What is PCB Design and What are the Different Types of PCB Design? Presentation Transcript

Slide 1 - What is PCB design and what are the different types of PCB design? Introduction An electrical circuitry consisting of embedded metal lines known as traces and bigger metal portions known as planes is located on a solid structure known as a printed circuit board. Printed electronics is a rapidly developing PCB technology that is distinct from the ones mentioned above; it typically consists of very simple, very inexpensive circuits that reduce the cost of electronic packaging to the point where electronic solutions can be developed to address issues that have never been considered before. What is PCB design? Printed circuit boards are the fundamental building blocks of the bulk of modern electronic devices (PCBs). Printed circuit boards are the foundation upon which all other electronic components are built, whether
Slide 2 - they are simple single-layered boards like those found in garage door openers, six-layer boards like those found in smartwatches, or 60-layer, extremely high density, high-speed circuit boards like those found in supercomputers and servers. The PCB is used to connect and communicate with radio equipment, resistors, diodes, capacitors, and semiconductors. The board can be made up of a single layer of circuitry, circuitry on the top and bottom, or numerous layers of electronics stacked together. What Are Printed Circuit Board (PCB) Materials? In most situations, printed circuit boards (PCBs) are flat laminated composites comprised of non-conductive substrate materials with layers of copper circuitry buried internally or on the outside surfaces. They might be as simple as one or two copper layers, or as complex as fifty layers or more in high density applications. While the copper wires connect the components electronically, the flat composite surface is ideal for supporting the soldered and linked components to the PCB. The six basic components of a typical printed circuit board are as follows: Prepreg Laminate Copper foil Soldermask
Slide 3 - Nomenclature Final Finish Prepreg is a thin glass fabric that has been resin-coated and dried in prepreg treaters, which are specialised machines. The mechanical support system that holds the resin in place is made of glass. Prepreg sheets, often known as fibreglass, are used to make a variety of products including as boats, golf clubs, aeroplanes, and wind turbine blades. However, PCB production is also dependent on it. The laminate, the second component of a PCB, is made from prepreg sheets, which are also used to assemble the PCB Why Are Printed Circuit Boards Used? The bare board that you provide us with layout data for and use to attach your components once we provide it to you is known in the industry as a PCB, or printed circuit board. Printed circuit boards, or PCBs, mechanically support and electrically connect electronic components by using conductive channels, tracks, or signal lines etched from copper sheets laminated onto a non-conductive substrate. Printed wire (circuit) boards are used in nearly all commercially produced electronic devices today, allowing for completely automated assembly operations that were not possible or plausible with older tag type circuit production techniques. Types of Printed Circuit Boards Printed circuit boards :
Slide 4 - Despite the fact that (PCBs) are the brains of all electronic goods, not all PCBs are created equal. Printed circuit boards are available in a wide range of shapes, sizes, materials, and manufacturing requirements to suit a wide range of applications. Double Layer PCB A conductive layer is placed on top of a non-conductive substrate in double layer PCBs, and a second conductive layer is placed on the back (top and bottom layers). It is possible that the two conductive sides could It is called vias. Vias are used to link components by passing them through plated holes in the substrate that connect to pads on both sides of the circuit board. Multi-Layer PCB This term refers to three or more conducting layers on a circuit board. The conductive layers are at the top and bottom, and at least one conducting layer is sandwiched between two non-conductive substrates. High Density Interconnect (HDI) PCBs HDI PCBs use precision-based manufacturing technology to pack as much functionality as feasible into a small space. To accomplish this, numerous conductive layers, laser-drilled microvias, exact lines and tolerances, and cutting-edge laminate materials are needed. High Frequency PCB
Slide 5 - The key area of diversity in the fabrication of high frequency printed circuit boards is the design itself. These PCBs are designed to sustain transmissions at speeds greater than 1 GHz. The Benefits of Printed Circuit Boards PCBs are affordable, allowing for low-cost mass fabrication. It is changeable. easily accessible excellent shelf life Electronic noise is minimal. Wire conservation and compact size Conclusion Printed circuits allow specialists working in a variety of industries to optimise the performance and output of their electronic systems. By carefully selecting materials and PCB fabricators, you may make your electronic device's packaging best suited for its intended function.
