ELECTRIC CIRCUIT -TYPES OF ELECTRIC CIRCUIT

What is an Electric Circuit

An Electric Circuit is the conductive path for flow of current or electricity is called electric circuit or electrical circuit. A conductive wire is used to establish relation among source of voltage and load. An ON / OFF switch and a fuse is also used in between the source and load.

Types of Electric Circuit

There are following 5 main types of electric circuit:

1. Close Circuit
When load works on its own in a circuit then it is called Close Circuit or Closed Circuit. Under this situation, the value of current flow depends on load.

HOW TO DESIGN A PCB LAYOUT

Breadboards are great for prototyping circuits, but they aren’t so good for actually using the thing you’re building. At some point, you’ll probably want to make a project more permanent. The best way to do that is to put it on a PCB.

In this tutorial, I’ll walk you through the process of designing a PCB layout and getting it printed by a custom PCB manufacturer. The performance of your circuit will depend greatly on how it’s laid out on the PCB, so I’ll give you lots of tips on how to optimize your design.

PCB MATERIALS | MATERIALS FOR BASE OF PRINTED CIRCUIT BOARD

A Printed Circuit Board (PCB) is a Board made of different heat resistant insulating materials. Conductive copper tracks are printed or etched onto this con-conductive base substrate. Electronic components are then soldered onto this board making it a Printed Circuit Board Assembly (PCBA).

PCB Materials can be classified according to their properties. The base material of a PCB (CCL – Copper Clad Laminate) is basically composite material made of dielectric layer (Resin, Glass Fiber) and conductor or high purity (copper foil). Let’s now understand different materials for base of Printed Circuit Board according to their properties.

A GUIDE TO PCB MATERIAL SELECTION

So you want to build your own PCB (Printed Circuit Board)? A material selection guide is as good a place as any to start. Your typical PCB consists of one or more layers of copper laminated between sheet layers of a non-conductive substrate. The PCB serves as the physical foundation upon which your electrical components, conductive traces, pads, and other features will reside. In this article we’ll dive into the materials and design considerations that go into each layer of a PCB: silkscreen, soldermask, copper, and substrate.

Silkscreen
There’s nothing more iconic than the white silkscreen contrasted against the backdrop of the classic green solder mask of a PCB. Silkscreen gets its name from the stenciling technique used to print markings, letters, symbols, numbers and other information onto a board. This layer’s primary purpose is to provide information for PCB assembly and identification.

TYPES OF SWITCHES IN ELECTRONIC CIRCUITS

Switches are an important part of most electronic circuits. In the simplest case, most circuits contain an on/off switch. In addition to the on/off switch, many circuits contain switches that control how the circuit works or activate different features of the circuit.

Switches are mechanical devices with two or more leads (or terminals) that are internally connected to metal contacts which can be opened or closed by the person operating the switch.

When the switch is in the On position, the contacts are brought together to complete the circuit so that current can flow. When the contacts are together, the switch is closed. When the contacts are apart, the switch is open and current cannot flow.

Metamaterials Show Promise for RF Circuits

Artificially created composite materials, also known as metamaterials, promise behavior beyond what is normally found in nature, such as dielectric materials with negative permeability and permittivity. In search of potential circuit applications for metamaterials, researchers from Australia’s Queensland University of Technology and Malaysia’s Universiti Kebangsaan Malaysia investigated the use of microstrip transmission lines and dual-star, split-ring resonators (DSSRRs) fabricated on metamaterials to achieve circuit sizes much smaller than normally dictated by quarter- and half-wavelength structures.

They explored left-handed (LH) and right-handed (RH) metamaterial media to better understand some potential capabilities of metamaterials for RF and microwave circuits.

Of Modeling and Materials

The role that material choice plays in the development of electronic circuits and systems is significant—hence the popularity of simulation software.

Materials play a large part in the future of electronic circuits and systems. The impact of gallium nitride (GaN) on commercial and defense radar systems, for example, has been profound over the last few years, providing transmit power at microwave/millimeter-wave frequencies while reducing the size and bias requirements of the older vacuum-tube devices they are replacing.

Materials Lay Foundations for Next-Generation Circuits

Circuit designers walking the 2017 IMS exhibit floor found a growing number of laminates tailored for higher-frequency circuits, as the industry in general looks to a growing demand for millimeter-wave circuits in automotive, commercial wireless communications, and military applications. For example, at IMS exhibition booth No. 1548, Rogers Corp. showed its RO4830 circuit laminates as cost-effective alternatives to PTFE for 77-GHz automotive radar circuits. These thermoset materials feature low dielectric constant of 3.2 at 77 GHz with extremely low insertion loss for microstrip transmission lines at that frequency. These circuit materials are compatible with lead-free-solder processes and can be fabricated with the same methods used for FR-4 (epoxy-glass) materials. Rogers will also show its RO4730G3 antenna-grade materials for designers of PCB antennas in need of low passive-intermodulation (PIM) levels.

What Are Printed Circuit Boards Used for?

In the early days of electronics, when vacuum tubes were king, all of the various components that made up an electronic device were connected together by soldering them either to each other or to terminal strips and tube sockets. Today, printed circuit boards have made connecting components simpler and cheaper.

What Are PCBs?
Printed circuit boards (PCBs) are thin boards made from an insulating material, with a metal coated surface, sometimes on both the top and bottom. Etches are made in the metal with acid to create pathways for electricity to travel among various components which are surface mounted on the board with solder.

PCB Advantages
The invention of printed circuit boards is one of the factors that has enabled electronic circuits to be smaller, more compact, and contained on a convenient, rugged board. Holes drilled into circuit boards allow components such as resistors and capacitors to be inserted and soldered through automation.

PCB Manufacturing Process: how are PCBs made

The PCB manufacturing process is very important for anyone involved in the electronics industry. Printed circuit boards, PCBs, are very widely used as the basis for electronic circuits. Printed circuit boards are used to provide the mechanical basis on which the circuit can be built. Accordingly virtually all circuits use printed circuit boards and they are designed and used in quantities of millions.

Although PCBs form the basis of virtually all electronic circuits today, they tend to be taken for granted. Nevertheless technology in this area of electronics is moving forward. Track sizes are decreasing, the numbers of layers in the boards is increasing to accommodate for the increased connectivity required, and the design rules are being improved to ensure that smaller SMT devices can be handled and the soldering processes used in production can be accommodated.
