The History of Circuit Boards

Printed circuit boards, which are also known as the printed wiring cards or printed wiring boards, physically connect two or more electronic components together. These are parts of an electronic device which create a circuit in order for the electronic device to work. Printed circuit boards are usually found in computers, like the mother board for an example. They can also be found in other electronic devices such as a mobile phone, a television, a calculator, an electronic wristwatch, a tablet or just simply any device which runs using electricity.

When Did It Start?

The printed circuit boards started as early as the year 1900s. In 1925, Charles Duncan, created an electronic pattern directly printed onto an insulated board. This was improved after the Second World War, by the year 1943, when Paul Eisler was able to build a fully functional printed circuit board.

PCB-FabricationBefore printed circuit boards were developed, the point-to-point construction was used first. People used wires to connect each electronic device together. However, devices which were made to work using this method were usually big and bulky in size and users are usually experiencing device breakdown. Once the device breakdowns, repair is needed and this repair usually requires replacement of the wires or the connecting sockets of the circuit board. During these times, the wires are usually weak and upon insulating electricity, these wires wear down, which causes the device to short circuit.

By the year 1920s, most radios and gramophones took advantage of circuit boards. To prevent the devices from experiencing short circuit, woods were used to fit the device to rivet the circuit board.

The printed circuit boards were highly regarded and highly improved during the years 1950s to 1960s. Some patents were made in order to give enhancement in the design and efficiency of the circuit boards. At first, the circuits were printed on one side of the circuit board. Eventually, multilayered circuit boards were invented, wherein a lot of circuits can be directly printed onto one circuit board.

How Does It Work?

Most circuit boards are made of conductive material, usually copper. A thin foil of copper is etched onto the board. All lines and connections of the circuit board are designed to reach and connect with the electronic component properly to prevent any possible issues. These patterns are done on both sides of the board. However, to create cheaper ones, the pattern is printed on one side only, particularly at the bottom.

A printed circuit board have a hole where you can place any electronic component wiring by inserting it through the hole and then soldering it to keep it in place, either by hand or through the use of a soldering machine. The hole, where the electronic component is placed, has a copper ring (also known as the annular ring). For some printed circuit board, you need to connect two or more boards in order to make it work. There will also be some times when the circuit board needs to be cut in places (either by v-score or mouse bite cut, both cuts are partial cuts on the board) so they can easily fit in place.

In order to protect the copper paths which makes the circuit, the circuit board will be placed with a soldermask. The soldermask gives the circuit board the common green color. It protects the circuit and prevents any solder jumper to break apart the circuit. Some components in the circuit board are not put in by holes. Some components have slots for parts which are not round in shape.

Lastly, a silk screen is used to provide a label for each electronic component. This is to ensure that anyone who will be looking at the circuit board will be able to recognize the parts easily.

PCBs have become an important part of a wide range of machineries, computing devices, automobiles, appliances, and other electronic gadgets. Visit www.pcbnet.com for more detail information.
