    hello,friend;..



    :: You want definition of the PCB ,you don't worry see bellow definition of the PCB read carefully;...

    Printed Circuit Board :PCB

    :: This is thin board that electronic components are placed,which side made from copper, this layer is conductive traces to connecting foots of electronic components. The layer can be more than 1 side copper coated, as i know maximum are 12 layers.

    :: And this is a non-conductive material. And this used material is fiberglass, epoxy and copper.

    :: The thickness of the circuit board is 35 micrometers and 17-18 micrometers.

    PCB may refer to:

    Science and technology:
    • Printed circuit board, and board used in electronics
    • PCB (software), software to design printed circuit boards
    • PCBoard, bulletin board software for MS-DOS
    • Polychlorinated biphenyls, organic compounds
    • Power circuit breaker, an automatically operated electrical switch
    • Process control block, a data structure in software
    • PCB Piezotronics, a manufacturer of piezoelectric sensors
    Government uses :
    • Brazilian Communist Party, Partido Comunista Brasileiro
    • Communist Party of Bolivia, Partido Comunista de Bolivia
    • Police Complaints Board, in England and Wales
    Other uses:
    • Pakistan Cricket Board, regulatory board for cricket in Pakistan
    • Panama City Beach, Florida
    • Prifysgol Cymru, Bangor, a university in Wales
    • Perfect Cherry Blossom, a computer game
    • Phelps County Bank, a bank in Missouri, United States
    NOTE:PCB can be found in almost electronic device, like radio, cellular phone, TV, etc.

    Re: What is PCB?

    Dear friend
    PCB stands for Printed circuit board
    PCB are mainly 2 types
    1.Dot PCB
    2.Line PCB
    PCBs are used to place electronic components in circuit by soldering.PCB are essential part of electronic devices

    Re: What is PCB?

    Dear friend,
    MY friend PCB is a combination of subjects physics,chemistry,biology.All these three subjects comes under science stream.

    IN science stream physics and chemistry is mandatory and yo can choose one out of maths and science or can have both and one language subjects is mandatory also.

    Now after doing 12th in science side there are a lot of options you can do.

    If you have studied PCB(physics,chemistry,biology) in 11th-12th class then you can go specially in medical field.

    Like you can become a doctor,a dentist,veteran.For all these you have to appear for entrance exams.

    Actually different colleges arrange their own entrance test but most of them give admission through CBSE PMT exam.

    Pattern for the exam:

    1.In CBSE PMT there are two exams first is pre test in which objective questions are asked .there are three sections physics,chemistry,biology.Only conceptual questions are asked.
    after that if you clear that exam then you have to appear for main exam which also consists three sections but questions will be subjective type.

    2.In other exams like AFMC,AIIMS questions are asked from all three subject(PCB).

    3.If you take coaching for MBBS that will be very helpful to your preparation,you will get the idea about which type of questions are asked.
    Other than CBSE-PMT you can appear for different exams through which you will get admission in good MBBS college.

    AIIMS - All India Institute of Medical Sciences AIIMS Entrance Exam

    AFMC - Armed Forces Medical College Exam AFMC Entrance Exam

    AIPMT - All India Pre-Medical / Pre-Dental Entrance Examination AIPMT Exam...

    MP DMAT - All India Dental & Medical Admission Test - Madhya Pradesh MP DMAT Medical Entrance Exam

    AIMS - Amrita Institute of Medical Sciences Aims Medical Exam

    AIPGMEE - All India Post Graduate Medical/Dental Entrance Exam AIPGMEE

    AU AIMEE - Annamalai University-All India Medical Entrance Examinations AU AIMEE

    Bharati Vidyapeeth University Medical Entrance Exam Bharati Vidyapeeth University

    Some of best MBBS college in India is follows:
    1. AIIMS, Delhi
    2. Armed Forces Medical College, Pune
    3. Christian Medical College, Vellore
    4. JIPMER, Puducherry
    5. Kasturba Medical College, Manipal
    6. Lady Hardinge Medical College, Delhi
    7. Maulana Azad Medical College, Delhi
    8. Grant Medical College, Mumbai
    9. St. Johnís Medical College, Bangalore
    10. Madras Medical College, Chennai

    Some of the above colleges colleges also offer dentist course.

    Apart from doctor you can apply for biotechnology course which is very favorite now.Its 4 yrs course,you have to appear for entrance exam for this.

    But if you have studied maths also then you can apply for engg. course.You can also go in to defense.

    best of lk..

There might be something which you are looking for in this. If you find that something, please reply to this thread, so that i could elaborate about that.

    PCB in Science and technology:

    --> Printed circuit board, a board used in electronics
    --> PCB (software), software to design printed circuit boards
    --> PCBoard, bulletin board software for MS-DOS
    --> Polychlorinated biphenyls, organic compounds
    --> Plenum chamber burning, proposed jet engine technology for the thrust vectoring Rolls-Royce Pegasus engine
    --> Power circuit breaker, an automatically operated electrical switch
    --> Process control block, a data structure in software
    --> PCB Piezotronics, a manufacturer of piezoelectric sensors

    PCB is also the abbreviation for:
    --> Pakistan Cricket Board, regulatory board for cricket in Pakistan.

    Re: What is PCB?

    hello,
    pcb its a printed ccircuit board on which circuit design will be done its use to place the components according to the circuit printed on it components like ics , diodes ,capacitors , resistors conductors are arranged and they will be scoled using lead and scolder paste and they are two ways of scoldering tht is throught scolder rode with hand and other way is they do it in machine if u go to some company then u can see big big machins how they scolde the pcb components .

    Re: What is PCB?

    Dear friend.
    The PCB stands for the physics, chemistry and Biology subjects.

    This group of exams is better known as the medical group or the medical stream of education. As you know that the biology is the science of study of the physiology, anatomy and the morphology of the living beings that is why it is called as the medical stream.
    This stream is generally taken up by the candidates who want to be a doctor or a scientist or a physiotherapist.
    after taking up the combination of these subjects you have to study these subjects in details in 11th and 12th and after passing the 12th you have to choose from various medical courses of the country.
    some of these course are as follows:
    1. MBBS: This course is on the top as it is the topmost category of the doctors that treat the people with the allopathic medicines.
    To get the admission in the course you have to clear various entrances of the universities or the all India ones like the AIPMT, DPMT, UPCPMT, AMU, AIIMSetc...
    2.BDS: It is the second most popular course after the 12th medical taking you in the teeth and the dentistry aread. The entrances are common with that of the MBBS for this course.
    3.bsc. biotech/biomedical sciences/biosciences: This is the third most poular course after the dentistry and takes you towards the biotechnology field as a scientist in the hospitals and the top pharma companies.
    4.Bsc. botany/zoology: These courses are the scopeful courses but mostly in abroad making you a
    *ranger
    *wildlife reserver
    *environmentalist
    *scientist
    *professor
    *botanist
    *zoologist

    and there are many other courses too but hey will be available to you later after completing your 12th.
    so in all the PCB is the stream that is highly diverse and mainly consist of the scientist posts and professor type placements in various universities and the top pharma companies.

    Good luck

    Re: What is PCB?

    Dear friend, PCB is a Printed Circuit Board which is also known as a printed wiring board.

    Uses of PCB..

    * in electronics, to build electronic devices.
    * it serves two purposes in the construction of an electronic device.
    * it is the board to mount the components.
    * electrical connection between different components can be done through PCB.

    Composition of PCB

    A PCB is made up of a thin non-conducting sheet of material. The most common material used is a glass fiber epoxy laminate material. On each side of PCB a thin layer of copper is deposited chemically.

    thank you !
