make of the whole products.
A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, or traces, etched from copper sheets laminated onto a non-conductive substrate. Alternative names are printed wiring board (PWB),and etched wiring board. A PCB populated with electronic components is a printed circuit assembly (PCA), also known as a printed circuit board assembly (PCBA). PCBs are rugged, inexpensive, and can be highly reliable. They require much more layout effort and higher initial cost than either wire-wrapped or point-to-point constructed circuits, but are much cheaper and faster for high-volume production. Much of the electronics industry's PCB design, assembly, and quality control needs are set by standards that are published by the IPC organization.
