When comparing them to breadboards and stripboards:
Advantages - it is a permanent method of producing a circuit
- they are custom made so can be very small
- they can be mass produced and so economical
Disadvantages - can't be modified once printed (has to be completely re-designed)
- can't change components

How do you make a circuit without wires?
Using tracks of metal such as on a PCB (printed circuit board) or using other electrically conductive material such as the graphite in 'lead' pencils.
How are printed circuit boards manufactured?
Printed circuit board are electronic circuits created by mounting electronic components on anonconductive board, and creating conductive connections between them. The creation ofcircuit patterns is accomplished using both additive and subtractive methods. The conductivecircuit is generally copper, although aluminum, nickel, chrome, and other metals are sometimesused. There are three basic varieties of printed circuit boards: single-sided, double-sided, andmulti-layered. The spatial and density requirement, and the circuitry complexity determine thetype of board produced. Printed circuit boards are employed in the manufacturing of businessmachines and computers, as well as communication, control, and home entertainment equip-ment.
What are circuit board connectors used for?
A circuit board connector is used to mechanically support and connect electronically the various components of a circuit board. It does this using conductive pathways and signal traces.
What are the disadvantages of using ammeter and voltmeter?
The disadvantage of using a voltmeter and ammeter on circuit measurements is that internal burden in both these instruments can affect circuit operation so much as to make a measurement useless.
Should solder be reheated on a circuit board?
Yes, once or twice using flux but only with prototype boards.

What is PHB that come in mobile?
You perhaps meaning PCB which means a printed circuit board. Solder is printed onto a specifically designed fiberglass board which electronic components can the be soldered onto (attached using liquid metal)
What is a printed circuit board?
A printed circuit board is basically used to mechanically support while at the same time electrically connecting electronic components by using conductive pathways. The process is very simple.motherboard is a printed circuit ,where all components of the system is connected.Printed circuit boards are used in nearly all electronic devices.The conducting wires that connect all the components, are printed onto an insulating plastic material such as paxolin or fiberglass. These tracks are commonly made of thin copper sheet stuck to the board. The tracks are then printed using light and a chemical process to remove the unwanted copper.Some boards used in remote controls and wafer thin boards used in ipods etc, are commonly printed, using conductive ink containing silver or carbon.The alternative to printed circuits was to idividually wire the coponents using wire and solder tags. Old tube radios were originally wired this way, but had to be made by hand.Printed circuits allow for automation and mass soldering using a float soldering process on a bed of molten solder.

What is the disadvantage of using a voltage doubler?
The primary disadvantage of this circuit is that stray capacitances are much more significant than with the Dickson multiplier and account for the larger part of the losses in this circuit

What does SMT mean when talking about electronic circuits?
SMT stands for Surface Mount Technology. It's a way to make a circuit board by placing the parts directly on the circuit board. The board is pre-printed to show exactly where to mount the parts, kind of like a child's puzzle where underneath each piece is a picture of the piece that should go over top of it. SMT has mostly replaced Through-hole Technology, which was where the parts attached to the circuit board using wire leads that would fit through holes in the circuit board.
How do you test electronic circuit board components?
By using a multimeter
What is disadvantage of using robots?
They must be given an ordered set of tasks within the capabilities of their programming. In electronic circuit board assembly they must be given the correct parts in the right place otherwise they are prone to making scrap circuit boards at a very high speed.
If using the brakes lights up the front turn signals do you suspect a bad ground?
no... I would suspect a MAJOR mis-wiring. depending on the vehicle, it could be something in the ECU or printed circuit board.
What is a disadvantage of used fuses?
One disadvantage of using fuses is when you have a short circuit condition and the circuit opens, the fuse has to be physically removed and replaced with a new one. This is unlike a breaker that just has to be reset to the on position.
Full form of PCB?
In electronics, printed circuit boards, or PCBs, are 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 or PWB or etched wiring board. After populating the board with electronic components, a printed circuit assembly (PCA) is formed. 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, faster, and consistent in high volume production. In chemistry and environmental protection, PCB stands for "polychlorinated biphenyl." This class of chemical was widely used as electrical transformers because it will not burn. It was also used as a plasticiser in caulks and palstic materials. Only very limited uses of PSBs are now permitted in the United States and areas that have been contaminated with PCBs through leaks or less stringent disposal practices of the past oftenrequire extensive cleanup.
