General Indicators of Failed Components and Reasons Behind the Failure

There are numerous reasons that may result in component failure.  When you Buy electronic component, the component failure is a common situation. The chance of failure drops are increased as they are used. A failure of a component within a system may be due to factors like misuse, wearing-out, or as a consequence of the failure of another system component. Failure is detected when the system does not function the indented work. Component failure may be difficult to identify. Following are the indications that can help you identify the failed components.

Sell Overstock Inventory

Visible- Visual inspection is the most obvious indicator that a specific component has failed. Failed components are depicted by burnt or melted areas or are bulges and expanded. Capacitors are often bulged out. IC packages often have a small hole burned in them.

Smell– A thermal overload occurs due to the failure of the component that causes blue smoke to be released by the damaged component. The smoke also has a very distinct smell and varies by type of component. The smell remains around the component for days and which can help in identifying damaged component during troubleshooting.

Sound- Components makes the brittle sound that indicated that it may have failed. This happens more often with rapid thermal failures, over voltages and over current. When a component fails this suddenly, a smell often accompanies the failure. The components of the system are found loose in the circuit that results in sound, so identifying the component that failed may come down to finding which component is no longer on the PCB.

Testing– Individual testing of components is required to identify the components that have failed. It is quite difficult on a PCB as other components will affect the measurement since all measurements involve supply of current or voltage, the circuit will respond to it and readings can vary. If a system uses several sub systems, often replacing them is a great way to find the issue in the system.

Sometimes the failures are slow and it becomes difficult to identify the component and replace it before it fails completely and the equipment is down. Other failures may be rapid, violent or unexpected. These failures are tested during the certification testing. For repairing of the damaged circuits lots of testing, probing and prepping and then the repair work.

Some Of The Most Common Failure Modes of Electronics

Electronic component failure occurs  most commonly at the beginning and near the end of the lifetime of the parts. The failure of components is typically packaging related. Sometimes the failure is slow which gives time to identify the component and replace it before it fails completely destroying the equipment.

While the failures may be rapid or violent and unexpected, these are tested for during product certification. Some of the most common reasons for components to fail include:

•    Over-current and over-voltage

•    Over temperature

•    Radiation

•    Contamination

•    Packaging

•    Connected incorrectly

•    Manufacturing defect

While you buy electronic component you need to understand that everything fails at some point and electronics are no exception.

The following major failure modes can help designers create more strong designs and even plan for expected failures.

Component Package Failures

The components are properly packed to provide two main function, to protect the component from environment and to provide a way for the component to be connected to the circuit. It may happen that the packing layer may break, thus the outside factors such as humidity and oxygen can affect the ageing of the component and cause it to fail much faster. The component can also be subject to mechanical failure of the package caused by thermal stress, chemical cleaners, and ultraviolet light.

Solder Joint and Contact Failures

The main means of contact between a component and circuit is the solder joint. If you use a wrong type of solder with the component or PCB it can lead to electro migration of the elements in the solder that form fragile layers called inter-metallic layers. These layers lead to broken solder joints.

Another reason for solder joint failure is thermal cycles, especially if the thermal expansion rates of the materials are different. As all of these materials heat up and cool down, massive mechanical stress can damage the component, or the PCB trace may be divided into layers. Tin whiskers on lead free solders can also be a problem.

PCB Failures

Printed circuit boards are susceptible to environmental influences. The soldering and operational environment of a PCB often leads to a variety of PCB failures. Residues of solder flux may aid corrosion, and other materials on PCBs can cause electrical leaks. Other causes of failure include stemming from the manufacturing process. During manufacturing the layers in a PCB board may be uneven leading to short circuits, open circuits, and crossed signal lines. The chemicals used in PCB board drawing may not be fully removed and traces may be formed. The solder flux used to attach all of the components to a PCB may remain on the surface of a PCB which will corrode any metal that comes in contact with it. Thermal cycling is another cause of PCB failures which can lead to de-lamination of the PCB.

All these causes can be prevented by adjusting the design of the circuit accordingly. These failures like mechanical failure, packaging failures etc can be avoided by taking proper care.

The Basic Electronic Components that Are Commonly Used

Electronic components have two or more electrical terminals unlike antennas which may only have one terminal. When building electronic circuits, there are some basic electronic components commonly used. It is quite difficult to identify the components through its value and the more confusing task is to identify pin outs. To get an idea about the components you can refer to the function of some of the basic components.

Capacitor

Capacitor is capable of storing charge. Capacitor is used for frequency selection and for  mixing ac signals from one circuit to another etc. The assembly of capacitor consists of two metallic plates separated by dielectric. Capacitor is capable of voltage handling beyond which the capacitor dielectric breaks down.

The capacitance is defined as : C = Єo Єr A / d

A is the area of plates

d is plates separation

Єo is permittivity of free space

Єr is relative permittivity.

Resistor

A resistor is a common electronic component that will resist the current flow in an electric circuit. Resistor set up correct voltages in a circuit to make it work properly.

Diode

A diode helps in conduction of electricity in one direction. They can be used in series switching or shunt switching in place of relays.  It is commonly used if you want to convert from alternating current (AC) to direct current. Light Emitting Diode (LED) and Zener diode are other types of diodes used.

Integrated Circuit (IC)

An integrated circuit is a circuit made up of various tiny components, tiny resistors, capacitors, and transistors are fabricated and placed in a small package. An IC can function as an amplifier, oscillator, timer or microprocessor.

Basic components may appear simple but they are not that simple. You will need to work with a number of basic electronic components when building circuits. There are many reputed retail companies which Sell Overstock Inventory electronic components and have a good stock of electronic component that you may need any time.

Electric Circuits – Working and its Types

What happens when you switch on a T.V, light or a computer? What is the process going in through these systems? All these system are made of electric circuits, which in turn is made from Electronic Components. The electric circuit function allows current, or flow of electrons, through the wires. The wires in electric circuit carry current through the wires throughout the system just like the blood in our circulatory system.

Below are some of the types of electric circuits used in different systems:

A closed circuit has a complete path for current to flow. This means that it has a complete electrical connection around which current flows or circulates.

An open circuit doesn't have a complete path for current to flow which makes it non functional. In this electrical circuit the continuity is broken so that current does not flow.

A short circuit is responsible for bypassing the part of the circuit, as it has a low-resistance path, usually made unintentionally. This may happen when two exposed wires in a circuit touch each other. The part of the circuit bypassed by the short circuit will not function and a large amount of current will flow. This sometimes generates a lot of heat in the wire and may cause fire.

In a series circuit, through all the components same current flows. Across the whole circuit the total voltage is the sum of the voltage across each component and the total resistance is the sum of the resistances of each component.

In a parallel circuit the current flows through more than one path. Across each component of the parallel circuit the voltage is the same. The sum of the currents through each path is equal to the total current that flows from the source.

Electric circuits are generally complex combinations of series and parallel circuits. It has several applications and the electric lighting is the first application of this for practical use.
