The acronym of the printed circuit board is PCB, it is a self contained board with interconnected electrical and electronic components found in various devices ranges from beepers to pagers, radios, radar and computer systems. The circuits are produced by a slight layer of conducting material deposited on the outside of an insulating board called as the substrate. Separate components are located on the surface of the substrate & soldered to the connected circuits. The construction of the PCB can be done in three ways, namely single sided, double sided and multi layered.The components on a PCB are connected electrically to the circuits by two different methods such as hole technology and surface mount. In hole technology, every component consists of thin leads, which are pressed through tiny holes in the substrate & soldered to connection boards in the circuits on the reverse side.In surface mount technology, J-shaped or L-shaped terminals on every component get in touch with the PCB directly. A solder paste includes a glue, solder and flux are applied at the contact point to grip the components in position until the solder is liquefied.
Types of PCBs
Different Types of Printed Circuit Boards
PCBs have copper tracks to connect the holes where the various components are located They are specially designed for each and every circuit and build construction very easy. Though, making the PCB necessitates special tools. The different types of printed circuit boards mainly include the following
Single Sided PCBs
Double Sided PCBs
Multilayer PCBs
Rigid PCBs
Flex PCBs
Rigid-Flex PCBs
Single Sided PCBs
This single sided printed circuit board includes just one layer of base material or substrate. One end of the substrate is coated with a thin layer of metal, usually copper because it is a good electrical conductor. Generally, a protecting solder mask be seated on the peak of the copper layer, and a last silkscreen coat may be applied to the top to mark elements of the board.
Single Sided PCBs
This PCB consists of various circuits and electronic components on the only single side. This kind of module works most excellent for easy electronics, and beginners often design and build this type of board first. These boards tend to cost less to mass-produce than other types of boards. But although this low cost, they’re used rarely because of their intrinsic design limitations.
Double Sided PCBs
This type of PCBs is much more familiar than single-sided boards. Both sides of the board’s substrate include metal conductive layers, and elements attach to both sides as well. Holes in the PCB let circuits on a single side to attach to circuits on the other side.
Double Sided PCBs
These kind of circuit boards used to connect the circuits on every side using one of two techniques: through-hole & surface mount technology. Through-hole technology engages feeding small wires, called as leads through the holes & soldering every end to the suitable component .
Surface mount technology is different from through-hole technology, it does not utilize wires. In its place, many little leads get soldered straight onto the board. Surface mount technology permits many circuits to be complete in a lesser space on a board, meaning the board can execute more functions, typically at a lesser weight and at faster speeds than through-hole boards let.
Multilayer PCBs
These PCBs further enlarges the density and complexity of PCB designs by adding extra layers beyond the top & bottom layers seen in a configuration of double sided. With the accessibility of over many layers in multilayer printed circuit board configurations, multilayer PCBs let designers to make very thick and highly compound designs.
Multilayer PCBs
The extra layers used in this design are power planes, which both provide the supply to the circuit with power and also decrease the levels of electromagnetic interference which are emitted by designs. Lower EMI levels are attained by placing signal levels in the middle of power planes.
Rigid PCBs
In addition to having different numbers of layers & sides, Printed circuit boards can also come in changing inflexibilities. Most customers usually think of inflexible PCBs when they image a circuit board. Rigid printed circuit boards use a solid, rigid substrate material like fiberglass that remains the board from twisting. A motherboard within the tower of a computer is the best example of an inflexible PCB.
Rigid PCBs
Flex PCBs
Generally, the substrate in a flexible board is a flexible plastic. This fundamental material permits the board to fit into forms that inflexible boards cannot & to turn or shift during use without harmful the circuits on the printed circuit board. Though flex boards tend to charge more to intend and create than rigid PCBs, they come with a number of advantages. For instance, they can restore heavy or bulky wiring in superior gear like satellites, where weight & space matter. Flex boards can also come in three formats, namely single sided, double-sided or multilayer formats.
Flex PCBs
Rigid-Flex PCBs
Rigid flex boards merge technology from both flexible and rigid circuit boards. An easy rigid-flex boards comprises of a rigid circuit board that joints to a flex circuit board. These boards can be more compound if design requests demand.
Rigid-Flex PCBs
Thus, this is all about different types of printed circuit boards, which includes Sided PCBs, Double Sided PCBs, Multilayer PCBs, Rigid PCBs, Flex PCBs, Rigid-Flex PCBs, etc. We hope that you have got a better understanding of this concept Single.
