What is Electronic PCB?

Printed Circuit Board or PCB is an electronic circuit which used in the devices for the purpose of providing mechanical support and a solid pathway to all its electronic components. The circuit is made with the combination of different sheets of the non-conductive materials like plastic and fiberglass etc. which can hold copper circuitry with ease.

What Does it Do?

PCB mechanically supports and connects the electronic and electrical components with the help of conductive tracks and pads and other types of features etching from one or more sheet layers of copper-laminated between the sheet layers of non-conductive substrate. Components of the electronic PCB are soldered generally onto the PCB to fasten it mechanically and to connect it electrically.

Where are these circuit boards used? Where to get them repaired?

PCB or Printed Circuit Boards are used in all types of simple electronic products. These are used in certain types of electrical products like the passive switch-boxes. If you think that the board is malfunctioning it is good to contact the company from where you have bought the switch-box if the product is in warranty. If it is not under warranty, you should contact only a certified and authorized Electronic PCB repair service.

What are the alternatives to PCB?

There are several alternatives to PCB including point-to-point construction and wire wrap. Both of these are very popular but they are used rarely now. PCBs need additional design efforts for laying out the circuit. There manufacturing and assembly can be automated. There arespecialzed CAD software which can do much of the layout work.Mass-producing circuits that have electronic PCB cost lesser and work faster than the other types of wiring techniques as components are mounted and wired in just one operation. Sometimes PCBs are made in small quanties, these have reduced benefits.

What are the various types?

PCBs can be single-sided with just one-copper layer or double sided with two copper layers on either sides of the substrate layer or they may be with multi-layer with the outer and inner layer of copper alternating with different layers of substrate.
These PCBs have higher component density. It is important to note that the multilayer PCBs make repair analysis and the field modification of the circuits become much more difficult and absolutely impractical.

There is yet another important part of the electronic devices other than PCBs which is little-known to many. It is a servo drive. It is a special type of electronic amplifier which is used for powering electric servomechanisms. This drive screens the feedback signal from the servomechanisms and adjusts the deviations from the anticipated behavior. If you think that this amplifier of your device is malfunctioning get it repaired from a certified servo drive repair service.
