How To Assure The Quality Of Electronic Components?

Every electrical application requires various parts to function properly. And for long functionality, it is essential that appropriate and high quality Electronic Components are used in application. But, how can you ensure the quality of these products.

But why the quality assurance is essential?

The biggest reason to ensure quality is the high number of counterfeit products in market. When it comes to components, there are many fraudulent and counterfeit parts that increase the chances that you might purchase the wrong one. It can lead to problems with your electrical applications as counterfeit parts do not work as good as the real one.

So, it is vital that you buy the original and quality certified parts for your equipment. There are four major quality assurance methods that these manufacturers of these products use and you can trust. It includes ESD Certification, ERAI Certification and ISO Certification.

It is advised that you purchase these components from a respected and reliable buyer so that you rest assured about the quality of products. Reliable and renowned suppliers ensure that they provide good parts only as it affects their reputation and customer base in market. They also inspect each product before supplying or selling it to clients.

Furthermore, you should make sure that the supplier you are relying on, purchases products from domestic OEMs and defence contractors. With this, you can ensure that each component that you purchase can be traced easily. In addition, make sure that the supplier follows certain quality assurance procedures and resources.

It includes microscope analysis, testing & screening, solder ability testing and acetone tests. Packaging matters too when it comes to components. You can ask the supplier if they provide custom packaging that match up to military spec standards. With this, rest assured that you will get the right product with proper quality and in appropriate packaging.

How to Choose A Distributor To Sell Your Excess Inventory

The most essential thing you must do when you are going to sell your excess electronics inventory is to choose an Independent Distributor. The distributor you choose always determine the return on your investment.

Make sure to visit the facility and take a good look around. When interviewing an Independent Distributor check that they have proper manpower and technical support. Certain things need to be verified before you finalize the deal:

• ISO Certification

ISO certification tells you that Quality Management System of the company is in place and that the system has been reviewed by an outside auditor and the company's own management team. Unless the supplier is ISO certified, many buyers will not add a supplier to their Approved Supplier List.

• Determining The Value Of A Component

Determining market price for components can be a difficult thing. Some companies check pricing of franchising a web site; while this might be a good start, open market pricing is based upon demand and supply. The type of software tools used, detailed information concerning supply, and competitive pricing help in calculating the price of the inventory.

• How Many Unique Customers Do You Sell To Each Year?

The volatility and uncertainty of the open market makes supplier relationships really important in today's market. People do business with the ones that they trust. You'll want to evaluate whether the company hires educated, intelligent, educated, and innovative employees who are able to develop and use the tools they will need to sell your inventory. There should be atleast one engineer on staff who can resolve technical questions that could otherwise lead to lost sales.

The software the the Independent Distributor business uses is extremely important. When you visit facility of the company, ask for a demonstration of the software they will use and pay attention to how they monitor demand and supply and how they determine market price.

Faulty electronic parts can cause the whole product to crash and even stop working very early on in its product life-cycle.

Reliability is one of the important attribute which determines quality of electronic components for safety of components. Both manufactures and customers of electronic components should define the reliability in a common way. Reliability prediction is the process that determines the performance ability to perform the required function without failure during its life. Reliability prediction is done during concept, development and maintenance phase. In order to understand the concept of reliability failure needs to be defined.

There are many companies who sell surplus electronic components. A good indicator of a trusted supplier is how large their volume of stock is and how quickly they can send it to you. You can also keep an eye out for certifications in, ISO, AS, ASNI/ ESD.

Soldering Safety and Advice for Different Electronic Components

Soldering involves a process of joining two or more metals by melting and putting filler metal into the joint. Flux is used to facilitate the soldering process. For this purpose, filler materials are available in different alloys for various applications. In electronics assembly, the alloy of 63% tin and 37% lead is the most commonly used.

Some of the Basic Electronic Components and their Functions

When building electronic circuits, we need to work with some of the basic electronic components including resistors, capacitors, transistors, integrated circuits etc. Some of these components are called active components because they are involved in transformation of the energy while other components, that only dissipate energy, are known as passive elements.

Passive components are also called electrical elements. Some of the examples of passive components are:

Resistors:

A resistor is one of the basic components used in electronic circuits that resist the flow of current.

Capacitors:

Capacitor is the second most commonly used component in electronic circuits. It can temporarily store an electric charge. Capacitors come in different varieties, the two common types being ceramic disk and electrolytic. The amount of capacitance is usually measured in micro farads μF.

Diode:

Through diode, the current flows in only one direction. A diode has two terminals, called the anode and the cathode. Current will flow through the diode, when positive voltage is applied to the anode and negative voltage to the cathode. Current will now flow when these voltages are reversed.

Active components are those that have gain or directionality. Example: transistors, integrated circuits or ICs, logic gates. Active components can be further classified as semiconductor devices such as semiconductor diode, zener diode, Varactor diode etc.

Transistor:

A transistor has three terminals called base, collector and emitter. In this a voltage applied to one of the terminals can control current that flows across the other two terminals. The transistor is one of the most important devices in electronics.

Integrated circuit:

An integrated circuit consists of entire components including electronic circuit, complete with transistors, diodes, and other elements. Integrated circuits are the building blocks of modern electronic devices such as computers and cell phones.

All these components are essential for the building of any electronic components. If you want to buy any of these Electronic Components, you can contact a dealer who has a surplus distribution of electronic components.
