Circuit Board

Dating back to its successful stint during the World War II, the Circuit board has traveled a long way as it is used even in space crafts and satellites. Invented by Paul Eisler, its manufacturing stayed under military control till the 1930s. Its popularity grew by the end of the war.

Traditionally, its components were connected on the board via wiring but modern boards have inlaid copper threads for effective connection. Other facts about circuit boards are that:

* they are critical components for electrical appliances.
* they act as a base plate where circuit components can be mounted for electrical connections.
* they help to organize electronic circuitry.
* they help to conserve energy.

Types of Circuit Boards

Electronic circuit boards are divided into two broad categories, namely those used for experimental purposes and those for commercial or industrial usage. However, the following three types of circuit boards are worth considering as they are easily available in the market:

Breadboard: This is useful in many ways such as:

* It serves the purpose of testing by making temporary circuits.
* A breadboard does not require soldering to fix the components on this board.
* It is a cost-effective alternative to professional boards.
* It can be re-used multiple times to make test circuits.

Stripboard: These boards, with their large number of holes to facilitate ease of connection, are used for the following purposes:

* to make permanent soldered circuits with high durability.
* as an ideal choice for circuits with 2 or 3 ICs.
* to act as a conductive base due to its copper plating on one side.
* Components are placed on the non-copper side and soldered to the copper tracks.

Printed circuit board (PCB): Also known as a printed wiring circuit board, the PCB has the following features and uses:

* It comprises a base plate of non-conducting material such as glass fibers.
* Copper is enameled over both the sides to allow the flow of charge.
* PCBs are specifically prepared for each circuit diagram.
* Each circuit diagram is chemically pasted on either side of the plate.
* The board is then treated with acid to remove copper deposition.
* The resultant of this process is a circuit board with inlaid circuit diagram and copper threads.
* Lastly, a protective metal layer is coated on both sides to avoid copper corrosion.

By manufacturing printed circuit boards since 1968, PNC Inc offers a variety of printed circuit boards with the latest technology in place.
