Printed Circuit Board (pcb)
Electrical circuit created by laying (printing)
a�tracksa�? of a conductor such as copper on one or both sides of an insulating
board. The Printed circuit board was invented in 1936 by Austrian scientist Paul
Eisler, and was first used on a large scale in 1948 China PCB Prototype.
A PCB is
the acronym for Printed Circuit Boards, which are cards or circuit boards that
are composed of a very thin flat metal or hard plastic-type board called an
insulator. It is upon this that computer silicon chips and other similar
electronic components are mounted. These boards are then used in electronic
appliances like televisions, computers, washing machines, digital cameras, and
so forth.
Components such as integrated circuits (chips), resistors, and
capacitors can be soldered to the surface of the board (surface-mounted) or,
more commonly, attached by inserting their connecting pins or wires into holes
drilled in the board. The increased component density and complexity required by
the electronics industry demands increasing use of multilayer PCBs which may
have three, four, or more intermediate layers of copper conductor. PCBs include
motherboards, expansion boards, and adaptors.
A PCB prototype is the
first circuit board that is invented for a new electronic device. By using this
prototype in the electronic device, the inventor can see if the prototype serves
its purpose in the invention. Once the electronic device is made to function
with the prototype, any mistakes that take place can be rectified in the
prototype Rigid flex PCB. In this
way, the PCB prototype saves the inventor of the electronic appliance lots of
money, as any mistakes that may be present in the PCB will be pinpointed before
the actual commercial manufacture of the PCB.
Without having a prototype,
the model of a new invention will be of no use if its board is not in good
condition and up to requirements. Electronic appliances are getting more and
more technologically advanced by the day. This advancement is done through
changes on a prototype, which is then tried on the appliance to see if the
advancement is in right order. Using different materials of the boards also
account for changes in the prototype. You can use fiberglass, Teflon or
cross-linked polystyrene for the PCB, and it is through the prototype that you
find out which material best fits your needs. Nowadays, new PCBs are in use in
electronic appliances, thanks to the prototypes.
